View Catalog Page in PDF format

These general purpose inserts will work on any metal part over .030 inch thick, even in solid materials. When properly installed and used, they provide excellent resistance to pull-out and torque-out. They protrude only .015 inch above the surface and can be made completely flush by slightly countersinking or dimpling the mounting hole. The material for these inserts is plated steel.

Use our Rivet Nut / Insert Nut Installation Tools (Part No. 659-size) to install these inserts.

Note: The part being fastened (the removable part) must bear directly against the rim of the insert. If the removable part has an over-sized hole or is a soft material such as fiberglass, a washer should be used between the insert and the part to provide a bearing surface directly against the insert.

Worked ok, but larger shoulder would have been better.


Was installing into a hole drilled into round tubing and a slight larger shoulder would have made the installation more secure and easier to keep nutsert aligned properly during installation..

Worked well


Replaced existing nutserts that were stripped out. Worked well w Pegasus Economy Nutsert tool. Glad I bought extras.

I use these in several sizes to mount panels, etc. on the race car. They are great when you can't get a wrench on a nut. I use them for my splitter, dash panels, shifter plates and for the cover over the fuel cell.
