Squaresert Threaded Insert

High-quality Squaresert Threaded Insert

Squaresert Threaded Insert The Avdel Squaresert is a steel threaded insert with a square body, providing very high torque-to-turn and pull-out performance in all materials. The Squaresert rivet has a large flange to increase the load bearing surface allowing the Squaresert to be used in thin sheet materials.
