Value Collection LWHIS0310USA-100BX Split Lock Washer 100

Product Description

The VALUE COLLECTION LWHIS0310USA-100BX is a Grade 2 spring steel split lock washer designed for use with 5/16 inch screws and fasteners. The split lock design applies tension under the fastener head or nut, resisting loosening caused by vibration and torque. With an inside diameter of 0.314 inches and a maximum outside diameter of 0.593 inches, this washer fits standard 5/16 inch hardware. A zinc plated finish provides basic corrosion resistance in general service environments. This box contains 100 individual washers, making it a practical restocking unit for shops, contractors, and maintenance teams.

Split lock washers of this type are widely used in mechanical assemblies, structural connections, and equipment maintenance across plumbing, HVAC, electrical, and general construction trades. They are appropriate for indoor and light outdoor applications where a standard Grade 2 fastener is specified. The zinc plated finish suits dry to mildly humid environments. These washers are installed by hand prior to driving the fastener and are compatible with standard hex bolts, machine screws, and hex cap screws in the 5/16 inch size class.

Installation Notes

Split lock washers are installed by placing them between the fastener head or nut and the mating surface before tightening. Power down or de-energize any equipment before performing fastener service on mechanical or electrical assemblies. Use appropriate hand tools or power drivers set to a controlled torque to avoid over-compression of the washer. Do not reuse visibly deformed or cracked lock washers.
