Value Collection 307408PR Hex Socket Cap Screw 7/16-14 Unc

Product Description

The VALUE COLLECTION 307408PR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural fabrication. This fastener features a 7/16-14 UNC thread size and a 2.5-inch length under head, with a 5/16-inch hex drive socket for installation with a standard Allen key or hex bit driver. Constructed from alloy steel and finished with a black oxide coating, it meets ASTM A574 requirements for mechanical properties and dimensional tolerances. It is commonly installed by millwrights, machinists, and maintenance technicians working with heavy equipment or structural components.

This cap screw is suited for use in bolted joints requiring a recessed drive head, including machine frames, jigs, fixtures, and mechanical assemblies where a flush or countersunk profile is needed. The partial threading allows the unthreaded shank to act as a locating or shear surface in close-tolerance applications. Sold in multiples of 5, making it appropriate for both small repair jobs and recurring production needs.

Key Features

• 7/16-14 UNC thread for compatibility with standard inch-series tapped holes
• 2.5-inch length under head for use in thicker material stacks
• Partially threaded shank provides shear resistance and precise location in close-tolerance bores
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 5/16-inch hex drive accepts standard Allen keys and hex bit sockets

Compatibility

Designed as an OEM-style replacement or general-use fastener for standard 7/16-14 UNC tapped holes in industrial machinery, structural fabrications, and mechanical assemblies.

Installation Notes

Installation requires a 5/16-inch hex key or socket bit driver. Ensure the mating tapped hole is clean, free of debris, and cut to the correct UNC thread specification before installation. Apply thread lubricant or anti-seize compound as required by the joint design to achieve accurate clamp load. Follow applicable torque guidelines from ASME or the equipment manufacturer for 7/16-14 UNC fasteners at the specified material grade.
