Value Collection 451096BR Hex Cap Screw 1-1/2-12 X 7 in Grade 8

Product Description

The VALUE COLLECTION 451096BR is a heavy-duty hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel with a bright, uncoated finish, this fastener delivers exceptional tensile and proof load strength compared to lower-grade hardware. The 1-1/2-12 UNF thread is partially threaded with a 7-inch length under head, making it well suited for bolted assemblies where a precise grip length is required. It conforms to ASME B18.2.1 dimensional standards, ensuring dimensional consistency for use in engineered and specification-driven installations. Weighing 4.37 pounds, this is a large-format fastener intended for structural or heavy mechanical assembly work.

This cap screw is used in industrial, heavy equipment, structural steel, and mechanical assembly applications where high-clamp-load fasteners are specified. The fine 12-thread-per-inch UNF pitch provides greater thread engagement strength and finer adjustment compared to coarse-thread equivalents, making it a preferred choice in vibration-prone environments or where precise torque values are critical. Typically installed by machinists, millwrights, ironworkers, or maintenance mechanics on large-scale equipment frames, dies, fixtures, and structural connections.

Key Features

• Grade 8 steel construction for high tensile strength fastening
• 1-1/2-12 UNF fine-thread pitch for superior thread engagement and vibration resistance
• Partially threaded shank provides a clean grip zone in the fastened assembly
• Bright, uncoated finish suitable for use in dry or controlled environments
• Conforms to ASME B18.2.1 dimensional standards for specification-grade installations
• 2-1/4-inch hex key drive size compatible with standard heavy-hex tooling

Compatibility

Designed as an ASME B18.2.1 specification-grade replacement or new-installation hex head cap screw for assemblies requiring a 1-1/2-12 UNF partially threaded fastener in Grade 8 steel.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with Grade 8 fastener torque requirements. Always clean and inspect mating threads before assembly, and use calibrated torque tooling to achieve the specified clamp load for the joint design. Do not reuse fasteners that show signs of thread damage, stretching, or corrosion. A 2-1/4-inch heavy-hex socket or wrench is required for installation.
