Spring washers are essential fasteners used in Automotive Industry, White Goods Industry, Furniture Industry, and any other sectors where bolts and nuts are used. A spring washer ensures equal distribution of load, and prevents loss of friction grips between bolt and thread, i.e. loosening.
A spring washer is placed between nut and object, stopping the nut. When the ring nut is tightened, the potential force placed on the underlying washer applies a force to the nut contrary to that of the tightening direction, thus increasing the friction coefficient. As a result, the nut will be neither tightened nor loosened easily. Furthermore, it ensures a homogenous distribution of pressure on the surface tightened by the nut.
Spring washers are placed under a screw, bolt, or nut, and distribute the pressure during tightening and loosening of screw to protect the work piece. Washers are also used for ensuring humidity-proof connection.
