The "Split" in the helical spring lock washer absorbs the initial driving torque and visually closes under normal bolt loading. ITW Shakeproof Industrial's Helical Spring Lock Washers are trapezoidal in shape, which contributes to the further deflection and compression of the washer under load. 2019-12-9 · JF Engineering is the industry leader in offering what is undoubtedly the most

They are relatively lightweight, producing quite low preload forces. Split washers or helical spring washers, work in a similar way to a wave washer. Some claim that they provide a locking action by digging into the bearing faces but, in reality, these are typically too hard for this to produce any noticeable effect.

How does helical spring lock washer work? It contains a split section which is designed to absorb the driving torque. The reduction of tension causes bolt loosening. When this happens, using helical spring washer is essential since this delivers
