Professional Applications & Engineering Value
This spring lock washer delivers critical vibration resistance in heavy machinery, automotive assemblies, and industrial equipment where dynamic loads threaten fastener integrity. The conical shape provides continuous spring action that compensates for thermal expansion, material relaxation, and vibration-induced loosening. External teeth create positive mechanical locking by embedding into both the bearing surface and fastener head, eliminating the need for additional locking mechanisms. Engineered specifically for 1.967"-18 screw applications, this steel washer maintains clamp force in high-vibration environments while the chamfered bearing nut face style ensures proper seating and load distribution. The combination of precise dimensions and ANSI/ABMA 8.2 compliance guarantees reliable performance in critical assembly operations.
