GIANTISAN 16in Rivet Nut Tool Kit — 12 Mandrels, 316-Piece Assortment and Long-Arm Leverage for Easier Installation

This complete rivet nut installation set is built for professionals and DIYers who need a simpler way to create strong, threaded anchor points in thin or hard-to-reach materials. The tool uses a long-arm, leverage-focused design to reduce hand force, while a full range of mandrels and a generous assortment of rivet nuts cover common metric and imperial sizes. Everything fits into a sturdy storage case so parts stay organized at the jobsite or in the workshop.

How does the GIANTISAN tool reduce effort compared with standard rivet nut pliers?

The 16-inch arm gives more mechanical advantage, so less squeezing force is required to set a rivet nut. Ergonomic grips also reduce hand fatigue during repetitive work. The result is faster installation and a more comfortable user experience for extended jobs.

• 16" long-arm design cuts required hand force roughly in half
• Ergonomic handles for reduced fatigue
• Smoother stroke action for consistent setting

What sizes and components are included, and will they fit my project?

The kit includes twelve mandrels covering common metric and imperial thread sizes plus a total of 316 rivet nuts sorted by size for quick selection. This assortment handles most automotive, fabrication, marine, and household fastening needs where a nut can’t be used from the backside.

• Mandrels: M3, M4, M5, M6, M8, M10, M12, 10-24, 1/4-20, 5/16-18, 3/8-16, 1/2-13
• 316 rivet nuts pre-sorted for immediate use
• Compatible with thin sheet metal, composites, and many soft materials

How durable and serviceable is the tool for professional use?

GIANTISAN constructed the tool from thickened carbon steel with heat treatment plus high-strength aluminum alloy components where appropriate, balancing longevity and weight. Mandrels and user-wear parts are serviceable and can be swapped quickly without tools, keeping downtime low on the job.

• Heat-treated carbon steel for core strength
• High-strength aluminum alloy for reduced weight and corrosion resistance
• Toolless head changes for fast mandrel swaps

What accessories and storage options come with this kit?

All pieces are supplied in a rugged carrying case with molded compartments so mandrels, rivet nuts, and the main tool remain organized and protected during transport. Clear layout and labeling reduces setup time and helps you find the correct size faster on site.

• Molded, impact-resistant carrying box for neat storage
• Sorted trays for quick size identification
• Compact footprint fits work van or tool chest
