Value Collection 15379PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 15379PR is a hex socket cap screw designed for high-strength fastening in industrial and mechanical assemblies. It features a 1/2-13 UNC thread and measures 4.5 inches in length under the head. The fastener is partially threaded and driven with a 3/8-inch hex key. Constructed from alloy steel with a black oxide finish, it resists corrosion and maintains surface hardness under load. This screw meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for demanding structural and machine applications. Machinists, millwrights, and maintenance technicians commonly specify this type of fastener for equipment assembly and repair.

This cap screw is suited for general industrial fastening applications where a recessed hex drive and high tensile strength are required. It is commonly used in machine frames, fixtures, tooling plates, and heavy equipment assemblies. The black oxide coating reduces friction during installation and provides mild corrosion resistance in indoor and sheltered environments. It is sold individually per package, with a minimum order quantity of 10 pieces.

Key Features

• 1/2-13 UNC thread for standard unified coarse thread engagement
• 4.5-inch length under head for deep fastening in thick stock
• 3/8-inch hex drive for positive torque transfer with standard hex keys or socket drivers
• Partially threaded shank reduces thread engagement in the bearing zone
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers mild corrosion resistance and reduced galling

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw conforming to ASME/ANSI B18.3, ASTM A574, and IFI 124, suitable for use in any application accepting that thread standard and drive type.

Installation Notes

Installation is performed using a 3/8-inch hex key or socket driver. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Apply appropriate thread lubricant or thread locker as required by the assembly specification. Follow applicable mechanical codes and equipment manufacturer torque guidelines for 1/2-13 UNC fasteners when finalizing the joint.
