Value Collection FWI5125-005BX Structural Flat Washer

Product Description

The VALUE COLLECTION FWI5125-005BX is a structural flat washer designed for use with 1-1/4-inch screws and bolts in load-bearing fastener assemblies. Manufactured from steel with material grades 1035 and 1050, this washer meets ASTM F436 specifications, making it appropriate for structural steel connections where consistent bearing surface and load distribution are required. The plain finish provides bare steel protection suitable for dry or controlled environments. At 0.1 pounds per unit, it is a lightweight but code-compliant component for professional fastener applications.

This washer is used in structural steel construction, heavy equipment assembly, and industrial fastening applications where ASTM F436-compliant hardware is specified. Typical install scenarios include bolted steel connections in framing, equipment mounting, and bridge or building structural joints. It is installed by ironworkers, construction crews, and mechanical contractors working to structural fastener specifications. The inch-measurement system sizing makes it compatible with standard imperial fastener hardware used across North American construction projects.

Key Features

• Meets ASTM F436 structural washer standard for load-bearing fastener assemblies
• Steel construction with 1035 and 1050 material grade for high-strength performance
• 1-3/8-inch inner diameter fits 1-1/4-inch nominal screw and bolt sizes
• 2-1/2-inch outer diameter provides a wide bearing surface for load distribution
• Plain finish for uncoated bare steel applications
• Inch-system dimensioning for direct compatibility with imperial fastener hardware

Compatibility

Designed as an OEM-style replacement and standard fitment structural flat washer for use with 1-1/4-inch nominal fasteners in ASTM F436-specified structural steel assemblies.

Installation Notes

Structural flat washers of this type are installed by licensed contractors and ironworkers as part of bolted structural connections governed by applicable building codes and structural engineering specifications. Power down or de-energize any adjacent electrical systems before working in close proximity to live panels or conduit runs. Do not substitute this washer in applications requiring a galvanized, hardened, or coated finish where the project specification calls for corrosion protection. Torque values and installation procedures should follow the project engineer of record or the applicable structural specification.
