PTFE Round Plain Washer / Teflon Flat Washer / Flat Washer Come With Bolts And Nuts
The flat pad, mainly stamped out of an iron plate, is generally shaped as a flat washer with a hole in the middle.
The Basic knowledge of flat washer:
Flat washers are usually thin parts of various shapes used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. Such parts are found in many materials and structures and are used to perform a variety of similar functions. Threaded fasteners by the material and process limitations, bolts and other fasteners are not large support surface, so to reduce the compressive stress on the bearing surface to protect the surface of the connected parts, its use of washers. To prevent the connection of the vice of the loose spring washers and multi-tooth lock washers, round nut stop washers and saddle, waveform, conical elastic washers.
Flat washers are mainly used to reduce the compressive force, when there are parts of the tightening axial force is very large, easy to make the gasket pressed into the disc, then you can change the material and improve the hardness to solve.
