Dottie LW58 Washer, 5/8" Lock Washer

Keep critical mounts and connections secure in demanding installations with the Dottie LW58 Lock Washer. Designed to resist vibration-induced loosening, this 5/8" split lock washer maintains clamp force on rotating or friction-prone fasteners—making it a reliable choice for security, surveillance and monitoring equipment, camera mounts, conduit fittings and server rack hardware. Forged from hardened spring steel and zinc-coated, the LW58 delivers durable corrosion resistance and long-term performance in both indoor and protected outdoor environments. Supplied in a convenient 100-pack and manufactured to ASME B18.21.1 standards, these lock washers provide consistent dimensions and predictable behavior that help reduce rework and simplify inventory management for contractors and integrators. Use the Dottie LW58 with or without a hardened flat washer to stabilize torque and minimize maintenance on low-voltage, IT and physical security systems.
