Lock Washer Dubai

Star / Serrated Washers are locking washers with teeth or serrations designed to prevent loosening of fasteners under vibration and load. They bite into the surface of the assembly, creating additional friction and resistance to rotation. Manufactured to ASTM and DIN standards, they are available in internal, external, and combination serration types. These washers enhance joint security in dynamic or high-vibration environments. They are widely used in machinery, automotive, aerospace, electrical assemblies, and heavy engineering.
