Value Collection 011331PR Hex Socket Cap Screw 7/16-14 Unc

Product Description

The VALUE COLLECTION 011331PR is a hex socket cap screw designed for high-strength fastening applications requiring a compact, recessed-drive profile. Machined from alloy steel with a black oxide finish, this fastener measures 3 inches in length under the head and uses a 3/8-inch hex drive. The 7/16-14 UNC thread spec makes it compatible with standard inch-series tapped holes in that size class. It is partially threaded, which helps align mating parts and handle shear loads more effectively than a fully threaded design. Installers in mechanical, industrial, and trade service applications rely on this type of cap screw for equipment assembly, bracket mounting, and structural fastening tasks where a low-profile socket head is required.

This screw is suited for general industrial and mechanical maintenance applications where alloy steel strength and corrosion resistance from black oxide coating are necessary. Typical use cases include mounting brackets, securing mechanical assemblies, and fastening components in enclosed or tight-clearance environments where a hex socket drive is preferred over an external hex. The 7/16-14 UNC thread is a coarse-thread standard widely used in North American equipment manufacturing and field repair work.

Key Features

• 7/16-14 UNC coarse thread for compatibility with standard inch-series tapped holes
• 3 inches length under head for deep fastening in thick stock or stacked assemblies
• 3/8-inch hex socket drive for use with standard Allen keys or hex socket bits
• Partially threaded shank improves shear resistance and part alignment
• Alloy steel construction provides high tensile strength for demanding load applications
• Black oxide finish offers mild corrosion resistance and reduces light reflection in service environments

Compatibility

Designed as a standard ASME/ANSI B18.3 and ASTM A574 hex socket cap screw for use in any application requiring a 7/16-14 UNC partially threaded alloy steel fastener with a 3/8-inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or trade technicians using a 3/8-inch hex key or socket bit. Ensure the mating tapped hole meets 7/16-14 UNC specifications and is free of debris before driving the fastener. Apply thread lubricant or thread-locking compound as appropriate for the application load and vibration requirements. Do not over-torque; consult the equipment manufacturer or applicable fastener torque tables for the correct clamping specification.
