Value Collection LWHIS056USA-050BX Split Lock Washer 50pk

Product Description

The VALUE COLLECTION LWHIS056USA-050BX is a Grade 2 spring steel split lock washer designed for use with 9/16 inch fasteners. The split ring design bites into the bearing surface under load, resisting loosening caused by vibration and torque. With a minimum inside diameter of 0.564 inches, a maximum outside diameter of 0.975 inches, and a thickness of 0.17 inches, this washer meets standard dimensional requirements for 9/16 inch screw applications. The uncoated bright finish suits general-purpose indoor and controlled-environment installations. Licensed tradespeople and maintenance technicians commonly specify this washer in structural, mechanical, and equipment-mounting applications.

This split lock washer is suited for a wide range of mechanical and structural fastening tasks in residential, commercial, and light industrial settings. It is commonly used in HVAC equipment mounting, electrical panel and conduit support assemblies, plumbing fixture attachment, and general mechanical equipment installation where fastener retention under vibration is required. The package contains one box with a minimum order quantity of 50 washers, making it appropriate for service vans, shop stock, and jobsite replenishment.

Compatibility

Installation Notes

Split lock washers are installed between the fastener head or nut and the bearing surface before final torque is applied. Always power down or de-energize equipment before accessing fastened assemblies in electrical or HVAC systems. Use the appropriate drive tool to achieve consistent clamping load without over-torquing, which can flatten the split and reduce locking effectiveness. Follow applicable codes such as NEC or IFGC when installing fasteners in regulated systems.
