Stewart Fastener J3724WFZ 3/8x1-1/2 Zinc Fender Washer 100pk

Product Description

The STEWART FASTENER J3724WFZ is a zinc-plated fender washer with a 3/8-inch inner diameter and a 1-1/2-inch outer diameter, sold individually as part of a jar of 100 pieces. Fender washers feature a larger outer diameter relative to their hole size, which spreads load across a wider surface area and reduces pull-through on soft or thin materials. These are a standard hardware item used daily by HVAC technicians, plumbers, electricians, and general contractors for fastening applications where panel or surface protection is needed.

These zinc-plated fender washers are suited for both residential and light commercial construction and mechanical work. Common applications include equipment mounting, electrical panel installations, ductwork attachment, pipe strapping, and general structural fastening. The zinc coating provides corrosion resistance for indoor and moderate-exposure outdoor use. The jar-of-100 format makes them practical for service vehicles and shop stock, allowing techs to pull individual pieces as needed without handling bulk loose hardware.

Key Features

• 3/8-inch inner diameter fits standard 3/8-inch fasteners
• 1-1/2-inch outer diameter provides wide load-bearing surface to reduce pull-through
• Zinc plating offers corrosion resistance for indoor and moderate outdoor environments
• Sold per each washer from a jar of 100, allowing flexible quantity purchasing

Compatibility

Designed for use with 3/8-inch bolts, screws, and threaded rod in general mechanical, construction, and trade fastening applications.

Installation Notes

Install with the appropriate wrench or socket to match the fastener being used. Always ensure the washer seats flush against the mating surface before tightening. Do not exceed the rated load capacity of the fastener assembly. For outdoor or high-moisture applications, verify that zinc plating provides adequate corrosion resistance for the environment or consider a more protective coating.
