Rubber Nuts

Rubber Nuts (also known as well nuts or expansion nuts) are versatile, vibration-resistant fasteners designed for applications where a secure, removable threaded anchor is needed but access to the backside of the material is limited or impossible. They combine a threaded brass or steel insert with a flexible rubber sleeve that expands when the mating screw or bolt is tightened.

Hanson Rivet carries Rubber Nuts in multiple thread sizes, grip ranges, and sleeve materials to suit a wide range of fastening needs. Whether you need standard well nuts or specialty expansion inserts, you can find them here for reliable, repeatable performance.
