Value Collection 31804 Fender Flat Washer 5/16 in 18-8 Stainless

Product Description

The VALUE COLLECTION 31804 is a fender flat washer designed for use with 5/16 inch screws and fasteners. Manufactured from grade 18-8 stainless steel, it provides corrosion resistance suitable for both indoor and outdoor applications. The oversized outer diameter distributes clamping load across a wider surface area than standard flat washers, reducing pull-through on soft or thin materials. With an inside diameter of 11/32 inches and an outside diameter of 1-1/4 inches, this washer meets standard inch-system dimensional specs. Electricians, plumbers, HVAC technicians, and general trade professionals use fender washers when securing panels, brackets, conduit supports, and similar hardware where load spreading is required.

This fender washer is suited for residential and light commercial trade work where stainless steel hardware is specified for corrosion resistance. Common applications include securing electrical enclosures, plumbing brackets, HVAC equipment mounting, pool equipment installations, and structural panel fastening. The 18-8 stainless steel grade is widely accepted for general-purpose corrosion-resistant fastener applications in damp or outdoor environments. Sold individually with a minimum order quantity of 50 pieces.

Installation Notes

Install using standard hand tools appropriate to the fastener type. Ensure the washer seats flat against the mating surface before tightening to achieve proper load distribution. When used in electrical enclosure or conduit applications, follow NEC guidelines for hardware and grounding requirements. No special torque procedure is required beyond what the fastener manufacturer or applicable code specifies for the screw size.
