Value Collection LWIS1501USA-010BX Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION LWIS1501USA-010BX is a Grade 8 spring steel split lock washer designed for 1-1/2 inch screw applications. The split lock design creates tension under a fastener head or nut, resisting loosening caused by vibration or dynamic loads. The washer features a yellow zinc dichromate finish that provides corrosion resistance in moderate service environments. With a minimum inside diameter of 1.504 inches, a maximum outside diameter of 2.419 inches, and a thickness of 0.375 inches, this washer meets standard dimensional requirements for heavy-duty bolted assemblies. It is commonly installed by millwrights, pipefitters, structural ironworkers, electricians, and mechanical contractors wherever reliable fastener retention is required.

This split lock washer is suited for use in structural, mechanical, and industrial assemblies that use 1-1/2 inch fasteners. Grade 8 spring steel construction makes it appropriate for high-load and high-vibration applications such as equipment mounting, machinery bases, pipe supports, and steel structural connections. The inch-measurement system designation confirms compatibility with standard SAE fastener hardware. This item is sold individually with a minimum order quantity of 10 pieces.

Installation Notes

Install this lock washer between the fastener head or nut and the mating surface before torquing to specification. Confirm the fastener grade is equal to or greater than Grade 8 to maintain assembly integrity. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective spring tension. Follow applicable codes and torque standards for the fastener size and joint classification in use.
