AIUITIO 16" Rivet Nut Tool Kit — 13 Mandrels (Metric & SAE), 200 Rivnuts, Quick-Change Head

The AIUITIO 16" rivet nut tool kit is a heavy-duty hand riveter set that installs threaded rivet nuts (rivnuts) quickly across metric and SAE sizes and stores neatly in a tough carrying case.

This compact kit bundles a 16-inch, carbon-steel hand rivet nut tool with a toolless quick-change head, 13 interchangeable mandrels to cover common metric and SAE threads, and 200 assorted rivet nuts for fast on-site repairs and installations. Built for workshops, garages, and DIY projects, the tool balances leverage with portability so you can set strong, reusable threaded inserts into thin sheet metal, plastics, and other materials without a power source.

How does the quick-change head save time during projects?

The toolless quick-change head lets you swap mandrels and nose pieces by hand, reducing downtime between different rivnut sizes. No wrenches or extra tools are required, so you can move from one threaded insert to another with minimal interruption.

• Hand-changeable mandrels for metric and SAE sizes
• Preinstalled M8 mandrel for immediate use
• Faster size transitions compared with screw-in systems

What materials and build features make this tool durable?

The 16" body uses thick, heat-treated carbon steel with black phosphating to resist corrosion and improve longevity. Its U cross-section arm design offers high rigidity to resist bending under heavy leverage, making it suitable for repeated use in demanding environments.

• Heat-treated carbon steel construction
• Black phosphating finish for corrosion resistance
• Robust U cross-section arm to prevent bending

Which rivnut sizes and accessories are included, and how many?

The kit supplies 13 interchangeable mandrels covering common metric threads (M3–M12) and SAE threads (8-32 through 1/2-13), plus 200 rivet nuts in useful quantities for most small-to-medium jobs. Note: the M8 mandrel comes preinstalled, so its small parts box appears empty.

• Mandrels: M3, M4, M5, M6, M8, M10, M12 and SAE 8-32, 10-24, 1/4-20, 5/16-18, 3/8-16, 1/2-13
• Rivnuts: 200 total — larger counts for common sizes, fewer for larger threads
• Rugged carrying case keeps all pieces organized and portable

What jobs is the AIUITIO rivet nut tool best suited for?

This hand riveter works well for installing threaded inserts in thin metal, plastic panels, brackets, and repair plates where welding or tapping isn’t practical. It’s a practical choice for automotive attachments, bicycle accessories, sheet metal fabrication, and general maintenance tasks.

• Automotive and motorcycle bracket mounting
• Bicycle and sporting equipment attachments
• Appliance or furniture repair where threads are needed

Who is this for: The AIUITIO 16" rivet nut tool kit is aimed at mechanics, fabricators, hobbyists, and home DIYers who need a reliable, manual method to create threaded anchor points in thin materials. If you want a portable, corrosion-resistant hand tool with a wide range of mandrels, preloaded rivnuts, and a sturdy case for organized storage and transport, this kit covers those needs without requiring air tools or electric riveters.
