Product Description:
What is flat washer?
It is a part of a finger pad between the connector and the nut. Generally flat metal rings are used to protect the surface of the jointed parts from scratch by nuts and to disperse the pressure of nuts on the jointed parts.
And flat washer, as hardware products, widely used, have many advantages:
1. Increase the contact area flat pad,however 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.
2.Used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure.Due to the material and process limitations of threaded fasteners, the supporting surfaces of bolts and other fasteners are not large, so gaskets are used to reduce the compressive stress of the bearing surface to protect the surface of the joints.
3.Flat washer 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.
4.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,
