DIN125A Flat Washer,M5,Grade 4.8,Carbon Steel,Round head,Zinc Plated
Product Description:
First Standard flat washer, smooth surface, galvanizing process, moisture-proof and anti-corrosion, that is to say, not easy to rust.
Surface treatment is smooth, burr-free, excellent workmanship, thickening treatment, long service life.
For function:
DIN125A 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
