1. Product Description
SEA Flat Washer, 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 washers are usually thin pieces of various shapes, used to
reduce friction, prevent leakage, isolate, prevent loosening or
disperse pressure. Many materials and structures have such
components for performing various similar functions. 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.
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.
