Value Collection 451095PR Hex Head Cap Screw 7/16-20 X 8 in

Product Description

The VALUE COLLECTION 451095PR is a Grade 8 steel hex head cap screw designed for high-strength fastening applications. It features a 7/16-20 UNF thread with a length under head of 8 inches and partial threading along the shank. Grade 8 steel provides significantly higher tensile strength than standard hardware-grade fasteners, making this screw appropriate for structural and mechanical assemblies subject to heavy load or vibration. The bright, uncoated finish leaves the steel bare without any plating or treatment. This fastener is manufactured to ASME B18.2.1 dimensional standards and is driven with a 5/8-inch hex key or wrench.

This cap screw is suited for industrial, mechanical, and equipment assembly applications where a partially threaded, high-strength inch-series fastener is required. Partial threading preserves an unthreaded grip length along the shank, which is important in joints where the bolt body must span a clearance hole without thread engagement in that region. Typical users include maintenance technicians, millwrights, and equipment builders working in manufacturing, agricultural equipment, heavy machinery, and structural assembly environments.

Key Features

• Grade 8 steel construction for high tensile strength in demanding assemblies
• Partially threaded shank provides a clean grip length through clearance holes
• 7/16-20 UNF thread form for fine-pitch engagement and superior clamping force
• 8-inch length under head accommodates thick stack-ups and long through-bolt applications
• Bright uncoated finish — bare steel with no plating
• Manufactured to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 7/16-20 UNF tapped hole or nut requiring a Grade 8 fastener per ASME B18.2.1 specifications.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or equipment assemblers using a 5/8-inch open-end, box-end, or socket wrench. Always ensure mating threads are clean and free of debris before installation. Torque to the appropriate specification for Grade 8 fasteners at this diameter as defined by the applicable engineering standard or equipment manufacturer documentation. Do not substitute a lower-grade nut or tapped hole material that cannot support the clamping load of a Grade 8 fastener.
