Value Collection 011351P Hex Socket Cap Screw 1/2-13 Unc

Product Description

The Value Collection 011351P is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and trade assembly applications. It features a 1/2-13 UNC thread size, a 3/4-inch length under head, and full threading along its entire shank. The screw is machined from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection on exposed fastener heads. A 3/8-inch hex drive is required for installation. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, confirming compliance with established dimensional and mechanical property requirements for socket cap screws.

This fastener is suited for applications where a recessed hex drive is preferred over a standard hex head, including equipment mounting, fixture assembly, machinery maintenance, and structural connections in tight clearance areas. It is commonly used by machinists, millwrights, maintenance mechanics, and trade professionals working in HVAC equipment assembly, industrial piping supports, and general mechanical installations. The fully threaded configuration ensures consistent thread engagement across the full length under head.

Key Features

• 1/2-13 UNC thread size for reliable engagement in standard UNC-threaded holes
• Fully threaded shank provides maximum thread engagement for the full 3/4-inch length under head
• Alloy steel construction delivers higher tensile strength compared to standard carbon steel fasteners
• Black oxide finish offers moderate corrosion resistance and a low-reflectance appearance
• 3/8-inch hex socket drive compatible with standard hex keys and socket tooling
• Meets ASME/ANSI B18.3 and ASTM A574 standards for socket cap screws

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw suitable for use in any application or assembly requiring an ASME/ANSI B18.3 and ASTM A574 compliant fastener of this thread size and length.

Installation Notes

Installation requires a 3/8-inch hex key or socket driver. Ensure the mating threaded hole or nut is clean and free of debris before driving the screw. De-energize and lock out any equipment before fastener service per applicable OSHA lockout/tagout procedures. Do not exceed the material yield by over-torquing; consult a fastener torque chart for the appropriate value based on alloy steel grade and application.
