Value Collection 36731 Split Lock Washer 5/8 in 100 Pack

Product Description

The VALUE COLLECTION 36731 is a split lock washer sized for 5/8 inch screws, manufactured from AISI 4037 alloy steel with a zinc yellow dichromate finish. Split lock washers create tension under a fastener head or nut to resist loosening caused by vibration or dynamic loading. The 36731 carries an inside diameter range of 0.628 to 0.641 inches and a maximum outside diameter of 1.073 inches, with a thickness of 0.156 inches. This package contains 100 washers. Installers in mechanical, HVAC, plumbing, and electrical trades use this type of hardware wherever vibration-resistant fastening is required on standard 5/8 inch fasteners.

These split lock washers are suited to both residential and light commercial installation work. Typical applications include securing equipment mounts, panel hardware, pipe hangers, and structural fastener assemblies where fastener retention under vibration is a priority. The alloy steel construction and zinc yellow dichromate finish provide corrosion resistance appropriate for indoor and protected outdoor environments. This 100-piece package is practical for service vehicles, job-site kits, or stocking at a shop for recurring maintenance work.

Compatibility

Designed for use with standard 5/8 inch screws and bolts in inch-measurement fastener assemblies across mechanical, HVAC, plumbing, and electrical applications.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before final torque is applied. Ensure the washer is fully seated and the split ends are positioned to bite into the mating surface when the fastener is tightened. Follow applicable mechanical codes and equipment manufacturer torque requirements for the specific fastener assembly. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective locking tension.
