Value Collection C703320 Hex Head Cap Screw 9/16-12

Product Description

The VALUE COLLECTION C703320 is a partially threaded hex head cap screw designed for high-strength fastening applications in mechanical, industrial, and structural assemblies. Manufactured from Grade 8 steel with no coating applied, this fastener meets ASME B18.2.1 and SAE J429 standards for dimensional accuracy and tensile strength. The 9/16-12 UNC thread pattern and 3.5-inch length under head make it well suited for bolted connections requiring substantial clamping force. Installed by maintenance technicians, millwrights, and mechanical contractors, this screw is a standard-duty hex cap fastener for demanding load-bearing joints.

This fastener is used in general industrial, mechanical, and structural applications where a high-strength, inch-series UNC bolt is required. The partial threading design allows the unthreaded shank to span joint interfaces, providing a cleaner bearing surface in clearance-fit holes. Typical install scenarios include machinery frames, equipment mounting, and structural steel connections in both commercial and industrial environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 9/16-12 UNC thread compliant with ASME B18.2.1 and SAE J429
• Partially threaded shank provides clean bearing surface through joint stack
• Uncoated finish — suitable for use with separately applied coatings or corrosion protection
• 3.5-inch length under head accommodates substantial material stack thickness
• Sold in a package quantity of 25 with a minimum order quantity of 1

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 9/16-12 UNC Grade 8 fastener per ASME B18.2.1 and SAE J429 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright following applicable torque requirements for Grade 8 fasteners as specified by the equipment manufacturer or relevant standards. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Use a calibrated torque wrench to achieve proper clamp load. Reuse of fasteners that have been torqued to yield is not recommended.
