DIN 93:1974 Washer

DIN 93:1974 Single Tab Lock Washer uses one bendable tab to provide mechanical locking and prevent a nut or bolt from rotating loose in vibration-prone conditions. During installation, the tab can be bent against the locked part or fastener side, creating a visible locked state.

It is commonly used in mechanical transmissions, shaft-end fixing, equipment maintenance, and industrial connections requiring dependable loosening prevention. Compared with elastic locking parts, a tab washer emphasizes deformation-based locking and is suitable where a defined locked position is needed.

The model can be selected by thread size, tab direction, material, and surface treatment to meet repair, corrosion protection, and safety inspection requirements.
