Flat washer GOST 11371-78 is used in combination with nuts to complete bolts, screws and studs to make reliable detachable threaded connections. GOST 11371-78 is placed under the bolt head to reduce the pressure on the fastener and increase the bearing area of the fastener itself. This prevents surface deformation, increases the attachment area, holds the element on brittle base materials and prevents the fastener from loosening.

Fastener group GOST 11371-78

Depending on the material of manufacture according to GOST 11371-78, flat washers are divided into various fastener groups:

High-strength fasteners
Brass fasteners
Stainless steel fasteners
Polyamide fasteners
Copper fasteners
Aluminum fastener

Materials for the manufacture of washers

The material of the washer is GOST 11371-78:

Steel
Brass
Polyamide
Copper
Aluminum
Stainless steel A2, A4, A5

Where and how flat washers of GOST 11371-78 are used

GOST 11371-78 is a washer that is required in all structures, no matter what materials the structure consists of: wood, metal or any other. The scope of use of this washer rather depends on the environment in which it will be used.

Galvanized steel is a good protection against corrosion if the fastener is to be used in an aggressive environment.
Brass is used if the system is subjected to frequent dynamic, vibration loads.
Stainless steel allows the fasteners to be used at significant temperature changes and in aggressive and humid environments.
Polyamide hardware withstands mechanical shocks, does not crack or break at the permissible load factor.
