Value Collection BDNA-32580 Fender Flat Washer 3/8 in

Product Description

The VALUE COLLECTION BDNA-32580 is a zinc-plated steel fender flat washer sized for 3/8 inch screws. Fender washers feature a larger outside diameter relative to the inside diameter, spreading clamp load over a wider surface area to reduce pull-through and damage to soft or thin materials. This washer has a 7/16 inch inside diameter, a 1-1/2 inch outside diameter, and a thickness of 0.0625 inches. The zinc plating provides basic corrosion resistance suitable for general indoor and light outdoor fastening applications. HVAC techs, plumbers, electricians, and general contractors reach for fender washers when securing sheet metal panels, mounting brackets, or routing straps where a standard washer footprint is too small.

This washer is used across residential and light commercial construction and service work. Common applications include securing electrical junction box covers, mounting HVAC components to sheet metal framing, fastening conduit straps, attaching pipe hangers, and general structural panel assembly. The larger bearing surface makes it especially useful wherever the base material is soft, thin, or prone to fastener pull-through. Sold individually with a minimum order quantity of 100 pieces, making it practical for stocking in service vans or shop bins.

Key Features

• Larger 1-1/2 inch outside diameter spreads load and reduces material pull-through
• 7/16 inch inside diameter fits standard 3/8 inch fasteners with close clearance
• 0.0625 inch thickness provides consistent bearing surface without adding excessive stack height
• Zinc-plated steel construction offers corrosion resistance for general-purpose use
• Inch measurement system for straightforward compatibility with standard SAE hardware

Compatibility

Designed for use with 3/8 inch screws and bolts in standard SAE fastener applications across HVAC, plumbing, electrical, and general construction trades.

Installation Notes

Install with hand tools; no special equipment is required. Place the washer on the fastener before driving to ensure proper seating against the work surface. Do not exceed the torque capacity of the base fastener or the structural rating of the mating material. For outdoor or high-moisture environments, consider a higher-grade corrosion-resistant finish if long-term exposure is expected.
