Value Collection 451175BR Hex Head Cap Screw 7/8-14

Product Description

The VALUE COLLECTION 451175BR is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It measures 7/8-14 thread size with an 8-1/2 inch length under head, machined to Grade 8 steel for exceptional tensile strength. The bright, uncoated finish is standard for applications where additional corrosion protection is applied separately or where bare steel is specified. Manufactured to ASME B18.2.1, this fastener meets recognized dimensional and performance standards for inch-series hex cap screws. It is a common choice for heavy equipment assembly, fabrication shops, and maintenance work requiring a reliable high-grade fastener.

This cap screw fits applications calling for a UNF (Unified National Fine) thread pattern in the 7/8-14 designation, which provides finer thread engagement than coarse-series fasteners in the same diameter. The partially threaded shank makes it suitable for clamping applications where an unthreaded grip length is needed to span joint interfaces cleanly. Maintenance technicians, millwrights, and fabricators working on heavy machinery, hydraulic assemblies, or structural connections will find this fastener appropriate for standard inch-series bolted joints requiring Grade 8 performance.

Key Features

• Grade 8 steel construction for high tensile strength in demanding fastening applications
• 7/8-14 UNF thread — fine thread series for improved clamping force and vibration resistance
• Partially threaded shank provides a clean grip zone across joint interfaces
• Meets ASME B18.2.1 dimensional standard for inch-series hex cap screws
• Bright, uncoated finish — compatible with field-applied coatings or bare steel specifications
• 5/8 inch hex key size for standard hex wrench or socket installation

Compatibility

Designed as an OEM-style replacement or standard-service hex cap screw for inch-series bolted assemblies requiring a 7/8-14 UNF thread, 8-1/2 inch length under head, and Grade 8 steel strength classification per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with inch-series fastener torque procedures. Always consult the equipment manufacturer's torque specifications for the application — Grade 8 fasteners require appropriate torque values that should not be assumed without reference to engineering data. Ensure mating threaded holes or nuts are clean, undamaged, and of compatible thread class before installation. Follow applicable mechanical or structural codes for the specific assembly.
