Value Collection C703324 Hex Head Cap Screw 9/16-12 X 4 in

Product Description

The VALUE COLLECTION C703324 is a Grade 8 steel hex head cap screw with a 9/16-12 UNC thread and a 4-inch length under head. Partially threaded and left uncoated, this fastener is built for high-strength bolted joints where a hardened steel fastener is required. Grade 8 designation indicates a tensile strength suitable for demanding mechanical and structural assemblies. It conforms to ASME B18.2.1, the standard governing the dimensional requirements for inch-series hex head cap screws. Installers and maintenance technicians working in industrial, mechanical, or equipment fabrication settings will find this fastener appropriate for applications requiring reliable clamping force and resistance to loosening under load.

This cap screw is suited for use in general mechanical assembly, industrial equipment maintenance, and structural bolting applications where inch-series hardware is specified. The 9/16-12 UNC thread is a standard coarse-thread configuration commonly found in steel fabrication, heavy equipment, and machinery. The partial threading leaves a smooth shank section under the head, which provides shear strength and precise fit in clearance holes. Sold in packages of 25, this fastener is appropriate for trade shops, maintenance crews, and facilities technicians who require bulk quantities of high-grade hardware.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 9/16-12 UNC coarse thread for broad compatibility with standard inch-series nuts and tapped holes
• 4-inch length under head for use in thicker joint stacks requiring extended reach
• Partially threaded shank provides shear resistance and accurate fit in clearance holes
• Uncoated finish for bare steel applications or where a coating will be applied in the field
• Conforms to ASME B18.2.1 dimensional standard for inch-series hex head cap screws

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 9/16-12 UNC nuts, tapped holes, and standard hex tooling in mechanical and structural bolting applications.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or mechanical assemblers using standard 15/16-inch hex tooling. Ensure mating threads are clean and free of debris before installation. Torque to the value specified by the joint design engineer or equipment manufacturer for Grade 8 fasteners of this size. Do not substitute Grade 8 hardware with lower-grade fasteners in applications where Grade 8 is specified.
