The three weld points on these metric hex nuts create a secure hold on a steel surface. Weld them to sheet metal or thick steel surfaces to add strong, permanent threads. They stand up to high torque and pull force better than rivet nuts. Made of uncoated steel, there’s minimal prep required to weld them to uncoated steel surfaces. All have a collar pilot that guides the nut into the hole, holds it in place while welding, and protects the threads from weld spatter.

You can weld these nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold. They have a collar pilot that assists alignment and prevents welding spatter from getting into threads.

Irregularly shaped threads in these nuts form a tight grip, preventing screws from backing out in vibration-heavy environments. These weld nuts stand up to high torque and pull force better than rivet and press-fit nuts, making them the strongest way to add threads to sheet metal. They can be welded onto thick metal surfaces, too. To protect their threads from deforming, these nuts have three projections that concentrate your weld and create room for heat to dissipate. A collar pilot guides the nut into the hole, lightly holds it in place during welding, and protects threads from spatter.

These nuts are designed for use with Grade 2 or Class 6 screws. Use screws that have a similar strength rating to avoid stripping threads during installation. Screw-locking threads require high torque for fastening and unfastening, so you may need an impact wrench to remove screws.
