Value Collection KP72511 Fender Flat Washer 7/16 in 100pk

Product Description

The VALUE COLLECTION KP72511 is a zinc-plated steel fender flat washer sized for 7/16-inch screws. Fender washers feature a larger-than-standard outside diameter, which spreads clamping load over a wider surface area and reduces the risk of pull-through in softer or thinner substrates. This washer has an inside diameter of 0.4531 inches, an outside diameter of 1.5 inches, and a thickness of 0.0625 inches. The zinc plating provides a baseline level of corrosion resistance suited to general indoor and light-duty applications. Sold in a 100-piece package, this lot is appropriate for service vans, maintenance shops, and job-site replenishment.

Fender washers of this screw size are commonly used by HVAC technicians, plumbers, electricians, and general maintenance trades when fastening sheet metal, panels, junction box covers, mounting brackets, and similar assemblies. The enlarged OD makes them especially useful when the clearance hole in the mating material is oversized or when load distribution over a broad face is required. These washers are used in residential and light commercial applications where inch-measurement hardware is standard.

Compatibility

Designed for use with 7/16-inch screws and bolts in standard inch-measurement fastener assemblies across HVAC, plumbing, electrical, and general mechanical applications.

Installation Notes

Install using hand tools appropriate for the mating fastener type and size. Ensure the fastener and washer material are compatible with the substrate to avoid galvanic corrosion in wet or outdoor environments. Zinc-plated finishes are not recommended for prolonged exposure to standing water, salt spray, or highly corrosive atmospheres without additional protective measures. Always follow applicable trade codes and manufacturer guidelines for fastener torque and assembly specifications.
