Washers

ITW Shakeproof Group Lock Washers

Historically, ITW Shakeproof Group’s Helical Spring Lock Washers have been among the most widely used anti-loosening components on the market.

The “Split” in the helical spring lock washer absorbs the initial driving torque and visually closes under normal bolt loading. ITW Shakeproof Group’s Helical Spring Lock Washers are trapezoidal in shape, which contributes to the further deflection and compression of the washer under load.
