Multi-Grip Rivet Nut Installation Tool Set Pre-Bulbed Shank Flat Head Threaded Insert Nut Plus Nuts Assortment Kit Cross Rivnut for Construction Industrial (1/4-20(Plus Nut Tool-6pcs))

used this bad mambajamba today, this sucker really works great! my boss Adam Kern said he HIGHLY recommends this, great tool, quality purchase, and also...great value! will buy more in different size from this seller!!!

This was a perfect solution to reattach hinges to a screen door where the sheet metal screws finally stripped out. The trick was to get the biggest rivnut that would fit on the edge of the door, which in my case was the M4 (4 mm). The original stripped out holes were drilled to accept the multigrip rivnut, which appeared to be a better solution than a standard one. The base of the tool didn't quite fit in the recess of the door edge so it wasn't flush against the rivnut, but that was easily remedied by inserting a few washers between them. I was concerned about breaking off the screw as was reported in other reviews. So, I sacrificed one rivnut to observe its collapse outside of the "blind hole", while counting the number of turns required to collapse it. It really doesn't take much torque, and after the first one or two you get a good feel for when it's fully tightened. Cap screws were used as they have a "built-in" washer and minimal height so as not to interfere with the door closure. Finally, the rivnut flange thickness was a concern at first, because the hinge plate would no longer lay flush onto the door edge , but it was negligible at about 1 mm so the door still fit and works flawlessly. The kit only had six rivnuts so I bought an extra pack, so this entire project only cost less that $30 vs a new Pella door for hundreds (assuming I could find one...).

Used this to fix a recurring problem with the door air cylinder on our LTV Unity MB. The pivot pin fot yhe air cu;inder keeps falling out letting the door to swing out against the coach. This pin and Rivet Nut were never installed into the door frame properly from the factory and is a known problem in the LTV community. Most people are putting up with it or ordering replacent air cylinders and pins over and over, but the problem is the rivet nut was just press fit into the hole. I chose this set because my hole has become oversixe and the wings formed during compression completely removed any excess play side to side and worked beautifully. Very easy instuctions to follow and I have posted this on the LTV Bulletin board as an simple and easy fix Well worth the money.

Needed 15 rivet nuts for a single project, so I thought this would be fine over the $80+ big tool I'd never use again. Not sure how but the inner screw got stripped after 8 rivet nuts and I couldn't complete the project. Complete waist of time and money.

I have used this tool to install over 150 riv-nuts for new shop project with no problems as of this review. The pulling mechanism has been holding up, however, there are two fine threaded caps on either side that like to work themselves loose. The step drill is junk, never worked out of the box. A word of advice, the tool needs to be in a stable position with no side pressure. Also, if using a impact drill, do not over torque. Update 02/14/26 - This tool still going strong. I purchased three just in case it breaks, but no problems. I tightened the caps with no loose parts. Over 300 riv nuts installed.

Nice tool… could use the bolt!! This will help me install my gas can.

I have another version of this tool and this new one is the BOSS. I Love it, i use my makita to set the nuts and it works so easy and fast. I wish I bought this one a long time ago instead of struggle with my last one. Great item

The rivet nut worked great for a ladder rack install in my truck bed but the tool was done after one use. I greased everything up and followed all directions but the threads on the tool were shot. I had to use a bolt, washer and socket to install the rest of the rivet nuts and was actually much easier than using the tool.
