Value Collection 97207 Hex Head Cap Screw 7/8-9 X 7 in

Product Description

The VALUE COLLECTION 97207 is a partially threaded hex head cap screw designed for structural and mechanical fastening applications in industrial, commercial, and trade settings. Sized at 7/8-9 thread (7/8-inch diameter, 9 threads per inch UNC) with a 7-inch length under head, this fastener is manufactured from Grade 5 steel and left uncoated for standard bare-metal applications. It conforms to ASME B18.2.1, the governing standard for inch-series hex head screws. The partial threading is appropriate for clamped-joint fastening where a smooth shank is required through one or more members before thread engagement begins. Machinists, millwrights, pipefitters, and general mechanical contractors are the typical installers.

This cap screw is suited for heavy-duty bolted connections in structural steel assemblies, machinery frames, equipment mounting, and pipe-support fabrication. The 7/8-9 UNC thread form is a widely used coarse-thread size in industrial fastening, compatible with standard 7/8-9 hex nuts, washers, and threaded inserts. The uncoated finish is standard for indoor or protected installations where galvanic or corrosion resistance is not a primary requirement. Sold in a package quantity of 10 per order.

Key Features

• 7/8-9 UNC coarse thread — high load-carrying capacity for structural bolted joints
• 7-inch length under head — accommodates thick structural members or stacked assemblies
• Partial threading — smooth shank through clamped members with thread engagement at the end
• Grade 5 steel — meets medium-strength requirements per SAE fastener standards
• ASME B18.2.1 compliant — dimensional conformance for hex head inch-series screws
• Uncoated finish — bare steel, suitable for painted, primed, or indoor protected environments

Compatibility

Designed for use with standard 7/8-9 UNC hex nuts, flat washers, and lock washers in bolted assemblies conforming to inch-series fastener specifications.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or tradesperson familiar with structural bolting procedures. Use a calibrated torque wrench and apply torque values per applicable engineering specifications or the governing standard for the joint classification. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Do not exceed the proof load of a Grade 5 fastener; consult joint design documentation for proper preload requirements.
