Product Description
Electrogalvanizing washer, the common shape of a flat washer is a
hole in the central. The pore size specifications according to

customization. It has many standard: DIN125 DIN9021 F436, ect.
Plain washers, which spread a load, and prevent damage to the
surface being fixed, or provide some sort of insulation such as
electrical
Flat washer is generally used in fitting a soft texture, is a hard
and brittle, its role is largely increase the contact area,
dispersing pressure, prevent the quality of a material soft crush.
Flat mat is: 1, increase the contact area of the screw and machine
2, eliminate the trampoline at the time of discharge screw damage
on the surface of the machine.Must be: when using a flat pad, spring pad flat pad close to the
surface of the machine, spring cushion between the plain washers
and nuts. Flat pad is in order to increase the screw surface.Spring pad to prevent screw loosening, force when a certain amount
of buffering effect. Although flat mat can do sacrifice pad.But more often is used as supplement pad or flat mat.And the spring pad a lock.Such as the workpiece hole diameter value
and the screw diameter is too large when not using a flat mat or
direct use of spring washers, will not only harm the artifacts.
Flat washer is generally used to distribute the load of a threaded
fastener, such as a bolt, scres or nut. Other uses are as a spacer,
spring (wave washer), wear pad, preload indicating device, locking
device, and to reduce vibration , rubber washer. Washers usually
have an outer diameter (OD) about twice larger than their inner
diameter (ID).
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.
