Value Collection 451500BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451500BR is a heavy-duty hex head cap screw designed for high-strength bolted assemblies in industrial, construction, and mechanical applications. Manufactured to ASME B18.2.1 standards, this fastener features a 1-1/8-12 UNF thread and measures 13 inches under the head. Grade 8 steel construction delivers tensile strength well above standard hardware grades, making it suitable for demanding structural and machine applications. The bright, uncoated finish is appropriate for controlled environments where corrosion exposure is minimal. A licensed mechanic, millwright, or maintenance technician would typically source this screw for heavy equipment assembly or structural bolting.

This cap screw fits applications requiring a fine-thread, large-diameter fastener with partial threading along its length. Partial threading is common in bolted joints where the unthreaded shank provides shear strength across the joint interface. Typical use cases include machinery frames, press assemblies, heavy steel fabrication, and industrial equipment maintenance. It is sold individually and is appropriate for both planned maintenance stock and single-use repair scenarios.

Key Features

• Grade 8 steel construction for high-tensile-strength bolted connections
• 1-1/8-12 UNF fine thread for precise clamping force control
• Partially threaded shank provides shear strength across joint interfaces
• Conforms to ASME B18.2.1 dimensional standards
• Bright, uncoated finish suitable for controlled or indoor environments
• 1-11/16 inch hex key size for use with standard heavy-duty wrenching tools

Compatibility

Designed as a standard 1-1/8-12 UNF Grade 8 hex head cap screw per ASME B18.2.1, suitable for use in heavy industrial equipment, structural steel assemblies, and mechanical systems requiring a large-diameter fine-thread fastener.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with high-strength fastener procedures. Always de-energize and lock out equipment before replacing structural fasteners on machinery. Use a properly rated torque wrench sized for 1-11/16 inch drive to achieve consistent clamping load without guessing. Inspect mating threads and bearing surfaces for damage before installation.
