Made of 18-8 stainless steel, these rivet nuts withstand water, mild chemicals, and outdoor conditions better than zinc-plated steel nuts. A ribbed body grips surrounding material to hold them in place, keeping them from spinning as you tighten screws.

Originally designed for Formula 1 racecars, these titanium rivet nuts are the best choice when you need a high strength-to-weight ratio—they're 40% lighter than steel nuts.

Our most twist-resistant round rivet nuts, these have both a ribbed body and wedges under the flange that bite into material to prevent spinning when tightening a screw. With a thick body for heavy duty applications, they match the strength of Grade 5 and Class 8 screws.

A PVC foam seal under the flange keeps liquids and gasses from leaking between the nut and the surrounding material.
