Flat Washer Types

Flat washers mainly include ordinary flat washers, elastic flat washers, spline flat washers, cushion flat washers and so on. Different types of flat washers play different roles in various applications, and choosing the right type can improve the performance and service life of fasteners.

Ordinary flat washer is the most basic type of flat washer, mainly made of metal material, used to fill the gap between nuts and bolts, can be used in mechanical equipment, automotive and other fields. Its thickness is between 0.5mm and 10mm, and its service life is relatively short.

Elastic flat washer is a kind of flat washer with elasticity, usually made of plastic or rubber and other materials. It can effectively absorb vibration and noise, and can also reduce the expansion and contraction of machinery and equipment due to temperature changes, usually used in electronic equipment or automobile chassis.

Spline Flat Washers are flat washers with a serrated spline, and can be categorized into two types: external spline and internal spline. External spline washers are usually used for connecting panels, pipes or valves. Internal spline washers are usually used to connect bearings, gears and other components, and can reduce the noise generated by the loosening of the connecting parts.

Cushion flat washers, also known as shock absorbing washers, are mainly made of rubber material and are able to mitigate shocks and vibrations, preventing unwanted noise and vibrations from being generated by machinery and equipment. Cushion washers are commonly used in electronic equipment and automotive shock absorbing systems.
