Split Lock

A split lock washer, also known as a helical lock washer, is a coiled, hardened, split circular washer with a slightly trapezoidal wire section. A split lock washer applies greater bolt tension per unit of applied torque and provides a hardened bearing surface, creating more uniform torque control. Split lock washers provide uniform load distribution, and resist loosening caused by vibration and corrosion. Available and ready-to-ship in a variety of sizes and finishes.

Heavy Split Lock Washers:  Similar to a regular split lock washer, but with a greater outside diameter and thickness. The increased bearing area makes this suitable for applications involving higher tightening torques.

High Collar Split Lock Washers:  A Hi-Collar washer is thicker and has a smaller outside diameter than a regular split lock washer. Designed for use with smaller head screws, particularly sockets. 

Medium (Regular) Split Lock Washers:  The most commonly used split lock washer. Used for general purpose applications and is the preferred lock washer for use with hardened bearing surfaces.
