Value Collection 451102PS Hex Cap Screw 1/2-13 X 7 in Grade 8

Product Description

The VALUE COLLECTION 451102PS is a partially threaded hex head cap screw designed for high-strength fastening in demanding industrial and mechanical applications. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener delivers the tensile strength required for heavy-duty bolted assemblies. The 1/2-13 UNC thread pattern and 7-inch length under head make it well suited for through-bolt applications where extended grip length is needed. A 3/4-inch hex key drive allows for installation with standard wrench tooling. It conforms to ASME B18.2.1 dimensional standards, ensuring dimensional consistency across replacement and production use.

This cap screw is used in structural, mechanical, and equipment assembly applications where Grade 8 strength ratings are specified. Partial threading provides a smooth shank section that resists shear loads along the grip length. Typical installations include machinery frames, steel fabrication, heavy equipment mounting, and industrial maintenance work. Trades commonly working with this fastener include millwrights, ironworkers, mechanical contractors, and maintenance technicians in manufacturing and construction environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank resists shear stress in bolted joints
• 1/2-13 UNC thread form for broad compatibility with standard nuts and tapped holes
• 7-inch length under head accommodates thick stack-ups and through-bolt assemblies
• Bright uncoated finish suitable for use with added corrosion protection if required
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/2-13 UNC tapped hole or standard hex nut meeting ASME dimensional requirements.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using appropriate torque specifications for Grade 8 fasteners as referenced in applicable engineering standards. Always inspect mating threads and hardware for damage before assembly. Use a calibrated torque wrench to achieve proper clamp load. Do not reuse fasteners that show signs of thread damage, stretching, or corrosion.
