Value Collection 37WFAL Standard Flat Washer 3/8 in Aluminum

Product Description

The Value Collection 37WFAL is a standard flat washer designed for use with 3/8-inch screws and fasteners. Constructed from aluminum, this washer distributes load across a fastened joint, reducing surface damage and preventing pull-through on softer substrates. The washer measures 0.436 inches inside diameter, 1 inch outside diameter, and 0.081 inches thick. It conforms to standard inch-system dimensioning and is suited for general mechanical assembly, structural fastening, and maintenance applications across a wide range of industries.

This flat washer is appropriate for use in residential, commercial, and industrial settings where a lightweight, corrosion-resistant fastening component is required. Common applications include HVAC equipment assembly, plumbing fixture mounting, electrical enclosure work, and general mechanical construction. The aluminum material makes it a practical choice in environments where steel washers may corrode or where weight savings are a factor in the assembly design. Sold in multiples of 100 per minimum order.

Installation Notes

Install using standard hand tools appropriate for the fastener type. Ensure the fastener shank passes cleanly through the inside diameter without binding before torquing. Aluminum washers are softer than steel and should not be used in applications with extreme clamping loads that could deform the washer face. Always follow applicable mechanical codes and manufacturer fastener specifications for the assembly being serviced.
