Teeth Nut

Teeth Nuts are self-locking nuts with serrations or teeth that grip the mating surface to prevent loosening under vibration. They can feature internal or external serrations, often combined with a flange for greater load distribution. Manufactured to ASTM and DIN standards, they are available in carbon steel, stainless steel, and brass. Their locking action ensures secure fastening without the need for additional lock washers. They are commonly used in machinery, automotive, railways, electrical fittings, and vibration-prone assemblies.
