Value Collection 97206 Hex Head Cap Screw 7/8-9 X 6.5 in Grade 5

Product Description

The VALUE COLLECTION 97206 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. Sized at 7/8-9 (7/8 inch diameter with 9 threads per inch, UNC) and 6-1/2 inches in length under the head, this fastener is manufactured from Grade 5 steel with a bright, uncoated finish. It meets ASME B18.2.1 and SAE J429 standards, making it suitable for applications that demand verified mechanical properties and dimensional consistency. Machinists, millwrights, and general tradespeople use this screw where a standard-drive hex fastener with controlled tensile strength is required.

This cap screw is suited for use in heavy equipment assembly, structural steel connections, machine frames, and industrial maintenance repairs where a large-diameter, partially threaded fastener is needed. The partial threading allows for a smooth shank section, which is useful in joint configurations where the unthreaded portion spans the shear plane. Sold in a package quantity of 10, this screw is a practical choice for shop stock or job-site inventory where multiple fasteners of this size are consumed regularly.

Key Features

• 7/8-9 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 6-1/2 inch length under head provides ample grip length for thick material stacks
• Partially threaded shank places threads at the bearing end, keeping the shank smooth across shear planes
• Grade 5 steel construction meets SAE J429 mechanical property requirements for medium-strength fasteners
• Bright, uncoated finish — suitable for dry indoor environments or where field coating will be applied
• Meets ASME B18.2.1 dimensional standards for hex head cap screws

Compatibility

Designed for use with standard 7/8-9 UNC inch-series hex nuts, washers, and tapped holes conforming to ASME and SAE inch-series fastener standards.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a standard hex wrench or impact socket sized for the fastener head. De-energize, depressurize, or otherwise make safe the assembly before disassembly or installation of structural fasteners. Do not substitute Grade 5 fasteners in applications specifying Grade 8 or metric property class equivalents without engineering approval. Follow applicable torque specifications from the equipment manufacturer or relevant structural codes for the specific joint configuration.
