The VALUE COLLECTION LWIS125USA-025BX is a steel split lock washer sized for 1-1/4 inch screws. It features an inside diameter of 1.254 to 1.28 inches and an outside diameter of 2.036 to 2.045 inches, with a thickness of 0.312 inches. The bright, uncoated finish leaves the steel surface bare, making it suitable for applications where a coating is not required or where the installer will apply their own treatment. This washer is sold in a minimum order quantity of 25 pieces. Machinists, millwrights, pipefitters, and general maintenance trades use split lock washers to resist fastener loosening caused by vibration or dynamic loads.
This split lock washer is appropriate for use in mechanical assemblies, structural connections, piping supports, and equipment mounting where a 1-1/4 inch fastener is specified. The helical split design creates a spring-like tension against the mating surfaces when the fastener is tightened, helping to maintain clamp load under vibration. It is used across residential, commercial, and industrial applications wherever standard inch-series fastener hardware is called for.
Designed for use with standard inch-series 1-1/4 inch screws and bolts in mechanical, structural, and equipment-mounting applications.
Install split lock washers between the fastener head or nut and the mating surface before torquing the fastener. Ensure the mating surface is clean and free of debris so the washer seats flat. Follow the applicable torque specification for the fastener grade and size per the relevant ASME or project standard. Do not reuse a split lock washer that has been fully compressed flat, as it will no longer provide effective spring tension.
