Tab Washers
A tab washer is a flat washer with one or more tabs that can be bent to lock it in place against a bolt or nut. These tabs prevent rotation and help keep fasteners secure, especially in high-vibration or moving applications.
It is widely used for secure fastening and anti-vibration purposes in industrial assemblies to prevent loosening over time. The material can also be hardened or tempered as per required hardness specifications.
