Disc Spring Lock Washer, JIS B 1251, Class 1 (for Screws, for Heavy Loads)

Disc Spring Lock Washer, JIS B 1251, Class 1 (for Screws, for Heavy Loads)

This part has spring counter-force comparable to tightening axial force of bolts and prevents thread loosening caused by vibration and shock. It is possible to obtain a stable tightening axial force without causing fatigue to the tightening material due to the low pressure applied to the bearing surface.
