DIN125 Customized Sizes For General Industries High-Quality Stainless Steel 304/316 Metal Flat Washers

The flat washer is mainly used to reduce the pressure. When the axial force of some parts is very large, it is easy to make the washer into a disc shape. At this time, it can be solved by using materials and improving the hardness.

The locking effect of the spring washer is general, and the important parts are used less or not as much as possible, and the self-locking structure is adopted. For the spring washer used for high-speed tightening (pneumatic or electric), it is better to use the washer with surface phosphating treatment to improve its wear reduction performance, otherwise it is easy to burn or open the mouth due to friction and heat, or even damage the surface of the connected parts. For sheet joints, spring washer construction shall not be used. According to statistics, spring washers are used less and less in cars.

Because of the large and even locking force, the connection tooth shape of the elastic washer with tooth shape is more used in the automobile industry, while the interval tooth shape is less.

Specification

Application

Flat washers are usually thin pieces of various shapes, which are used to reduce friction, prevent leakage, isolate, prevent loosening or dispersing pressure. This component is found in many materials and structures to perform various similar functions. Limited by the material and process of threaded fasteners, the bearing surface of bolts and other fasteners is not large. Therefore, in order to reduce the pressure stress on the bearing surface and protect the surface of connected parts, washers are used. In order to prevent the looseness of the connection pair, the spring washer and the multi tooth lock washer, the round nut stop washer and the saddle shaped, wave shaped and conical elastic washer are used.
