Value Collection FWUIB100-025BX Flat Washer Brass 1 in

Product Description

The VALUE COLLECTION FWUIB100-025BX is a standard flat washer machined from brass with a plain, uncoated finish. It is sized for 1-inch screws and provides a broad bearing surface that distributes clamping load, prevents fastener pull-through, and protects mating surfaces during assembly. The washer measures 1.062 inches inside diameter, 2.5 inches outside diameter, and 0.144 inches thick. Brass construction resists corrosion and is well suited for applications where galvanic compatibility with copper or bronze fasteners is required. Plumbers, electricians, HVAC technicians, and general mechanical contractors regularly use this style of washer in both new construction and maintenance work.

This flat washer is used in plumbing assemblies, electrical enclosures, HVAC equipment mounting, and general mechanical fastening where a 1-inch screw or bolt is the fastener of record. It is appropriate for indoor and light outdoor applications. The plain finish keeps the brass surface natural, which is acceptable in most corrosion-resistant and non-ferrous fastening scenarios.

Key Features

• Brass material provides natural corrosion resistance and galvanic compatibility with copper and bronze fasteners
• 1.062-inch inside diameter fits 1-inch nominal screw size with standard clearance
• 2.5-inch outside diameter delivers a wide bearing surface to distribute clamping load
• 0.144-inch thickness meets standard flat washer dimensional requirements
• Plain finish with no coating keeps the surface natural for soldering or conductive applications
• Inch measurement system; conforms to UNSPSC code 31161807

Compatibility

Designed as a standard flat washer for use with 1-inch nominal screw or bolt fasteners in plumbing, HVAC, electrical, and general mechanical assembly applications.

Installation Notes

Installation is performed by hand or with standard wrenches and does not require special tooling. Place the washer on the fastener between the nut or bolt head and the mating surface before torquing. Brass is a softer metal than steel; avoid over-torquing, which can deform the washer and reduce clamping effectiveness. Follow applicable codes such as NEC or IPC for fastener requirements in regulated installations.
