Dottie LWS12 Washer, 1/2" Stainless-Steel Lock Washer

Keep critical mounts and assemblies secure with the Dottie LWS12 Washer, a 1/2 in stainless-steel lock washer engineered for commercial and security applications. Forged from 18-8 stainless steel and manufactured to ASME B18.21.1 dimensions, this split lock washer uses a trapezoidal cross section to deflect under load and maintain tension — reducing the risk of fastener rotation and vibration-induced loosening. At 0.5 in diameter and available in a convenient 100-count package, the LWS12 streamlines procurement and on-site inventory for technicians installing CCTV, access control, networking racks, and other surveillance or monitoring equipment. Its compatibility with or without a flat washer gives installers flexibility across metal, wood and composite mounting surfaces. For integrators and maintenance teams focused on uptime, corrosion resistance and consistent performance, the Dottie LWS12 provides a simple, cost-effective way to secure critical infrastructure.
