Double Coil Spring Lock Washers

Double coil lock washers, also known as helical spring split lock washers, are typically used in wooden pole line assemblies that have to account for substantial expansion and contraction due to weather. The double coil can maintain effective clamping force and resist loosening caused by vibration and corrosion by keeping tension on the bolt.
