Value Collection 97212 Hex Head Cap Screw 7/8-9 X 10 in Grade 5

Product Description

The VALUE COLLECTION 97212 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in mechanical, structural, and industrial assemblies. It carries a 7/8-9 UNC thread size and measures 10 inches under the head, making it suited for through-bolt and long-reach clamping jobs. Manufactured from Grade 5 steel with an uncoated finish, it meets ASME B18.2.1 and SAE J429 standards. Machinists, millwrights, pipefitters, and general contractors install this fastener wherever a high-strength inch-series hex bolt is called for.

This fastener is used across a wide range of trade and industrial applications including equipment mounting, structural steel connections, machinery frames, and HVAC equipment bases. The 7/8-9 coarse thread profile provides strong clamping force and resists cross-threading during installation. The partial threading allows the unthreaded shank to bear shear loads in bolted joints, a common requirement in mechanical and structural work. Sold in a package quantity of 10, this screw suits both single-repair and small-batch production needs.

Key Features

• 7/8-9 UNC coarse thread for reliable engagement and strong clamping force
• 10-inch length under head for long-reach and through-bolt applications
• Grade 5 steel construction meets SAE J429 minimum proof load and tensile strength requirements
• Partially threaded shank supports shear load transfer in bolted connections
• Uncoated finish — suitable for use as-installed or with field-applied coatings
• Conforms to ASME B18.2.1 dimensional standard for inch-series hex cap screws

Compatibility

Designed as a standard inch-series hex head cap screw for use with 7/8-9 UNC nuts and tapped holes in steel, iron, and compatible structural assemblies per ASME B18.2.1.

Installation Notes

Installation is performed by machinists, millwrights, or general mechanics using standard open-end, box-end, or socket wrenches sized for a 7/8-9 hex fastener. Follow applicable torque tables for Grade 5 fasteners from the governing specification or engineering documentation for the assembly. Inspect threads and mating surfaces for damage before installation. Do not reuse fasteners that show signs of thread galling, elongation, or corrosion.
