Value Collection LWIS043USA-250BX Split Lock Washer 250

Product Description

The VALUE COLLECTION LWIS043USA-250BX is a steel split lock washer sized for 7/16 inch screws. It features an inside diameter of 0.44 to 0.45 inches and an outside diameter of 0.776 to 0.779 inches, with a thickness of 0.109 inches. The bright uncoated finish leaves the steel bare, which suits applications where a coating-free surface is required or where the installer will apply their own treatment. This washer ships in a box of 250 units. It is installed by electricians, plumbers, HVAC technicians, and general maintenance mechanics wherever a split lock washer of this screw size is specified.

Split lock washers in this size range are used in residential and light commercial mechanical assemblies to resist fastener loosening caused by vibration or thermal cycling. Typical applications include equipment panel mounting, conduit fittings, bracket hardware, and general structural fastening where a 7/16 inch fastener is used. The uncoated steel construction makes these suitable for indoor or protected environments where corrosion resistance is not the primary concern.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface before torquing. Ensure the split ends seat against both surfaces as the fastener is driven. These washers are intended for use in dry or protected indoor locations given the uncoated steel finish. Follow applicable codes and equipment manufacturer torque specifications when installing.
