Value Collection FWUIB043-100BX Flat Washer Brass 7/16 in

Product Description

The VALUE COLLECTION FWUIB043-100BX is a standard flat washer sized for 7/16 inch screws, manufactured from brass with a plain finish. It features an inside diameter of 0.531 inches, an outside diameter of 1.25 inches, and a thickness of 0.081 inches. Flat washers of this type distribute fastener load across a wider surface area, protecting the workpiece and reducing the chance of fastener pull-through. The brass construction provides natural corrosion resistance without a plated or coated finish, making it suitable for applications where bare metal contact is preferred. Plumbers, electricians, HVAC technicians, and general trade contractors install these as part of standard mechanical assemblies.

This washer is used wherever a 7/16 inch fastener requires load distribution or surface protection. Common applications include pipe flange assemblies, electrical enclosure mounting, HVAC equipment panel fastening, and general mechanical construction. The plain brass finish suits installations where outgassing from coatings is undesirable or where galvanic compatibility with brass fittings and copper components is a priority. Sold in multiples of 5.

Key Features

• Standard flat washer geometry for 7/16 inch screw size
• Brass material provides inherent corrosion resistance without a coating
• Plain finish — no plating, no coating, no chemical treatment

Compatibility

Designed for use with 7/16 inch screws and bolts following inch-system measurement standards, suitable for standard mechanical, plumbing, electrical, and HVAC fastening assemblies requiring a brass flat washer.

Installation Notes

Installation requires no special tools beyond those used for the fastener itself. Place the washer flat against the workpiece surface before seating the fastener head or nut. Ensure mating fasteners are also brass or a compatible alloy to avoid galvanic corrosion in wet or humid environments. Follow applicable mechanical codes for torque and fastener selection based on the specific application.
