Disk Spring Lock Washer, JIS B 1251, Class 2 (for Caps, for Heavy Loads)

Disk Spring Lock Washer, JIS B 1251, Class 2 (for Caps, for Heavy Loads)

Screw has a spring counter-force when compared to the tightening axial force of bolts. The spring 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 as a result of the low pressure applied to the bearing surface.
