Value Collection C703244 Hex Head Cap Screw 1/2-13 X 8 in

Product Description

The VALUE COLLECTION C703244 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in industrial and mechanical assemblies. Manufactured from Grade 8 steel with no finish coating, this fastener delivers high tensile strength suited for demanding structural and equipment connections. It features a 1/2-13 UNC thread size and a length under head of 8 inches. Conforming to ASME B18.2.1, the screw meets established dimensional standards for inch-series hex head cap screws. Machinists, millwrights, and maintenance technicians commonly specify Grade 8 fasteners where higher proof loads are required versus Grade 5 or lower-grade alternatives.

This cap screw is appropriate for use in industrial machinery, structural steel connections, heavy equipment frames, and fabrication assemblies where high-strength inch-series fasteners are required. The 1/2-13 UNC thread pattern is widely used across North American manufacturing and maintenance applications. The uncoated finish is suitable for applications where a secondary coating or plating will be applied post-installation, or where environmental exposure is controlled. Partial threading on the shank provides a smooth bearing surface in clearance holes, which is preferred in certain joint designs over fully threaded fasteners.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength for demanding fastening applications
• 1/2-13 UNC thread form matches standard inch-series tapped holes and nuts
• 8 inches length under head accommodates thick-section assemblies and stacked material joints
• Partially threaded shank delivers a smooth bearing surface in clearance-hole joints
• Conforms to ASME B18.2.1 for consistent dimensional accuracy
• Uncoated finish allows for field-applied coatings or use in controlled environments

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, coupling nuts, and tapped holes conforming to inch-series thread standards in industrial and structural assemblies.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using standard hex wrenches or impact tools sized for 1/2-inch fasteners. Ensure mating threads and clearance holes are clean and free of debris before assembly. Apply thread lubricant or thread-locking compound as required by the joint specification. Follow applicable torque specifications from the fastener manufacturer or engineering drawings, as torque values vary by joint material, lubrication, and application requirements not defined in this listing.
