Split Lock Washers, High Alloy, Plain

A Split Washer, a Locking Washer or a Spring Lock Washer is a ring split at one point and bent into a helical shape. This 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. Applicable standards are ASME B18.21.1, DIN 127B, and United States Military Standard NASM 35338 (formerly MS 35338 and AN-935).


Specification Requirements:

● Dimensions:ASME B18.21.1.

● Material:Alloy Steel, SAE J404 4037.

● Finish:Light protective oil.
