Stewart Fastener J3732WFZ Fender Washer 3/8x2 in Jar 100

Product Description

The STEWART FASTENER J3732WFZ is a 3/8 x 2 inch fender washer sold in a jar of 100 pieces per unit. Fender washers feature a larger outer diameter relative to the center hole, distributing load over a wider surface area and reducing pull-through on thin materials, soft substrates, or oversized holes. This listing is sold per each jar of 100. These washers are a standard fastener component used across HVAC installation, plumbing rough-in, electrical panel work, pool equipment mounting, and general construction trade applications where a wide-bearing washer is required.

Fender washers in this size range are commonly used in light-gauge sheet metal assembly, equipment mounting, and strap or bracket fastening. Trades including HVAC installers, plumbers, electricians, and pool equipment technicians reach for fender washers when standard flat washers lack sufficient bearing surface. The 3/8 inch inner diameter fits standard 3/8 inch bolt or threaded rod, making this a versatile fastener for multi-trade use on residential and light commercial jobsites.

Key Features

• 3/8 inch inner diameter fits standard 3/8 inch fasteners
• 2 inch outer diameter provides wide load-bearing surface to reduce pull-through
• Sold as one jar containing 100 washers for jobsite or shop stocking
• Suitable for multi-trade use across HVAC, plumbing, electrical, and pool equipment applications

Compatibility

Fender washers are installed by any trade technician as part of standard fastener assembly. Ensure the mating fastener diameter matches the 3/8 inch center hole before installation.
