Rohs/Reach Compliant/Halogen Free Compliance  Function with double washer: Washers are divided into flat washers and spring washers. Due to the small contact area with the base after the screws are tightened, adding flat washers can increase the pressure bearing area of the base, and tightening will not cause damage to the base or silk. The spring washer increases the stress of the screw buckle and tightens the screw tightening effect.

Replaces three parts: screw, flat washer and helical washer, in many applications. The unique washer on this assembly combines the tension generating characteristics of a spring washer with the locking tension of the helical washer to increase shock absorption and vibration resistance.
