Value Collection FENW0310125OZ Fender Flat Washer 5/16 in

Product Description

The VALUE COLLECTION FENW0310125OZ is a zinc-plated steel fender flat washer designed for 5/16 inch screw applications. With an inside diameter of 0.3125 inches, an outside diameter of 1.25 inches, and a thickness of 0.049 inches, this washer distributes load across a wider surface area than standard flat washers. The larger OD relative to the screw size makes fender washers well suited for soft substrates, oversized holes, or applications where pull-through resistance is critical. Electricians, plumbers, HVAC techs, and general tradespeople reach for this style of washer in both structural and equipment-mounting scenarios where a conventional washer footprint is insufficient.

This washer is used in residential and light commercial applications where a 5/16 inch fastener is paired with material that requires broader clamping surface coverage. Common install scenarios include panel mounting, equipment bracketing, sheet metal work, and conduit or pipe strap fastening. The zinc finish provides corrosion resistance suitable for dry to mildly humid indoor environments. Sold individually per package with a minimum order quantity of 100 pieces, making this item appropriate for shop stock, service vans, or project bulk purchasing.

Key Features

• Large 1.25 inch OD provides wide load distribution for 5/16 inch screw applications
• Steel construction offers reliable tensile and shear strength for mechanical fastening
• Zinc plating adds corrosion resistance for indoor and protected-environment use
• 0.049 inch thickness maintains a low profile while supporting clamping integrity
• Inch measurement system for direct compatibility with standard US fastener hardware

Compatibility

Designed for use with 5/16 inch screws and bolts in standard inch-measurement fastening applications across HVAC, electrical, plumbing, and general mechanical assembly work.

Installation Notes

Install using hand tools appropriate to the fastener type paired with this washer. Ensure the washer seats flat against the work surface before torquing the fastener to avoid uneven load distribution. For outdoor or high-moisture environments, evaluate whether additional corrosion protection beyond the zinc finish is required. No special trade license is required for fastener installation, though always follow applicable building and equipment codes for the assembly being serviced.
