Value Collection LWIS056USA-200BX Split Lock Washer 200

Product Description

The VALUE COLLECTION LWIS056USA-200BX is a 9/16 inch steel split lock washer sold in a box of 200. Split lock washers are hardened fastener components used to resist loosening caused by vibration and torque relaxation in bolted assemblies. This washer fits a 9/16 inch screw and features a bright, uncoated finish on a standard steel construction. The inside diameter ranges from 0.564 to 0.574 inches and the outside diameter ranges from 0.965 to 0.971 inches, with a thickness of 0.141 inches. These washers are installed by electricians, plumbers, HVAC technicians, pipefitters, and general mechanical trades wherever vibration resistance is required in a fastened joint.

This split lock washer is suited for use in residential and commercial mechanical assemblies, equipment mounting, panel work, pipe supports, duct hangers, and structural fastening applications. The 9/16 inch screw size makes it compatible with standard fractional-inch fastener systems commonly found in mechanical, electrical, and plumbing installations. The bright uncoated finish is appropriate for interior or protected environments. The 200-piece box quantity supports job-site and shop restocking needs for high-use fastener programs.

Compatibility

Designed for use with 9/16 inch fractional-inch screws and bolts in standard inch-measurement fastener assemblies across mechanical, electrical, plumbing, and HVAC applications.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before final torque is applied. Power down or de-energize any equipment before servicing fastened assemblies on electrical or mechanical systems. Use appropriate hand tools and follow applicable codes such as NEC or IFGC where fastener torque requirements are specified by equipment manufacturers. Do not reuse split lock washers that have been fully compressed or deformed, as spring tension will be reduced.
