Lock Washers
Lock washers are hardened metallic components — typically manufactured from corrosion-resistant steel, titanium, or A286 stainless alloy to AMS and NAS material specifications — designed to resist fastener back-off under vibration and dynamic loading, encompassing split (helical spring), internal-tooth, external-tooth, and serrated-flange types produced via stamping, heat treatment, and surface finishing processes such as cadmium or dry-film lubrication.
