Value Collection 88548656 Split Lock Washer 3/8 in Alloy Steel 50pk

Product Description

The VALUE COLLECTION 88548656 is an alloy steel split lock washer sized for 3/8-inch screws. Split lock washers are installed under a fastener nut or bolt head to resist loosening caused by vibration and torque relaxation. This washer features a bright, uncoated finish and is manufactured to inch-system dimensions. The inside diameter ranges from 0.382 to 0.393 inches, the maximum outside diameter measures 0.553 inches, and the thickness is 0.125 inches. Each package contains 50 washers. Tradespeople across HVAC, plumbing, electrical, and mechanical work use split lock washers daily wherever vibration-resistant fastening is required.

These washers are suited for general mechanical assembly, equipment mounting, and panel fastening in both residential and light commercial applications. They are appropriate wherever a standard 3/8-inch fastener is used and a friction-locking element is required between the fastener head or nut and the mating surface. The uncoated bright finish is compatible with most standard hardware and fastener finishes and is appropriate for dry or protected indoor installations.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before the fastener is driven to final torque. De-energize or shut off any system being serviced before accessing fastened components. Use appropriate hand tools and ensure the washer seats flat against the mating surface with the split ends fully compressed when the fastener is tightened.
