81 Piece Metric Nutsert Gun and Rivet Nut Kit

Install metric nutserts quickly and cleanly with this 81-piece Teng Tools tray. The hand-operated gun accepts four included mandrels — M3, M4, M5, and M6 — so you can pull the most common metric threaded inserts without switching to a different tool.

Inside the red plastic TT1 tray you will find 20 M3 nutserts, 20 M4 nutserts, 20 M5 nutserts, and 15 M6 nutserts, giving you 80 fasteners ready to use straight out of the drawer. Each piece sits in a molded pocket that keeps the tray neat and makes it obvious when stock is running low.

The tray format is what sets this kit apart from loose rivet nut sets. Drop it into a Teng Tools roller cabinet or top box and it lines up with the rest of your TT1 collection, turning an entire drawer into a labeled station for threaded-insert work. No rattling bags, no mixed sizes, no wasted time.

Because the gun is hand-operated, there is no compressor, battery, or cord to manage. Take it to the vehicle, up a scaffold, or across the shop floor — wherever you need a captive metric thread in sheet metal, tubing, or thin-wall material.

Total tray weight is 1043 g. That keeps the drawer easy to slide and the kit comfortable to carry when the job is not at your bench.

Whether you are fitting accessories to an off-road rig, securing ductwork in an HVAC run, or building a custom bracket on the fabrication table, this tray puts the gun, the mandrels, and a healthy stock of nutserts in one place so you can focus on the work instead of the tool hunt.
