Value Collection C703602 Hex Cap Screw 7/8-9 Grade 8

Product Description

The VALUE COLLECTION C703602 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assembly work. Sized at 7/8-9 thread with a 1-3/4 inch length under head, this fastener is manufactured from Grade 8 steel in the uncoated bright finish. Grade 8 designates a high-tensile-strength alloy steel fastener, making it suitable for heavy-load and high-torque joint assemblies. The unified coarse thread (UNC) profile and full threading along the shank length allow for maximum thread engagement in standard tapped holes. This screw conforms to ASME B18.2.1 and SAE J429 standards and is sold in a pack of 10.

This hex head cap screw is appropriate for use across a broad range of mechanical assembly and maintenance applications including equipment mounting, structural connections, and machinery fabrication. The Grade 8 rating makes it a common choice where standard Grade 5 fasteners are insufficient. It is used by millwrights, pipefitters, equipment technicians, and general maintenance trades working on industrial and heavy-duty equipment. The UNC thread pattern is compatible with standard inch-system tapped holes and nuts of the corresponding size and grade.

Key Features

• Conforms to ASME B18.2.1 hex head cap screw dimensional standards
• Sold in a pack of 10 for job-site and shop inventory needs

Compatibility

Designed as a standard inch-system hex head cap screw compatible with 7/8-9 UNC tapped holes and matching Grade 8 hex nuts in general industrial and mechanical assembly applications.

Installation Notes

Installation is performed by qualified mechanical, maintenance, or assembly trades using standard hex wrenches or impact tooling sized for 7/8-inch hex head fasteners. Always verify that the mating tapped hole or nut is rated to an equivalent or higher strength grade to maintain joint integrity. Do not install Grade 8 fasteners in aluminum or softer-material tapped holes without confirming thread-strip resistance. Follow applicable industry torque specifications for 7/8-9 Grade 8 fasteners from the relevant engineering or equipment standard governing the assembly.
