Value Collection FNWIS03701620-100BX Fender Flat Washer

Product Description

The VALUE COLLECTION FNWIS03701620-100BX is a zinc-plated steel fender flat washer sized for 3/8 inch screws. Fender washers feature a larger outside diameter relative to their inside diameter, spreading clamp load across a wider surface area to prevent pull-through and reduce surface damage. This washer has a 13/32 inch inside diameter, a 1-5/8 inch outside diameter, and a thickness of 0.08 inches. The zinc plating provides basic corrosion resistance in general-purpose indoor and light outdoor applications. Plumbers, electricians, HVAC technicians, and general maintenance trades keep these on hand for panel mounting, pipe hangers, conduit support, and sheet metal work.

This washer suits a wide range of trade and maintenance applications where a standard flat washer footprint is too small to hold securely. Common uses include securing sheet metal panels, mounting junction boxes, fastening conduit straps, and supporting pipe hanger assemblies. The 3/8 inch screw size is one of the most common fastener diameters in commercial and residential mechanical, electrical, and plumbing work, making this washer a high-frequency shop consumable. Sold in minimum quantities of 100 per order.

Key Features

• Large OD-to-ID ratio distributes load and reduces pull-through on soft or thin materials
• Zinc-plated finish offers corrosion resistance for general indoor and light-duty outdoor use
• Steel construction provides reliable shear and tensile strength for standard fastening tasks
• 3/8 inch screw size fits one of the most common fastener diameters in trade work
• 0.08 inch thickness keeps the stack height low in tight assembly clearances

Compatibility

Designed for use with 3/8 inch screws and bolts in standard inch-measurement fastener assemblies across HVAC, plumbing, electrical, and general mechanical applications.

Installation Notes

Install using standard hand tools; no special tooling is required. Ensure the mating fastener and surface material are compatible with zinc-plated steel before installation in wet or chemically active environments. Follow applicable codes such as NEC or IPC when using fasteners in electrical or plumbing system supports. Do not exceed the rated load capacity of the fastener assembly.
