Value Collection FWI5100G-010BX Standard Flat Washer

Product Description

The VALUE COLLECTION FWI5100G-010BX is a standard flat washer designed for use with 1 inch screws and bolts. Manufactured from steel with material grades 1035 and 1050, this washer features a hot-dip galvanized finish for corrosion resistance in demanding environments. It measures 1.055 inches inside diameter, 2 inches outside diameter, and 0.177 inches thick. Conforming to ASTM F436 standards, it is suited for structural and mechanical fastening applications where a reliable, load-distributing washer is required. Plumbers, electricians, HVAC technicians, and general contractors commonly use these washers in equipment mounting, pipe support, and structural fastening tasks.

This flat washer is appropriate for residential and commercial construction and maintenance applications. It fits 1 inch fasteners and is used wherever a standard-series washer is called for under bolt heads or nuts to distribute clamping load and prevent surface damage. The galvanized coating makes it a practical choice for indoor and moderately corrosive outdoor environments, including mechanical rooms, utility installations, and structural assemblies.

Key Features

• Meets ASTM F436 fastener standard for structural flat washers
• Steel construction with 1035/1050 material grade for reliable strength
• Galvanized finish provides corrosion resistance in damp or outdoor-adjacent environments

Installation Notes

Flat washers are installed by placing the washer over the fastener shank before threading the nut or driving into the mating surface. Always ensure the inside diameter matches the fastener size to prevent washer migration under load. Follow applicable building or mechanical codes, such as the IBC or AISC guidelines, when using structural washers in load-bearing connections. Inspect the galvanized coating before installation and discard any washers with heavy surface corrosion or dimensional deformation.
