With a thin flange and prongs to bite into wood, particle board, plastic, or composite from the blind side, steel T-nuts are used to secure components made of soft materials and allow them to be threaded with a machine screw or bolt. Steel T-nuts are used across industries to join various furniture, cabinetry, woodworking, and other fixtures. Superior Components supplies a wide range of standard and metric steel T-nuts, including multiple prong variations, barrel lengths, and custom features to meet your specific needs.

What are Steel T-Nuts?

Steel T-nuts, also called tee nuts or blind nuts, are threaded inserts that provide a strong, reusable machine thread for soft materials while sitting flush to the surface for a reliable joint. These specialized fasteners feature a flat, circular flange, a central, internally threaded barrel, and protruding prongs to “bite” into the material and deliver a secure, semi-permanent hold.

Benefits of Steel T-Nuts in Fastening Applications

By embedding securely into various light materials, steel T-nuts offer a cost-effective solution for repeated assembly and disassembly across applications, providing benefits such as:

Provides excellent tensile strength and torque tolerance to support heavy loads
Features sharp prongs to prevent spinning and pull-out when a bolt is tightened from the other side
Sit level with or below the surface of the material to prevent protruding hardware
Can be unbolted and reattached repeatedly without degrading the connection point
Highly resistant to loosening from mechanical vibrations
