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.

The role of the flat washer:
1,Increase the contact area between the bolt and the machine.
2,To eliminate the damage to the surface of the machine when the spring washer is unloading the screw. When using must be a spring washer a flat washer, the flat washer next to the machine surface, the spring washer between the flat washer and the nut.

 

Application Range:

 

1. Machines, auto industry, roads,

2. Bridges, tunnels, urban railway systems,

3. High speed railways, watercrafts, thermal power,

4. Wind power, nuclear power, petrochemical, aerospace,

5. Steel roof constructions and so on.
