PRODUCT OVERVIEW
This 3/4 HDG double coil lock washer is an industrial fastening component used beneath a nut or bolt head to help maintain tension in assembled joints. A double coil lock washer is formed from round wire shaped into two coils, giving the washer a spring-like configuration that can accommodate movement in fastening applications.
Compared with a single-coil washer, the double-coil design is commonly used where additional movement in the joint may be beneficial. This type of washer is often found in applications where vibration, material movement, corrosion exposure, or shrinkage may affect fastener tension over time.
