KOOPOOL 16-inch Rivet Nut Tool Kit — 14 Mandrels & 170 Nuts, Quick-Swap Long-Leverage Handles

The KOOPOOL 16" Rivet Nut Tool Kit is a complete hand-installation system with long-leverage handles, 14 quick-swap mandrels, and 170 assorted rivet nuts for reliable blind nut fastening in metal and composites.

This professional-grade kit pairs a double-compound 16-inch hand tool with a wide selection of metric and SAE mandrels plus assorted rivet nuts so you can install threaded inserts quickly without a hydraulic press. The tool’s quick-swap mandrels, adjustable stroke with visible scale, and heat-treated components bring repeatable results for automotive repairs, metal fabrication, cabinetry, and field service work.

How does the quick-swap mandrel system speed up my projects?

Changing mandrels takes seconds: press the sleeve, twist out the old mandrel, and screw in the next one. This tool-free system eliminates the need to disassemble the mechanism or carry extra wrenches, which keeps workflow steady when you switch sizes frequently.

• Press-and-twist sleeve release for tool-free swaps
• Compatible with both metric (M3–M12) and SAE (6-32 to 1/2-13) mandrels
• Reduces downtime between fastener size changes

What benefit does the adjustable stroke and visible scale provide?

The visible stroke scale lets you set and repeat the correct pull length, minimizing over-compression of the rivet nut and protecting the workpiece. That control helps produce uniform, secure installs across batches and prevents ruined fasteners or stripped threads.

• Clear stroke indications for consistent results
• Prevents over-pulling on thin or soft materials
• Makes repeat installs predictable across multiple holes

Why choose a 16" double-compound handle over a shorter tool?

The long double-compound handles increase mechanical advantage so you need up to 50% less effort versus typical 14" tools. This leverage is especially useful when setting larger rivet nuts such as M12 or 1/2"-13 into aluminum, steel, or stainless steel where higher pull force is required.

• 16" length and compound linkage reduce hand strain
• Better control when installing larger-threaded inserts
• Suitable for tougher materials and frequent use

What’s included and how durable is the kit?

The set ships with 14 mandrels covering metric and SAE ranges plus 170 assorted rivet nuts to cover common repair and fabrication needs. Key components are heat-treated or made from high-strength carbon steel with a black oxide finish to resist wear and corrosion, and mandrels are CR-V for longevity.

• 14 mandrels (M3–M12 and 6-32 to 1/2-13) and 170 rivet nuts
• High-strength carbon steel body with black oxide finish
• Heat-treated CR-V mandrels and a 2-year warranty

Who this kit is for: The KOOPOOL 16" Rivet Nut Tool Kit is aimed at mechanics, metalworkers, DIYers, fleet technicians, and assembly professionals who need a portable, reliable blind-nut installer. If you frequently fasten threaded inserts in sheet metal, brackets, panels, or tubing and want quicker mandrel changes, measurable stroke control, and reduced hand effort for larger nuts, this kit provides the parts and durability to keep jobs moving.
