Professional Applications & Engineering Value

This spring lock washer delivers critical vibration resistance in heavy machinery, automotive assemblies, and industrial equipment where reliable locking action is paramount. The conical shape creates constant spring tension that compensates for joint settlement and thermal cycling, preventing catastrophic fastener failure. Engineered with external teeth that aggressively grip both the bearing surface and fastener head, this steel washer maintains clamp load integrity in high-vibration environments. The precise 1.792" ID and 2.734" OD dimensions ensure perfect compatibility with 1.767"-18 screw sizes and chamfered bearing nuts, eliminating installation issues and reducing assembly time. Ideal for maintenance, repair, and OEM applications requiring ANSI/ABMA 8.2 certified components that meet rigorous industrial standards.
