KOOPOOL 16" Rivet Nut Tool Kit – 14 Mandrels & 170 Nuts, 16" Double-Compound Lever, Quick-Swap Mandrels

The KOOPOOL 16" Rivet Nut Tool Kit is a heavy-duty hand rivet-nut setter with 14 quick-swap mandrels and 170 assorted rivet nuts to install blind rivet nuts in metal and composites.

Built to speed up professional and hobby projects, this 16-inch, double-compound rivet nut tool reduces the effort needed to set large nutserts and arrives as a complete kit covering both metric and SAE sizes. The tool combines a quick-change mandrel system, an adjustable visible stroke for repeatable pulls, and a broad assortment of fasteners so you can work on cars, trailers, metal frames, furniture, and general fabrication tasks without stopping to hunt for parts or extra tools.

How does the quick-swap mandrel system save time on the job?

The mandrel change mechanism lets you switch sizes in about five seconds with no disassembly: press the sleeve, twist the mandrel out, and screw in the replacement. That minimizes downtime and keeps momentum during multi-size installs.

• Press-and-twist sleeve for tool-free mandrel removal
• Fits both metric (M3–M12) and SAE mandrels (6-32 to 1/2-13)
• Keeps projects moving without loosening bolts or disassembling the tool

Will the adjustable stroke improve consistency and prevent damage?

The visible stroke scale lets you set and repeat the exact pull length, which reduces over-compression and helps protect thin panels and softer materials. Consistent stroke settings deliver uniform rivet nut deformation for better clamping and fewer scrap pieces.

• Clear scale visible during use for repeatable pulls
• Helps prevent over-pulling and workpiece distortion
• Useful when working with aluminum, steel, or stainless sheet

How much effort does the 16" double-compound design save?

The extended 16-inch handles use a double-compound leverage system that cuts physical effort by up to half compared with many 14-inch tools. That extra mechanical advantage is especially helpful when installing larger rivet nuts like M12 or 1/2"-13 in tougher materials.

• 16" handles reduce hand force required by up to 50%
• Enables single-operator installation of larger rivet nuts
• Comfortable grip and longer reach for awkward placements

What comes in the kit and how durable is the construction?

The kit supplies 14 mandrels covering a full range of metric and SAE sizes plus 170 rivet nuts in assorted diameters so you can tackle most automotive or fabrication tasks right away. Components are heavy-duty: the tool body is high-strength carbon steel with a black-oxide finish and the mandrels are heat-treated CR-V for lasting wear resistance.

• 14 mandrels for M3–M12 and 6-32 to 1/2"-13 sizes
• 170 assorted rivet nuts to start work immediately
• Carbon-steel tool with black oxide and heat-treated mandrels
• Backed by a 2-year warranty and responsive customer support

Who is this for? The KOOPOOL 16" Rivet Nut Tool Kit suits professional mechanics, metal fabricators, renovators, and serious DIYers who need a ready-to-use, durable rivet-nut solution. If you frequently install blind nuts in sheet metal, structural frames, or aftermarket parts, the combination of quick-change mandrels, adjustable stroke, and a full assortment of nuts will save time and reduce physical strain compared with smaller or single-size tools. Note: fully insert the mandrel before use to ensure correct installation and the best results.
