Rivet guns and rivet nut tools sit in that awkward middle ground of any garage or shop: cheap enough to ignore, specialized enough that a wrong choice wastes a Saturday. The right tool pulls panels together, builds blind threads in sheet metal, and repairs the kind of things adhesives cannot reach. This roundup focuses on manual and hand-powered options that suit home mechanics, fabricators, and weekend builders, with a close look at thread coverage, grip length, and what actually arrives in the box.

A Deeper Look At The Lineup
Most shops end up needing both imperial and metric threads sooner or later, and the 860-piece ASKWAY kit sidesteps that problem by including ten thread sizes in one labeled case. It pairs a manual rivet nut tool with 430 carbon steel nuts in SAE grades and 430 more in metric, covering everything from small 6-32 work up through 5/16-18 and M8. For anyone building or repairing mixed-fleet equipment, the breadth here eliminates the back-and-forth of separate kits.
The storage box stands out as a real practicality play. Each compartment is labeled, so you spend less time digging for the right M6 nut and more time working. In a busy garage, that kind of organization adds up across a weekend.
What Helps Most
- Ten thread sizes cover the common SAE and metric range in one purchase
- Carbon steel construction handles standard steel and aluminum panel work
- Labeled storage case speeds up the hunt for a specific size
- High piece count means you stay supplied through several projects before restocking
- Single tool body swaps between sizes without a separate wrench for each
Things To Consider
- Carbon steel nuts are best for indoor or coated applications, since outdoor exposure can corrode them over time
- The manual tool requires solid hand pressure for the larger M8 and 5/16-18 sizes
Key Specs
Who It Suits Best
Shop owners and serious hobbyists who split time between American and imported equipment will find the dual-coverage here saves real money over buying two kits.
Consider Something Else When
The AKKTOL Pop Rivet Gun Kit fits users who need to set blind rivets rather than threaded inserts, since that tool targets a different joining method entirely.
Unlike the threaded-insert kits that lead the rest of this list, the AKKTOL pop rivet gun focuses on blind rivets, which are the kind you set from one side when you cannot reach the back of the panel. Its 13-inch two-handled design is the headline feature, providing the leverage needed for thicker aluminum and steel without crushing the rivet. For gutter work, automotive panel repairs, and sheet metal fabrication, that extra handle length is the difference between a clean set and a sore hand.
Five interchangeable nosepieces come with the kit, covering 1/8-inch through 1/4-inch rivet diameters. The included 210 blind rivets are enough to knock out a small project without a separate supply run.
What Earns Its Place
- Two-handed 13-inch build provides real leverage for heavier gauge metal
- Five nosepieces handle 1/8-inch up to 1/4-inch rivet diameters
- Includes 210 blind rivets so you can start a project immediately
- Long handles reduce the squeeze force needed per pull
Points To Note
- Blind rivets leave a mandrel stem to break off and collect, so cleanup is part of the routine
- The 13-inch reach can feel unwieldy in tight engine bay corners
Made For
Automotive restorers, gutter installers, and sheet metal fabricators who need a leverage-first tool for blind fastening.
Look Elsewhere When
The ASKWAY Rivet Nut Tool Set SAE & Metric 860 PCS is the better pick when you need reusable threaded inserts rather than permanent blind rivets.
The 420-piece ASKWAY kit zeroes in on SAE threads, which is the right call for anyone working primarily on American-made vehicles and equipment. Five imperial sizes cover 6-32, 8-32, 10-24, 1/4-20, and 5/16-18, the five you’ll reach for 90% of the time. The manual tool body is straightforward steel construction, and the labeled case keeps the count straight.
You trade breadth for focus here. Rather than splitting inventory between metric and imperial, this kit lets you load up on the threads you actually use.
The Practical Payoff
- Concentrated stock of the five most common imperial sizes
- Carbon steel nuts handle the loads typical of automotive and trailer work
- Compact case takes up less bench space than dual-system kits
Honest Caveats
- No metric coverage, so imported equipment will need a separate kit
- Carbon steel finish means the case should stay dry to prevent rust on stored nuts
Best Suited To
U.S. vehicle owners and home mechanics focused on domestic repairs where metric threads rarely show up.
Swap It Out When
The ASKWAY Pressure Rivet Nut Tool Kit 750PCS Metric is the better match for European cars, Japanese machinery, or anything that calls for M-class threads.
When a shop needs imperial rivet nuts in volume, the 770-piece ASKWAY kit earns its place. Six sizes run from small 6-32 fasteners up through heavy 3/8-16 nuts, with the bulk of the count sitting in 1/4-20 and 10-24. That distribution lines up well with fabrication runs where you burn through a hundred of one size before touching the next.
Compared to the 420-piece ASKWAY kit, this version stretches further by including the larger 3/8-16 and bumping the 1/4-20 stock to 250 pieces.
Real Benefits
- Six imperial sizes including 3/8-16 for heavy structural use
- 250-count 1/4-20 stock covers most production runs without restocking
- Includes mounting spindles alongside the rivet nuts in the same case
Worth Noting
- Larger case footprint takes up more shelf space than smaller kits
- Carbon steel still means indoor storage is the safe play for long-term nut preservation
Feature Snapshot
Right Fit For
Fabrication shops and small production runs where high piece counts and the 3/8-16 size actually get used.
Reach For A Different Pick When
The ASKWAY Rivet Nut Stainless Steel SAE & Metric 560 PCS is the smarter call for marine or outdoor work where plain carbon steel would corrode.
The move to 304 stainless steel is the entire story here. Where carbon steel rivet nuts eventually bleed rust onto a painted surface, stainless shrugs off the same exposure. For trailer work, marine hardware, outdoor equipment, and anywhere moisture shows up, that material upgrade pays for itself the first time you pull a panel a year later and the threads still turn.
Eight sizes cover a useful spread of SAE and metric threads, so you are not locked into one standard. Compared to the 860-piece ASKWAY carbon steel kit, you trade raw count for corrosion resistance.
Where It Helps
- 304 stainless steel resists rust in damp and outdoor environments
- Eight sizes span common SAE and metric threads
- Same labeled storage case as the carbon steel kits for easy sorting
- Strong hold on stainless panels without galling concerns in normal use
Trade Offs
- Stainless costs more per piece than carbon steel, so the 560 count is leaner than similar-sized carbon kits
- The manual tool still needs firm pressure on the larger sizes, with no mechanical advantage
Who Will Love This
Boat owners, outdoor fabricators, and anyone whose work lives outside where plain carbon steel would fail in a season.
Where Another Pick Suits Better
The ASKWAY Rivet Nut Tool Set SAE & Metric 860 PCS is the better value when corrosion is not a concern and you want sheer count in both thread standards.
Metric-threaded projects deserve their own dedicated kit, and the 750-piece ASKWAY version covers seven sizes from M3 up to M12. The M12×1.75 and M10×1.5 sizes are the rare finds here, since most small kits stop at M8. For European vehicles, motorcycle frames, and imported machinery, that upper range is what separates a useful kit from a frustrating one.
The manual tool body is built for these heavier threads, with enough leverage to set the M10 and M12 sizes cleanly.
Useful Strengths
- Seven metric sizes span the practical range from M3 to M12
- Includes the harder-to-find M10 and M12 sizes for larger machinery
- 750-piece count supports multiple builds before resupply
- Labeled case keeps the small M3 and M4 sizes from migrating together
Potential Drawbacks
- No SAE threads, so mixed-fleet work requires a second kit
- Larger M10 and M12 nuts demand firm hand pressure during installation
Quick Facts
Perfect Match For
Mechanics working on imported vehicles, motorcycle builders, and anyone who needs M10 or M12 threads without improvising.
Skip It When
The ASKWAY Imperial Rivet Nut Tool Kit 430pcs SAE is the better tool when your work stays in U.S. standard sizes.
The 420-piece SAE kit is the workhorse option for general home garage work. Five imperial sizes cover the bread-and-butter threads: 6-32, 8-32, 10-24, 1/4-20, and 5/16-18. Carbon steel construction keeps the kit affordable, which matters when the nuts get used up and replenished over time. For mounting accessories to a trailer frame or repairing a stripped panel, this is the kind of kit that lives in a drawer and gets pulled without thinking.
What Works In Its Favor
- Five imperial sizes match the most common home garage needs
- Carbon steel nuts hold up well in dry indoor and underbody applications
- Compact 420-piece count balances storage and supply
Where It Is Less Suited
- Carbon steel will rust if stored in a damp garage for long stretches
- No metric coverage for imported equipment repairs
- Lower 5/16-18 count may run short on heavier jobs
Who Should Grab It
Home mechanics and hobbyists who mostly work on U.S. vehicles and want a no-fuss, no-extras kit on the bench.
Another Choice May Suit
The ASKWAY ASE Pressure Rivet Nut Tool Kit 770pcs Imperial fits better when you need more 1/4-20 stock and the larger 3/8-16 size.
First-time rivet nut users tend to want a kit that explains itself, and the 430-piece ASKWAY version delivers on that. Five imperial sizes run from 6-32 through 5/16-18, with even 100-piece distributions on the smaller sizes so the count feels balanced. The manual tool is simple steel construction without extra moving parts to learn.
For someone setting their first ten rivet nuts, that straightforward approach matters more than peak piece count.
Standout Benefits
- Balanced 100-piece counts on the three smaller sizes reduce early burnout of one thread
- Simple tool design shortens the learning curve for new users
- Labeled case helps you find the right size without guessing
Room For Improvement
- 5/16-18 only has 25 pieces, so the largest size runs out faster than the rest
- No metric threads to grow into mixed-fleet work
Built With In Mind
First-time buyers and weekend DIYers who want a forgiving, no-extras introduction to rivet nut installation.
A Better Fit Elsewhere
The AKKTOL 1/4 Inch Pop Rivet Gun Kit with 210pcs Blind Rivets suits users who need to join metal with blind rivets rather than install threaded inserts.
The 430-piece metric kit is the right size for smaller projects and tighter workbenches. Five sizes run from M3 up to M8, skipping the larger M10 and M12 sizes found in the 750-piece version. That focus on small threads makes it well suited to electronics enclosures, computer cases, 3D printer frames, and other assemblies where the M3 and M4 sizes do most of the work.
You trade the heavier metric range for a smaller case footprint, which matters in apartments and shared workspaces.
Everyday Perks
- Small metric range (M3 to M8) suits electronics and small assembly work
- Compact case fits on a small shelf or in a drawer
- 160 M3 pieces cover long runs of small enclosure work
Things To Consider
- No M10 or M12 sizes, so larger machinery repairs need a different kit
- Manual tool requires patience on the tighter M3 threads
- Only 20 M8 pieces means the larger end of the range runs out fast
Whose Shelf It Belongs On
Electronics hobbyists, PC builders, and small-format fabricators who need M3 and M4 in volume and nothing larger.
Not Your Match When
The ASKWAY Pressure Rivet Nut Tool Kit 750PCS Metric is the smarter buy when M10 and M12 threads are part of your workload.
What Matters Most Before Choosing Rivet Guns
Thread System and Size Spread
Rivet nuts (also called rivet nuts or threaded inserts) come in two main thread systems: SAE/imperial, used in American-made equipment, and metric, which dominates imported vehicles and machinery. A kit that covers only one system forces you to buy the other later, while a mixed kit spreads the count thinner per size. Match the thread system to your actual workload first, then look at whether the size spread reaches the largest fastener you expect to set.
Material and Corrosion Resistance
Carbon steel rivet nuts handle dry, indoor, and coated applications well and cost less per piece. Stainless steel, especially 304 grade, holds up to moisture, road salt, and marine environments but raises the price noticeably. For trailer hitches, boat hardware, and outdoor equipment, the upgrade pays off in fasteners that still unscrew years later. For indoor panels and shop projects, carbon steel is the practical pick.
Tool Ergonomics and Leverage
Manual rivet nut tools rely on hand pressure, so handle length and grip shape matter. A two-handed tool like a 13-inch pop rivet gun spreads load across both hands and reduces fatigue, while a single-hand rivet nut tool works for lighter thread sizes but demands more force as sizes climb. Look at the largest size in the kit and ask whether you can set it comfortably without bracing the tool against a bench.
Kit Count and Storage
Piece count affects how long before you restock, and storage layout affects how fast you can find the right size mid-project. Labeled cases with separate compartments prevent the M3 and M4 nuts from mingling, which sounds minor until you spend ten minutes sorting them on the floor. Higher piece counts in popular sizes like 1/4-20 and M6 indicate the kit is sized for real work, not just a sample of each thread.
Key Considerations Across These Picks
Wrong Turns To Avoid
One common slip is buying a metric kit for an American vehicle or vice versa, then realizing the threads never match. Another trap is overlooking the largest size in the kit, only to find the M10 or 5/16-18 nuts you actually need are absent. Always check the included size list against the largest fastener in your typical repair before committing to a kit.
What The Higher Tier Buys
Stepping up to a stainless steel kit or a larger-piece-count option costs more up front, but the upgrade usually shows up as longer service life and fewer mid-project restocks. For anyone working in damp or outdoor conditions, the stainless upgrade is the kind of purchase that pays back the first time a fastener still turns after a winter. For high-volume fabrication, the 770- and 860-piece kits reduce the time spent reordering, which is its own form of savings.
Frequently Asked Questions
What is a rivet nut and how is it different from a rivet?
A rivet nut is a threaded insert that you install into sheet metal to create a strong, reusable thread. A standard rivet is a solid fastener used to join two pieces of material permanently without threads. Rivet nuts let you bolt into thin metal where a regular nut cannot reach the back side.
Can I use the same tool for both metric and SAE rivet nuts?
Most manual rivet nut tools in this list accept both thread standards, but you swap the mandrel and nosepiece to match the size. The tool body itself is generally universal, so owning a mixed kit does not require two separate tool handles.
How do I know what size rivet nut to use?
Match the rivet nut thread to the bolt you plan to use, and match the rivet nut body diameter to the hole you drill in the panel. Most kits include a sizing reference in the case label or instruction sheet to cross-check the size against common bolt standards.
Are manual rivet nut tools strong enough for stainless steel panels?
Manual tools work for thin stainless steel panels in the smaller thread sizes, but heavier gauge stainless or larger M10 and M12 sizes can wear out a manual hand quickly. A pneumatic or cordless rivet nut tool reduces the strain for production work.
How should I store carbon steel rivet nuts to prevent rust?
Keep the case closed and store it in a dry indoor space, ideally with a small packet of desiccant to absorb moisture. For long-term storage, a light coat of light oil on the nuts adds a buffer against humidity.
