Value Collection 97225 Hex Head Cap Screw 1-8x6 Grade 5

Product Description

The VALUE COLLECTION 97225 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in mechanical, structural, and industrial assemblies. Manufactured from Grade 5 steel with an uncoated finish, this fastener measures 1-8 thread size with a 6-inch length under the head. The Unified National Coarse (UNC) thread form is the standard for general-purpose inch-series fastening. Produced to ASME B18.2.1 dimensional standards, this screw delivers consistent head geometry and thread engagement for reliable torque loading. It is a common choice for machinists, millwrights, and maintenance technicians working on equipment frames, flanges, and structural connections.

This cap screw is suited for use in residential and commercial mechanical installations, equipment fabrication, and maintenance repair operations where a large-diameter, coarse-thread inch-series fastener is required. The partial threading allows the unthreaded shank to act as a locating or bearing surface in close-tolerance bores, making it appropriate for bolted joint assemblies where shank engagement is part of the design. Sold in a package quantity of 10, it is well-suited for shop stock, field service kits, and MRO procurement.

Key Features

• Grade 5 steel construction for high tensile strength in heavy-duty fastening
• Partial threading with unthreaded shank for use as a locating surface in close-tolerance bores
• UNC thread form for compatibility with standard inch-series nuts and tapped holes
• Meets ASME B18.2.1 dimensional standards for consistent head geometry and thread tolerances
• Uncoated finish suitable for applications where plating or corrosion coating is not required
• Packaged in quantities of 10 for shop stock and MRO use

Compatibility

Designed as a standard inch-series hex head cap screw for use with 1-8 UNC tapped holes and compatible hex nuts in general mechanical and structural assemblies.

Installation Notes

Installation should be performed by qualified millwrights, machinists, or maintenance technicians following applicable torque specifications for Grade 5 fasteners as referenced in engineering standards. Always ensure the mating tapped hole or nut is clean and free of debris before assembly. Use a properly sized hex wrench or socket to avoid rounding the head. Do not over-torque or substitute this fastener in applications requiring higher-grade material without engineering review.
