Value Collection LWHIS043USA-100BX Split Lock Washer 100

Product Description

The VALUE COLLECTION LWHIS043USA-100BX is a Grade 2 spring steel split lock washer sized for 7/16 inch screws. The split ring design bites into the fastener and mating surface under torque load, resisting loosening from vibration and thermal cycling. With a minimum inside diameter of 0.44 inches, a maximum outside diameter of 0.784 inches, and a thickness of 0.133 inches, this washer fits standard 7/16 inch fastener assemblies. The uncoated bright finish is appropriate for indoor or dry applications. This box contains 100 washers. Licensed tradespeople and assemblers working on mechanical, HVAC, plumbing, or electrical enclosure applications will find this a straightforward OEM-style hardware consumable.

Split lock washers in this size range are used in residential and light commercial construction and equipment assembly wherever a 7/16 inch bolt or screw fastener requires vibration resistance. Typical applications include equipment mounting brackets, electrical panel hardware, HVAC unit assembly, and general structural fastening. This part is sold in a box quantity of 100, making it suitable for service vans, shop stock, or project-level quantities. The inch-standard dimensions fit standard SAE fastener patterns.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface, with the split gap oriented so both ends contact the mating surface as the fastener is tightened. Install with hand tools appropriate for the fastener drive type. Follow applicable mechanical or electrical codes when used in panel or equipment assemblies. Do not reuse lock washers that have been fully compressed flat, as spring tension will be reduced.
