Product Description

The VALUE COLLECTION MP36745-7/16 is a high collar split lock washer designed for use with 7/16 inch screws and fasteners in mechanical, electrical, and plumbing assembly applications. Constructed from uncoated steel, this washer provides reliable tension and vibration resistance at the fastener interface. The high collar profile increases the contact surface area compared to standard split lock washers, helping to maintain clamp load under dynamic loads. Key dimensional specs include an inside diameter range of 0.443 to 0.455 inches, a maximum outside diameter of 0.647 inches, and a thickness of 0.14 inches. Sold in a package of 25 pieces per order.

This washer is suited for general trade and industrial assembly work where 7/16 inch fasteners are used. Common applications include HVAC equipment mounting, electrical panel and conduit hardware, plumbing bracket assemblies, and structural component fastening. The uncoated steel finish is appropriate for interior or protected installations. Tradespeople in mechanical, electrical, and plumbing disciplines will encounter this washer as a standard hardware component in equipment installation and service work.

Installation Notes

Install between the fastener head or nut and the mating surface with the split gap oriented away from the bearing surface before torquing.

Follow applicable codes and equipment manufacturer torque specifications for the assembly being serviced. Do not reuse lock washers that have been fully compressed flat, as the spring tension will have been lost.
