Dottie LWS516 Washer, 5/16" Stainless-Steel Lock Washer

Secure critical equipment quickly and confidently with the Dottie 5/16 in Stainless-Steel Lock Washer (LWS516). Designed to resist vibration and maintain clamp load, this split lock washer helps prevent fasteners from backing out in demanding security, surveillance and monitoring environments. Forged from 18-8 stainless steel and compliant with ASME B18.21.1, the washer delivers corrosion resistance and consistent performance for both indoor and outdoor installations. The trapezoidal cross section deflects under load to bite into the assembly and reduce rotation, making it ideal for camera mounts, access control plates, network racks and other low-voltage or networking hardware. With a 0.31 in diameter (5/16 in) fit and compatibility with or without a flat washer, the LWS516 provides installers the flexibility they need on-site. Supplied in packs of 100, these lock washers are a practical choice for contractors, integrators and facilities teams looking to minimize downtime and callbacks.
