Value Collection 97203 Hex Head Cap Screw 7/8-9 X 5 in Grade 5

Product Description

The VALUE COLLECTION 97203 is a partially threaded hex head cap screw designed for structural and mechanical fastening applications. Manufactured from Grade 5 steel with an uncoated finish, this fastener measures 7/8-9 thread size with a 5-inch length under the head. The Unified National Coarse (UNC) thread form and conformance to ASME B18.2.1 make it a reliable choice for standard inch-system bolted connections. Maintenance mechanics, millwrights, pipefitters, and general contractors regularly reach for this size when assembling heavy equipment, flanges, structural steel, or machinery frames.

This cap screw is suited for a wide range of industrial and commercial fastening tasks where a partially threaded grip length is required to clamp unthreaded material between the bearing surface and the nut. Typical applications include equipment mounting, structural steel connections, heavy machinery assembly, and general mechanical maintenance. The 7/8-9 UNC thread form is one of the most common heavy-duty inch fastener sizes across manufacturing and construction environments. Sold in a package quantity of 25, the 97203 is appropriate for both single-job use and bench stock replenishment.

Key Features

• Grade 5 steel construction provides a minimum tensile strength suitable for medium-duty structural and mechanical fastening
• Partially threaded shank allows proper clamping force across unthreaded material thickness
• 7/8-9 UNC thread form for compatibility with standard inch-system nuts and tapped holes
• Uncoated finish for use in dry indoor environments or where a field-applied coating will be added
• Meets ASME B18.2.1 dimensional standard for hex head cap screws
• Package quantity of 25 supports both small repairs and moderate volume fastening work

Compatibility

Designed for use with any standard 7/8-9 UNC hex nut or tapped hole meeting ASME B18.2.1 inch-series dimensional requirements.

Installation Notes

Installation is performed with a standard hex (six-point) socket or open-end wrench sized for a 7/8-9 heavy hex or standard hex head. Always verify thread engagement depth and ensure mating nut or tapped hole is clean and free of damage before assembly. Torque to the fastener manufacturer or joint design specification — do not substitute generic torque values. Follow applicable codes such as AISC or ASME standards for structural or pressure-related bolted joints.
