Ruisu Spring Washers Industrial Open gasket

Spring washer is generally used in the case that the pre-tightening force of the bolt is not high and the dynamic load is small. When the bolt clamping length is relatively short, the bolt stress relaxation will be more obvious, then the use of spring washers can make up for the stress relaxation.

The spring washer has good anti-loose effect and anti-seismic effect. The general direction of the thread is right-handed, and the spiral direction of the spring washer is left-handed. After tightening the nut, the elastic reaction generated by the washer flattening compels the screw threads. At the same time, when the fastener combination is subjected to the axial force of the vibration of the bolt, due to the elastic deformation of each part after the stress, sometimes there will be a gap between the fasteners, which is easier to loose. The tip of the spring washer’s oblique mouth is against the supporting surface of the bolt or nut and the connected part, which can make up for the gap between the instantaneous fasteners and prevent loosening.
