Value Collection 451440BR Hex Head Cap Screw 1-1/8-7 X 13 in

Product Description

The VALUE COLLECTION 451440BR is a heavy-duty hex head cap screw sized 1-1/8-7 x 13 inches, manufactured from Grade 8 steel with a bright, uncoated finish. Partially threaded along the shank, this fastener follows UNC thread standards and is produced to ASME B18.2.1 specifications. At 3.95 pounds, it is suited for high-load structural and mechanical assemblies where tensile strength and dimensional consistency are critical. Installation requires a 1-11/16-inch hex key or wrench. Maintenance crews, millwrights, and mechanical contractors working on heavy equipment, steel fabrication, or industrial machinery will find this a reliable, standard-compliant choice.

This cap screw is used in applications demanding a high-strength fastener with partial threading, such as through-bolted flanges, heavy structural connections, machinery frames, and equipment mounts. The partial thread design allows the unthreaded shank to bear shear loads while the threaded section engages the nut or tapped hole. It is appropriate for both shop and field installations in industrial, commercial, and heavy-equipment contexts where Grade 8 steel strength and ASME dimensional compliance are required.

Key Features

• Grade 8 steel construction for high tensile and proof load capacity
• Partially threaded shank designed to handle shear loads at the joint interface
• UNC thread form at 1-1/8-7 for broad nut and hardware compatibility
• Meets ASME B18.2.1 dimensional standards for consistent fitment
• Bright, uncoated finish — suitable for dry indoor applications or where coating-specific plating will be applied on site
• 1-11/16-inch hex drive wrench size for standard tooling

Compatibility

Designed as an OEM-style or maintenance replacement hex head cap screw for industrial assemblies requiring a 1-1/8-7 UNC partially threaded fastener conforming to ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or structural ironworker using a properly rated torque wrench and a 1-11/16-inch hex socket or open-end wrench. De-energize, lockout, and tagout any associated equipment before fastener removal or installation per applicable OSHA and facility procedures. Do not substitute a lower-grade fastener in a Grade 8 application. Follow the joint designer's torque specifications and any applicable AISC or equipment OEM guidelines for proper preload.
