Flat Pad

1. Flat gasket, mainly made of iron sheet, is generally in the shape of a flat gasket with a hole in the middle

Increase the contact area between screw and machine. Eliminate the damage of the spring pad to the machine surface when unloading the screws. It must be used with a spring pad and a flat pad, with the flat pad next to the surface of the machine and the spring pad between the flat pad and the nut.

2. Flat washers are usually thin pieces of various shapes designed to reduce friction, prevent leakage, isolate, and prevent loosening or distributing pressure. These components are found in many materials and structures and are used to perform a variety of similar functions. Restricted by the material and process of threaded fasteners, the supporting surface of bolts and other fasteners is not large, so in order to reduce the compressive stress on the bearing surface to protect the surface of the connected parts, gaskets are used. In order to prevent the loosening of the connection pair, anti-loose spring washers, multi-tooth lock washers, round nut stop washers and saddle, wave and tapered elastic washers are used.
