Value Collection 451028BR Hex Cap Screw 1-1/4-7 X 3 in Grade 8

Product Description

The VALUE COLLECTION 451028BR is a fully threaded hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets ASME B18.2.1 dimensional standards. The 1-1/4-7 UNC thread and 3-inch length under head make it suited for heavy-duty structural and mechanical assemblies where tensile strength and precise thread engagement are critical. Machinists, millwrights, and general contractors working on industrial equipment, structural steel connections, and heavy machinery will find this fastener a standard fit for demanding load-bearing joints.

This cap screw is used in industrial, commercial, and heavy equipment applications requiring a coarse unified thread pattern. Fully threaded along its 3-inch shank, it provides maximum thread engagement across the full bearing length. Typical installation scenarios include bolted flange connections, machinery bases, structural frames, and equipment mounting assemblies where Grade 8 strength is specified by the design engineer or maintenance standard.

Key Features

• Grade 8 steel construction for high tensile strength in heavy-duty fastening
• Fully threaded 3-inch shank for maximum thread engagement
• 1-1/4-7 UNC coarse thread meets standard tooling compatibility
• Bright uncoated finish suitable for use where secondary coating or plating will be applied
• Conforms to ASME B18.2.1 dimensional standard
• 1-11/16 inch hex key size for use with standard industrial wrenching tools

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 1-1/4-7 UNC threaded holes and nuts in industrial, structural, and heavy mechanical applications conforming to ASME B18.2.1.

Installation Notes

Installation is performed by qualified millwrights, maintenance mechanics, or structural ironworkers using calibrated torque wrenches and standard 1-11/16 inch hex tooling. Always clean and inspect threaded holes before installation and ensure mating threads are free of debris, damage, or misalignment. Follow the applicable engineering specification or torque table for Grade 8 fasteners at this diameter and thread pitch. De-energize or lock out equipment before fastener replacement on live machinery per applicable OSHA lockout/tagout procedures.
