SS316 SS304 316L Plain Color Steel Flat Washer A2 -70 Flat Metal Washers
1.Product Description
Stainless steel A2-70 cushion, used to prevent loosening, cushion
can protect the contact surface of the elastic pad lock mainly in
order to keep a pre-tightening force between fasteners in its
elastic deformation range.
The main function of the flat cushion is to increase the contact
area between the washer bolt or nut and the surface of the parts.
At the same time, the spring washer plays a locking role.
When using flat washer, we should pay attention to the strength and
thickness of the washer. The main purpose of flat washer is to
protect the surface fasteners and prevent scratching. Spring
cushion is anti-loosening. But some important connectors, such as
compression friction, mainly rely on local power transmission, not
using spring cushion, with R. Strict compliance with requirements
will not cause unnecessary trouble.

5.Advantage
Reduce pressure.
Flat gaskets are usually thin pieces of various shapes, used to
reduce friction, prevent leakage, isolate, prevent loosening or
pressure dispersion. Many materials and structures have such parts
to perform similar functions.
Due to the material and process limitations of threaded fasteners,
the supporting surfaces of fasteners such as bolts are not large,
so gaskets are used to reduce the compressive stress of the bearing
surface to protect the surface of the joints.
