Armor Coat UST235994 Socket Cap Screw 1/2-13 2 in

Product Description

The ARMOR COAT UST235994 is a 1/2-13 socket cap screw with a 2-inch length under head, manufactured from alloy steel with an Armor Coat finish for corrosion resistance. It features a hex socket drive requiring a 3/8-inch hex key and is fully threaded along its entire length. This fastener meets ASME B18.3 standards and is suited for high-strength bolted joint applications in mechanical assemblies, industrial equipment, and fabrication work. Licensed trades and maintenance technicians working on structural or mechanical connections regularly specify this screw type where consistent clamping force and a low-profile head are required.

This socket cap screw is used in applications that demand a strong, reliable fastener in confined spaces where a hex socket drive is preferred over an external drive. The fully threaded configuration provides consistent thread engagement across the full 2-inch shank length, making it appropriate for through-bolting and tapped-hole applications. It is commonly installed in equipment mounting, machinery assembly, and maintenance repair operations across industrial, commercial, and heavy mechanical settings.

Key Features

• 1/2-13 thread size with 2-inch length under head for deep thread engagement
• Fully threaded shank for maximum thread contact in tapped holes
• Alloy steel construction provides high tensile strength
• Armor Coat finish improves corrosion resistance in demanding environments
• 3/8-inch hex socket drive for precise torque application in tight spaces
• Meets ASME B18.3 dimensional standards

Compatibility

Designed as a standard 1/2-13 socket cap screw per ASME B18.3, compatible with any tapped or through-hole application specifying a 1/2-13 fully threaded socket cap fastener.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or mechanical tradespeople using a 3/8-inch hex key or Allen-head driver. Verify thread engagement depth in tapped holes before applying final torque, and ensure mating threads are clean and free of debris. Follow applicable fastener torque specifications from the equipment manufacturer or relevant ASME guidelines. Never substitute fastener grade without confirming load requirements.
