Value Collection 011349PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 011349PR is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread size with a 5/8-inch length under the head and is fully threaded along its entire shank. The screw is driven with a 3/8-inch hex key. Manufactured from alloy steel with a black oxide finish, it delivers solid corrosion resistance in moderate environments while maintaining the tensile strength required for demanding bolted joints. Machinists, millwrights, and maintenance technicians install this type of fastener across a wide range of equipment and fixture work.

This socket cap screw is suited for general industrial fastening where a recessed hex drive is preferred over an external hex head. Common applications include machine frames, jigs, fixtures, tooling plates, and equipment enclosures. The black oxide finish reduces surface corrosion and minimizes light reflection in precision or optical environments. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where documented fastener grade compliance is required. It is sold individually but must be ordered in multiples of 50.

Key Features

• 1/2-13 UNC thread size for standard inch-series fastening
• 5/8-inch length under head, fully threaded shank
• 3/8-inch hex socket drive for use with standard hex keys or socket drivers
• Alloy steel construction for high tensile strength
• Black oxide finish for moderate corrosion resistance and low reflectivity
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 1/2-13 UNC threaded fastener with a recessed hex drive and a 5/8-inch length under head.

Installation Notes

Install using the correct 3/8-inch hex key or socket bit to avoid rounding the drive socket. De-energize and lock out any equipment before replacing or tightening fasteners on live machinery per applicable safety procedures. Apply thread lubricant or thread-locking compound as required by the assembly specification. Torque to the assembly engineer's specified value for 1/2-13 alloy steel fasteners — do not estimate torque without a reference specification.
