DOUBLE COIL
LOCK WASHER

The double coil helical spring lock washer is utilized for soft joints, including wooden pole assemblies that are significantly impacted by contraction and expansion from temperature changes. The double coil offers the necessary travel to sustain a strong clamping force and prevent loosening resulting from corrosion and vibration. It does so by maintaining tension on the bolt in these assemblies. Also, the double coil spring lock washer is made with an inside oversized dimension.

These double coil lock washer products are available in plain, hot-dipped galvanized, and mechanical galvanized finishes. They have been used in a multitude of assembly applications across various industries.
