    ANSI ASME B181.21.1 3 Inch Helical Spring Steel Washers

    Split lock washers provide greater bolt tensioning for tighter assemblies and provide protection against loosening resulting from vibration. Lock washers can be used with a standard washer to provide uniform bearing surface. These washers are intended for general use.

    Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener. Lock washers are made from such hardened metals as stainless steel, galvanized steel, zinc-plated steel and silicone bronze.
