Flat Spring Washer for Cap- JIS B, Type 2, Heavy Load

Heiwa Hatsujo

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.
