Product Description

Flat washers are also known as flat washers. They are mainly stamped with iron plates. They are generally flat washers with a hole in the middle. This hole size specification is generally based on customer requirements.
There are 9 flat washer standards in China, which were approved for release from 2000 to 2002 GB/T 97.3-2000, GB/T 5286-2001, GB/T95-2002, GB/T 96.1-2002, GB/T 96.2 -2002, GB/T97.1-2002, GB/T97.2-2002, GB/T97.4-2002 and GB/T5287-2002 flat gasket standards.
According to the performance level of flat washers, I recommend using materials:
For the 100HV class available with ST12, ST13 and Q235, Q215, Q195, etc., the surface hardness can reach about 110HV;
For the 140HV class with optional 08F, 08Al and 10, 10F, etc., the surface hardness can reach about 140HV;
For the 200HV and 300HV grades, 45, 50, 60, 70 or 65Mn steels should be used. They can be quenched and tempered by heat treatment to 200-300HV and 300-400HV technical requirements.

The Role of Flat Mat

1. Increase the contact area between the screw and the machine.

2. Eliminate damage to the surface of the machine when the spring pad is unloaded. When used, it must be a spring pad and a flat pad. The flat pad is facing the surface of the machine. The spring pad is between the flat pad and the nut.

Flat pad standard

National standards are different.
Here is the United States flat pad standard:
