Made of 304 Stainless Steel 18/8 with black coating outside which is superior to regular stainless steel and any zinc plated fasteners, provides better strength and corrosion resistance in bad environments like high temperature, cold weather and high humidity areas without the need for time consuming and costly maintenance
Application: provide a bearing surface for fastener load distribution or acts as a spacer.
Flat washer can be used to disperse the pressure of the bearing surface of the fasteners such as bolts to protect the surface of the connected part. It can reduce friction, prevent leakage, isolating and loosening
