Stewart Fastener J2520WFZ Fender Washer Zinc 100 Pack

Product Description

The STEWART FASTENER J2520WFZ is a zinc-plated fender washer with a 0.25-inch inner diameter and a 1.25-inch outer diameter. Fender washers distribute load across a wider surface area than standard flat washers, reducing pull-through on softer materials and protecting finished surfaces from fastener damage. The zinc plating provides basic corrosion resistance suitable for interior and light exterior applications. These washers are sold individually per jar, with each jar containing 100 pieces, making them practical for job-site stocking and small-quantity restocking.

Fender washers in this size are commonly used in residential and light commercial construction, HVAC equipment mounting, plumbing fixture installation, electrical enclosure work, and general sheet metal assembly. The larger outer diameter is particularly useful when fastening into oversize holes, slotted openings, or thin-gauge sheet materials where a standard washer would not provide adequate bearing surface.

Key Features

• 0.25-inch inner diameter fits standard quarter-inch fasteners
• 1.25-inch outer diameter provides broad load distribution
• Zinc plating for corrosion resistance in dry and light-moisture environments
• 100 pieces per jar for convenient job-site storage and inventory control
• Compatible with a wide range of bolt, screw, and stud fastener types

Compatibility

Designed as a standard fender washer for use with 0.25-inch fasteners across general trade, construction, and mechanical assembly applications.

Installation Notes

Installation requires no special tools beyond standard hand or power fastening equipment. Ensure the mating fastener and nut or thread engagement meet the load requirements of the application. Zinc-plated hardware is not recommended for direct contact with pressure-treated lumber or highly corrosive environments without additional protective measures. Follow applicable building and mechanical codes for fastener selection and installation torque.
