Nord-Lock Small OD Locking Washers, Carbon Steel

Click for a larger picture of Nord-Lock Small OD Locking Washers, Carbon Steel

Brand: NORD-LOCK

Nord-Lock washers are designed to prevent threaded fasteners from loosening. Each Nord-Lock consists of two washers with interlocking faces. The cam angle on the interlocking faces is greater than the thread pitch angle, effectively increasing the torque required to loosen the fastener. Mild carbon steel with zinc flake coating for corrosion resistance. Each is enough for one bolt.

The NLCS Series washers have a small OD that matches the head OD on standard socket-head cap screws ("Allen" screws). This allows their use in a recessed hole that is just large enough to accept the "Allen" head. Note that this size is not appropriate for use under a nut (use the larger OD Nord-Lock NLCS-SP Series under a nut or hex bolt head). Install a Nord-Lock in place of a flat washer (using a Nord-Lock with a flat washer will defeat the locking action).
