Armor Coat UST236005 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The ARMOR COAT UST236005 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 1/2-13 UNC thread and measures 5.5 inches in length under the head, making it suited for applications requiring a longer grip. The screw is partially threaded, which is standard for cap screws of this length. Constructed from alloy steel and finished with an Armor Coat coating for corrosion resistance, it meets ASME B18.3 dimensional standards. A 3/8-inch hex drive socket is required for installation.

This cap screw is used in industrial maintenance, equipment assembly, and mechanical fabrication where a strong, corrosion-resistant fastener is needed. The partially threaded shank provides a bearing surface in the clearance hole, reducing the risk of thread engagement in the wrong location. It is appropriate for use in both shop and field settings where ASME B18.3-compliant fasteners are specified. Installers in HVAC equipment assembly, pump and motor mounting, and general mechanical work will encounter this type of fastener regularly.

Key Features

• 1/2-13 UNC thread size for compatibility with standard 1/2-inch threaded fastener applications
• 5.5-inch length under head accommodates deeper stack-ups and thicker assemblies
• Partially threaded shank per ASME B18.3 standard for proper load distribution
• Alloy steel construction provides high tensile and shear strength
• Armor Coat finish delivers corrosion resistance in demanding environments
• 3/8-inch hex drive for use with standard hex socket tooling

Compatibility

Designed as an ASME B18.3-compliant hex socket cap screw suitable for standard 1/2-13 UNC threaded applications in industrial and mechanical assemblies.

Installation Notes

Installation requires a 3/8-inch hex socket driver or Allen-style bit. Always ensure the mating threaded hole or nut is the correct 1/2-13 UNC specification before driving the fastener. De-energize and lockout any equipment before replacing or installing fasteners in powered assemblies. Do not over-torque; consult the equipment manufacturer's torque specifications for the assembly being serviced.
