Value Collection 451076BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451076BR is a fully threaded hex head cap screw engineered for high-strength fastening applications in industrial, mechanical, and structural assemblies. It carries a 1-1/2-12 UNF thread specification with a 3-inch length under head, manufactured from Grade 8 steel with a bright uncoated finish. Grade 8 fasteners meet demanding load and shear requirements, making this screw appropriate for heavy equipment, machinery mounts, and structural joints where standard-grade hardware is insufficient. Weighing 2.45 pounds, this is a substantial fastener suited for professional tradespeople and industrial maintenance technicians working with precision inch-series thread standards.

This cap screw is used in applications requiring a fine-thread UNF fastener at 1-1/2-12 thread size, including heavy machinery assembly, hydraulic equipment mounting, industrial fabrication, and structural mechanical connections. The fully threaded shank provides maximum thread engagement across the full 3-inch length under head. The bright uncoated finish is suited for indoor and controlled-environment installations where corrosion exposure is limited, or where a specific coating will be applied post-installation. Licensed machinists, millwrights, and maintenance mechanics commonly specify this fastener type.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength requirements
• 1-1/2-12 UNF (Unified National Fine) thread form for precise engagement and resistance to loosening
• Fully threaded shank delivers maximum thread engagement over the full 3-inch length under head
• Bright uncoated finish maintains dimensional accuracy and is compatible with post-installation coatings
• Conforms to ASME B18.2.1 dimensional standards for inch-series hex head cap screws
• 2-1/4-inch hex key size for use with standard heavy-duty hex wrenches and impact tooling

Compatibility

Designed as an OEM-style replacement or specification-grade fastener for assemblies calling for a 1-1/2-12 UNF fully threaded hex head cap screw conforming to ASME B18.2.1 in Grade 8 steel.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with high-strength fastener procedures. Always verify thread engagement depth and mating material compatibility before installation. Use a calibrated torque wrench sized for the 2-1/4-inch hex drive to achieve proper clamp load without over-stressing the fastener. Inspect mating threads for damage or contamination before assembly.
