Plain Washers , DIN 125 Stainless steel SS 304, SS 316 washer
1.Product Description
Increase the contact area flat pad, spring pad is used to prevent loose when spring pad to pay attention to the direction of the opening, or else from the anti-loose little effect.
Flat pad can protect the surface of the contact surface elastic pad lock is mainly to make there is always a preload between fasteners within its elastic deformation range
The main effect is to increase the gasket bolt or nut contact area with the surface of the part, the part surface to prevent wear out; the second is made of spring washers, locking play a role.
Also note that the strength and thickness of the washers have certain requirements.
The main effect of a flat washer to protect the surface fastener to prevent scratching the surface when the bolt nut tightening; spring pad is anti-loose, but some important connections, such as pressing friction generated mainly rely on local transmission of power is not using a spring pad, with reduced rigidly anti easy to trouble.
1, spring washer role is to tighten the nut after nut spring washer to a stretch,
Against the nut, it is not easy to fall off. The basic action of the spring, then tighten the nut after nut a force, increasing the friction between the nut and bolt.
2, generally do not use elastic pad flat pad, (except to protect fasteners and mounting surface with a flat surface when considering pad and spring washers).
3, flat washers generally used in the connecting member is a soft texture, a hard brittle texture, and its main role is to increase the contact area, spread the pressure, prevent the soft texture of crushed.

3.Application
1, the surface gloss
2, excellent resilience
3, excellent sealing effect
4, excellent weather resistance
5, good material stability
6, can be customized non-standard models
4.Advantage
Flat pad is to increase the role of the contact (bearing) area, dispersion, reduce stress and nut is tightened between the parts, due to the tightening force to prevent local compressive deformation, is to enhance the overall tightening effect. Some of the larger load bearing areas, but also thick flat pad, thick flat pad.
