UNI 1751 Spring lock washers– Metric stainless steel spring washers & shims

UNI 1751 spring lock washers is a disc lock spring washer, also called spring lock shims.  UNI1751 helical spring split lock washers are commonly used spring lock washers.  It is a split metal ring that is bent into a helical shape.  It causes the washer to exert a spring force between the fastener’s head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation.

Split Lock Washers are a left hand helix and allow the nut to be tightened in a right hand direction only. When compressed by tightening the nut, the washer bites into the substrate and exerts a spring force between the bolt and the substrate creating frictional resistance to rotation.
