Value Collection 015373PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 015373PR is a partially threaded hex socket cap screw designed for high-strength bolted assemblies. It features a 1/2-13 UNC thread size and measures 3-1/4 inches in length under the head, driven by a 3/8-inch hex key. Constructed from alloy steel with a black oxide finish coating, this fastener delivers corrosion resistance and reduced surface reflectivity suited to industrial and mechanical applications. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for structural and machine assembly work where torque and load requirements are demanding.

This socket cap screw is used in general industrial fabrication, machine frames, equipment mounting, and structural fastening where a recessed-drive fastener is preferred over a hex head bolt. The alloy steel construction handles high clamping loads in both static and dynamic applications. It is a common choice for maintenance technicians, millwrights, and fabricators working on equipment assemblies, jigs, fixtures, and mechanical structures across light and heavy manufacturing environments.

Key Features

• 1/2-13 UNC thread — coarse thread series for general-purpose fastening in steel and iron
• 3-1/4 inches length under head — partially threaded shank for shoulder grip in blind or clearance holes
• 3/8-inch hex drive socket — compatible with standard hex keys and socket drivers
• Alloy steel construction — supports high tensile and proof load requirements per ASTM A574
• Black oxide finish — provides mild corrosion resistance and low-glare surface treatment
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 1/2-13 UNC partially threaded fastener with a 3/8-inch hex drive.

Installation Notes

Installation is performed with a 3/8-inch hex key or allen socket driver. Ensure mating threads are clean and free of debris before installation. Always torque to the specifications required by the assembly design engineer or equipment manufacturer. Alloy steel fasteners with black oxide finish may require lubrication to achieve accurate torque-tension results in critical joints.
