Value Collection 36727 Split Lock Washer 3/8 in 200 Pack

Product Description

The VALUE COLLECTION 36727 is a split lock washer sized for 3/8 inch screws, manufactured from AISI 4037 alloy steel with a zinc yellow dichromate finish. Split lock washers are installed under a fastener nut or bolt head to resist loosening caused by vibration and torque relaxation. The helical split creates spring tension as the fastener is tightened, biting into both the mating surface and the fastener bearing surface to maintain clamp load. This washer carries an inside diameter range of 0.377 to 0.385 inches, a maximum outside diameter of 0.68 inches, and a thickness of 0.094 inches. Licensed tradespeople and maintenance technicians in mechanical, electrical, plumbing, and HVAC work regularly use split lock washers in panel, equipment, and structural fastening assemblies.

This washer is suited for general industrial and trade applications where a standard 3/8 inch fastener is used and vibration resistance is required. Typical install scenarios include equipment mounting, conduit support brackets, mechanical enclosures, and structural connections in both residential and light commercial settings. The zinc yellow dichromate coating provides corrosion resistance appropriate for indoor and sheltered outdoor environments. This part is sold in a package quantity of 200, making it practical for service vans, job-site stock, and shop inventory replenishment.

Compatibility

Designed as a standard replacement or stocking split lock washer for use with 3/8 inch screw and bolt fasteners in inch-measurement fastening applications.

Installation Notes

Split lock washers are installed by placing tradespeople familiar with fastener hardware, including electricians, HVAC mechanics, and plumbers. Always de-energize electrical equipment and relieve system pressure before accessing fastened assemblies. Place the washer on the fastener shank before the nut, seating it flat against the bearing surface. Do not reuse washers that have been fully compressed flat, as the spring function will be lost.
