Value Collection FENW0310150OZ Fender Flat Washer 5/16 in

Product Description

The VALUE COLLECTION FENW0310150OZ is a zinc-plated steel fender flat washer designed to distribute load over a larger surface area than a standard washer. With a 5/16-inch inside diameter and a 1.5-inch outside diameter, this fender washer provides a wide bearing surface suited for applications where fastener pull-through or surface damage must be minimized. The zinc plating provides basic corrosion resistance for general indoor and light outdoor use. At 0.049 inches thick, the washer maintains a low profile while delivering reliable clamping support under bolt or screw heads.

This fender washer is commonly used in HVAC panel assembly, electrical enclosure mounting, plumbing fixture installation, and light structural fastening tasks. It is well suited for trade professionals who need a high-ratio OD-to-ID washer to spread clamp load across sheet metal, thin substrates, or soft materials. The 5/16-inch screw size makes it compatible with the most commonly used bolts and machine screws across mechanical and installation trades.

Installation Notes

Fender washers are installed by mechanical, HVAC, plumbing, and electrical tradespeople as part of standard fastening assemblies. Always ensure the washer ID matches the fastener shank diameter before assembly. Do not exceed the rated clamp load for the mating fastener grade. Follow applicable mechanical codes and manufacturer fastener specifications for the assembly being serviced.
