Armor Coat UST235987 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The ARMOR COAT UST235987 is a hex socket cap screw designed for high-strength fastening in mechanical and structural applications. Built from alloy steel and finished with an Armor Coat corrosion-resistant coating, this screw delivers reliable clamping force in demanding environments. It is sized at 1/2-13 UNC thread with a 5/8 inch length under head and is fully threaded. A 3/8 inch hex drive accepts standard hex keys and allen wrenches. It conforms to ASME B18.3 fastener standards, making it suitable for precision assemblies where dimensional consistency matters. Installers in HVAC, plumbing, electrical, and general mechanical trades will find this screw appropriate for equipment panels, brackets, and structural mounts.

This screw is used wherever a recessed hex drive cap screw is required in ferrous or mixed-material assemblies. The fully threaded 1/2-13 UNC configuration suits through-hole and tapped-hole applications in both residential and light commercial equipment. The Armor Coat finish provides added protection against moisture and mild chemical exposure, making it a practical choice for mechanical rooms, rooftop units, and other environments where bare steel fasteners would corrode prematurely.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard tapped holes and hardware
• 5/8 inch length under head for precise grip in shallow-clearance assemblies
• Fully threaded shank maximizes thread engagement in thin material applications
• Armor Coat finish provides corrosion resistance over bare alloy steel
• 3/8 inch hex socket drive accepts standard hex keys for torque-controlled installation
• Conforms to ASME B18.3 for dimensional accuracy and interchangeability

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw suitable for any application requiring a 1/2-13 UNC fully threaded fastener with a 3/8 inch hex drive.

Installation Notes

Installation is performed with a 3/8 inch hex key or allen driver; use a calibrated torque wrench where specified by the equipment manufacturer. De-energize and lock out any equipment before replacing or installing fasteners on live assemblies. Thread engagement should be verified in the receiving material before applying full torque. Follow applicable equipment service manuals and relevant codes for fastener torque requirements.
