Value Collection MP36745-3/8 High Collar Split Lock Washer

Product Description

The VALUE COLLECTION MP36745-3/8 is a high collar split lock washer designed for use with 3/8 inch screws. Made from uncoated steel, this washer provides mechanical resistance to loosening caused by vibration and torque load. The high collar profile adds extra grip and bite against the fastened surface, making it suitable for applications where standard flat or regular split lock washers may not provide adequate retention. Each package contains 50 washers. Licensed tradespeople and maintenance professionals working with threaded fastener assemblies will find this a reliable hardware staple.

This split lock washer is used in general mechanical, industrial, and trade assembly applications where 3/8 inch fasteners are specified. It is suited for structural connections, equipment mounting, panel attachment, and mechanical assemblies in HVAC, plumbing, electrical, and general industrial service environments. The uncoated steel finish is appropriate for interior or protected installations where corrosion exposure is minimal. Sold in a package of 50 units, this washer is practical for both single-job use and small-quantity stocking.

Installation Notes

Install between the fastener head or nut and the mating surface, with the split gap oriented to bite into both surfaces as the fastener is tightened. Power down or de-energize any equipment before accessing fastener assemblies in live systems. Use appropriate hand tools and follow applicable mechanical codes for the specific trade application. Do not reuse split lock washers that have been fully compressed or deformed, as they will not provide reliable locking force.
