    Product Description

     

    Flat washers are usually thin pieces of various shapes to reduce friction, prevent leaks, isolate, prevent loosening, or distribute pressure. This material is used in many materials and structures to perform a variety of similar functions. Due to the limitations of the material and process of the threaded fasteners, the bearing surfaces of the fasteners such as the bolts are not large, so that the surface of the parts to be joined is protected to reduce the compressive stress of the bearing surface, and washers are used.

    Flat Metal Washers, which is mainly punched out with an iron plate, is generally a flat washer with a hole in the middle. There is a calculation formula in the “Compound Encyclopedia of Standard Fasteners” published by China Standards Publishing House. The formula is: Thousand pieces weight m=0.00785×{3.1416/4×washer height×(single circle diameter-square of inner hole diameter) }

     

    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.
