Value Collection 440654BR Hex Cap Screw 7/8-9 X 2-1/2 in Grade L9

Product Description

The VALUE COLLECTION 440654BR is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade L9 steel with a zinc yellow dichromate finish, this fastener delivers a tensile strength of 180,000 psi and corrosion resistance suited for demanding service environments. The 7/8-9 UNC thread pattern and 2.5-inch length under head make it a standard fit for heavy-duty bolted connections. Licensed trades including millwrights, ironworkers, pipefitters, and maintenance mechanics regularly specify Grade L9 fasteners where high preload and fatigue resistance are required.

This cap screw is sized for use in inch-system assemblies requiring a 7/8-9 UNC thread. The fully threaded shank provides maximum thread engagement across the full 2.5-inch grip length, which is particularly useful in through-bolt or close-tolerance joint configurations. Applications include industrial equipment mounting, structural steel connections, heavy machinery assembly, and hydraulic or pneumatic system component attachment where high tensile loads are present.

Key Features

• Grade L9 steel construction with 180,000 psi tensile strength for high-load fastening
• Zinc yellow dichromate finish provides corrosion resistance and identification coating
• Fully threaded shank along the full 2.5-inch length under head
• 7/8-9 UNC thread standard ensures compatibility with inch-system tapped holes and nuts
• 1-5/16 inch hex key size for use with standard open-end, box-end, or socket wrenches
• Sold individually — no minimum bundle requirement

Compatibility

Designed as a direct-fit replacement or new-installation fastener for any inch-system application calling for a 7/8-9 UNC fully threaded hex head cap screw in Grade L9 steel.

Installation Notes

Installation should be performed by qualified trades familiar with fastener torque specifications for Grade L9 hardware — consult the applicable engineering torque table for 7/8-9 UNC fasteners at the required preload. Always ensure the mating tapped hole or nut is rated to the same grade or higher to avoid thread stripping under load. Clean threads before installation and inspect for damage. Follow applicable ASME, OSHA, or equipment OEM guidelines for torquing and joint integrity verification.
