Value Collection 97211 Hex Head Cap Screw 7/8-9 X 9 in Grade 5

Product Description

The VALUE COLLECTION 97211 is a partially threaded hex head cap screw sized 7/8-9 x 9 inches, manufactured from Grade 5 steel with an uncoated finish. Conforming to ASME B18.2.1, this fastener uses a Unified National Coarse (UNC) thread form and is measured by length under head. Grade 5 steel provides a reliable tensile strength suitable for general structural and mechanical assembly applications. The uncoated surface is standard for installations where coating is applied post-assembly or where bare steel is acceptable for the environment. Machinists, millwrights, and maintenance technicians commonly specify this fastener for industrial and commercial equipment assembly.

This cap screw is suited for use in heavy equipment assembly, structural steel connections, general manufacturing, and maintenance applications where a large-diameter, partially threaded hex fastener is required. The 7/8-9 UNC thread size and 9-inch length under head make it appropriate for through-bolting thick material sections. It is sold in packages of 10, making it practical for small-volume jobs or repair work requiring matched fasteners.

Key Features

• 7/8-9 UNC thread size for broad compatibility with standard tapped holes and nuts
• 9-inch length under head accommodates thick material stack-ups
• Grade 5 steel construction meets standard medium-strength fastener requirements
• Partially threaded shank provides a smooth bearing surface through material layers
• Conforms to ASME B18.2.1 dimensional standard for hex head cap screws
• Uncoated finish suitable for post-installation coating or bare-steel applications

Compatibility

Designed as a standard ASME B18.2.1 inch-series hex head cap screw compatible with 7/8-9 UNC tapped holes and standard hex nuts of the same thread designation.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using standard hex wrenches or impact tooling sized for a 7/8-9 hex head. Always verify hole alignment and thread condition before driving the fastener. Follow applicable torque specifications from the equipment manufacturer or relevant structural codes for Grade 5 fasteners. Inspect threads for damage and ensure mating nut grade is compatible before final assembly.
