Value Collection LWIS031USA-500BX Split Lock Washer 500BX

Product Description

The VALUE COLLECTION LWIS031USA-500BX is a steel split lock washer sized for 5/16 inch screws and fasteners. Split lock washers apply spring tension under a fastener head or nut to resist loosening caused by vibration and torque relaxation. This washer features an uncoated, bright finish and an inside diameter ranging from 0.314 to 0.322 inches with an outside diameter of 0.583 to 0.586 inches and a thickness of 0.078 inches. Sold in a 500-count box, this SKU suits high-volume fastener work across HVAC, electrical, plumbing, and general mechanical assembly where consistent hardware supply is needed.

Split lock washers of this size are widely used in residential and light commercial mechanical installations. They are appropriate wherever a 5/16 inch threaded fastener must resist vibration-induced loosening, including equipment mounting, panel assembly, and structural bracketing. The 500-piece minimum order quantity makes this suited to contractors and shop-stocking operations that consume hardware at volume rather than individual service calls.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before final torquing. Place the washer flat side down against the work surface and the split end facing the fastener bearing surface. Always de-energize or shut off any system before disassembling fastened components in live electrical or mechanical assemblies. Use appropriate drive tools to avoid deforming the washer during tightening.
