RS PRO BZP Spring Steel Lock Washer


From the trusted RS PRO brand, this external tooth lock washer is ideal for added security in fixings and fastenings. They function in the same way as a standard washer, by distributing the load of a bolt against a surface material, but have a locking action that prevents turning of the fastener, meaning there is less chance of the fixing loosening over time or under repeated stress. As such they are commonly used wherever vibration is a factor.

There are various sizes available;


• 526-574 is an M3 internal tooth shakeproof washer;• 526-596 is an M4 internal tooth shakeproof washer;• 526-603 is an M5 internal tooth shakeproof washer;• 526-619 is an M6 internal tooth shakeproof washer;• 530-129 is an M8 internal tooth shakeproof washer;• 530-135 is an M10 internal tooth shakeproof washer;• 530-141 is an M12 internal tooth shakeproof washer;• 193-3453 is an M16 internal tooth shakeproof washer;• 193-3454 is an M20 internal tooth shakeproof washer;• 193-3455 is an M24 internal tooth shakeproof washer
