WelderElite Dual-Function Rivet Nut Tool Kit 14" — 405-Piece Rivet & Nutsert Set with 15 Mandrels, 5 Nozzles

WelderElite Dual-Function Rivet Nut Tool is a 14" hand tool that installs blind rivets and rivet nuts, supplied with 405 fastening pieces plus mandrels and nozzles for metric and imperial sizes.

Compact and built for workshop or on-site use, this kit combines a heavy-duty hand riveter with a wide selection of nutserts (rivet nuts) and blind rivets so you can fasten thin materials, panels, and assemblies without access to the backside. Everything is organized to support common metric and imperial thread sizes along with the correct mandrels and pulling nozzles — reducing trips to the hardware store and simplifying many retrofit or repair jobs.

Which fastener sizes are included for metric and imperial projects?

The kit covers a broad range of threaded nutserts and blind rivets to handle most vehicle, appliance, and fabrication tasks. Metric nutserts range from M3 through M12; imperial (UNC/UNF) sizes cover popular 6-32 up to 1/2-13. Blind rivets span 1/8" to 1/4" diameters for typical sheet joining.
