Value Collection C703304 Hex Head Cap Screw 9/16-12 Grade 8

Product Description

The VALUE COLLECTION C703304 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This screw features a 9/16-12 UNC thread size, a 1.5-inch length under head, and is manufactured from Grade 8 steel, making it suitable for demanding load-bearing connections. The uncoated finish is appropriate for use in dry or controlled environments where corrosion protection is not required. Each screw conforms to ASME B18.2.1 dimensional standards, ensuring reliable fitment with standard hex tooling. Sold in packs of 50, this fastener is a practical choice for mechanics, millwrights, and maintenance technicians working with high-tensile bolted joints.

This hex head cap screw is suited for heavy-duty bolted connections in machinery, equipment frames, and structural steel applications. Grade 8 fasteners are commonly used where high tensile and proof load ratings are required, such as in drivetrain components, press frames, and industrial mounting assemblies. The fully threaded shank allows engagement along the entire length under head, making it particularly useful in thinner material applications or where maximum thread engagement is needed with a nut or threaded insert.

Key Features

• 9/16-12 UNC thread for compatibility with standard inch-series hex nuts and threaded holes
• Fully threaded shank provides maximum thread engagement along the full 1.5-inch length under head
• Grade 8 steel construction meets high tensile, proof load, and yield strength requirements
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment and interchangeability
• Uncoated finish suitable for dry service environments or applications where a secondary coating will be applied
• Sold in packs of 50 for efficient stocking and job-site use

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 9/16-12 UNC threaded nuts, inserts, and tapped holes per ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by qualified mechanics or maintenance technicians using a standard hex wrench or socket sized for a 9/16-12 bolt head. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Grade 8 fasteners require appropriate torque values determined by the equipment manufacturer or applicable engineering standards — do not use generic torque tables without confirming the joint design requirements. Always de-energize or lock out equipment before servicing fastened assemblies on powered machinery.
