WelderElite Dual-Function Rivet Nut Tool 14" with 405‑pc Kit — Blind Rivet & Nutsert Installer, 15 Mandrels

WelderElite Dual-Function Rivet Nut Tool is a 14" hand tool that installs both blind rivets and rivet nuts, supplied with a 405-piece consumable kit and 15 mandrels for metric and imperial fasteners.

This kit combines a robust dual-purpose rivet gun with a comprehensive assortment of nutserts, blind rivets, mandrels and nozzles so you can tackle automotive repairs, metal fabrication and general assembly without searching for extra parts. The tool converts between pulling blind rivets and setting threaded rivet nuts, and the case contains multiple sizes for common metric and imperial work.

How does the tool switch between rivet and rivet-nut modes?

The WelderElite gun converts by changing mandrels and attaching the appropriate nosepiece. Swapping components is tool-free for most changes and each mandrel aligns with a matched rivet-nut size to ensure correct grip and compression.

• Change mandrels to match metric or imperial nutserts (M3–M12 and 6-32–1/2-13).
• Swap one of five blind-rivet nozzles for pull-type rivets (φ3.2–φ6.4 mm).
• 14" lever arms provide leverage for manual operation without extra power tools.

What sizes and quantities are included in the 405-piece kit?

The kit supplies both metric and imperial threaded nutserts, a full set of blind rivets, and 15 mandrels plus nozzle heads so you can begin work immediately. Quantities vary by size, prioritizing the most frequently used sizes for general maintenance and fabrication.

• Metric nutserts: M3–M12 (most sizes 30 pcs; M10 & M12 fewer for specialty uses).
• Imperial nutserts: 6-32 through 1/2-13 with counts tuned for common sizes.
• Blind rivets: five diameters, 20 pieces each for reliable stocking.

What materials and projects is this kit best suited for?

Use the WelderElite kit on thin-gauge steel, aluminum, sheet metal, plastic panels and light structural assemblies where blind or threaded fasteners are needed. It performs well for auto trim, appliance repair, HVAC ducts, metal furniture and DIY projects where access is limited to one side.

• Blind rivets for joining overlapping sheet metal or panels from one side.
• Rivet nuts (nutserts) where a strong threaded anchor is needed in thin material.
• Manual 14" tool offers control for delicate materials and avoids over-torque.

Who is this for? This WelderElite kit suits mechanics, fabricators, installers and serious DIYers who need a portable, all-in-one rivet and nutsert solution with a wide size selection. If you frequently install threaded anchors or work where only one side of a joint is accessible, this pack delivers the parts and mandrels to cover most on-site fastening needs without buying extra components separately.
