Kit includes Rivet Nut Tool, Stabilizing Rod, and Qty. 1 each, M-4, M-5, M-6 rivet nut.



This little rivet nut Riveting Tool is the perfect companion for our business. No, Ive never worked on an aircraft but bicycles use M4, M4 and occasionally M6 rivet nuts. There is often no room for a vertical style tool but plenty of room for this horizontal style tool. We now have three, one at every shop. An excellent little tool!

As has been mentioned in other reviews, the washers tended to become distorted. I took a piece of 1/8 flat steel, and cut it to the width of the tool. I drilled a slightly oversized hole for the bolt, placed a washer on the bolt, and added some grease. No more washer problem! This tool works well but is a little slow. For the price, it cant be beat!

This is the ONLY rivnut setting tool to have if you are using Stainless nuts. The simple hand pincher tools are OK if you are using aluminum nuts but this tools is far superior. It has the advantage of being able to be used in tight spaces and you can be very careful in its application and torque. Highly recommended. Aircraft Spruce is a great outlet to deal with and their service is outstanding.

This rivet nut tool broke on my second of 10 holes. The sliding wedge with the slotted hole cracked completely on one side. I give it one star only because it did work on those first 2 rivet nuts
