Value Collection LWHIS037USA-100BX Split Lock Washer

Product Description

The VALUE COLLECTION LWHIS037USA-100BX is a Grade 2 spring steel split lock washer designed for use with 3/8 inch screws and fasteners. The split lock design applies tension against the fastener head and mating surface to resist loosening caused by vibration and torque. With an inside diameter of 0.377 inches and a maximum outside diameter of 0.688 inches, this washer fits standard 3/8 inch fastener assemblies. The bright uncoated finish is typical for indoor and dry-environment mechanical assemblies. This box quantity of 100 pieces is suited for production work, maintenance shops, and job-site stocking.

Split lock washers of this type are used across general mechanical, electrical, HVAC, plumbing, and light structural applications wherever threaded fastener retention is needed. They are installed between the fastener head and the bearing surface during assembly. Common install scenarios include equipment panels, brackets, junction boxes, and mechanical frames in both residential and light commercial settings. The 100-piece minimum order quantity makes this item practical for contractors and maintenance technicians who go through hardware in volume.

Installation Notes

Split lock washers are installed by placing the washer on the fastener shank before threading into the mating surface, with the split gap oriented so both ends bear against the fastener head and mating material when torqued. Ensure the mating surface and fastener threads are clean and free of debris before assembly. For electrical enclosures or panel work, follow applicable NEC guidelines for fastener torque and hardware selection. Do not reuse compressed split lock washers, as a fully flattened washer no longer provides locking force.
