Value Collection C703600 Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION C703600 is a fully threaded hex head cap screw designed for heavy-duty mechanical and structural fastening applications. It carries a 7/8-9 UNC thread size with a 1-1/2 inch length under head, manufactured from Grade 8 steel in an uncoated finish. Grade 8 steel provides high tensile strength, making this fastener suitable for high-stress assemblies where lower-grade hardware would fail under load. It meets ASME B18.2.1 and SAE J429 standards, confirming dimensional accuracy and mechanical property compliance. Sold in a package quantity of 10, this screw is well suited for maintenance, repair, and production work across industrial and trade environments.

This fastener is used in a wide range of applications including machinery assembly, heavy equipment maintenance, structural steel connections, and industrial fabrication. Its fully threaded design along the full shank length maximizes thread engagement with nuts or tapped holes, making it a reliable choice in applications where clamp load consistency matters. Suitable for use by millwrights, ironworkers, equipment technicians, and general maintenance professionals working with inch-series fastener systems.

Key Features

• 7/8-9 UNC thread form for standard inch-series fastener compatibility
• 1-1/2 inch length under head provides a compact profile for tight-clearance joints
• Grade 8 steel construction delivers high tensile and proof load strength
• Fully threaded shank maximizes thread engagement with mating hardware
• Meets ASME B18.2.1 and SAE J429 standards for dimensional and mechanical compliance
• Uncoated finish — suitable for use as-is or with applied corrosion protection coatings

Compatibility

Designed for use with standard 7/8-9 UNC inch-series hex nuts, flat washers, and lock washers in heavy-duty mechanical and structural fastening applications.

Installation Notes

Installation should be performed by qualified mechanical, maintenance, or construction trades familiar with inch-series fastener torque requirements and proper preload practices. Always verify mating thread condition and apply appropriate lubrication or thread preparation per job specification before final assembly. Do not use an impact driver at full power without a verified torque specification to avoid overloading or stripping threads. Follow applicable industry codes and engineering requirements for the specific joint being fastened.
