Armor Coat UST235964 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The ARMOR COAT UST235964 is a hex socket cap screw designed for fastening applications that require a recessed drive and a secure, corrosion-resistant finish. This screw features a 3/8-16 UNC thread, a 3-inch length under head, and a 5/16-inch hex drive. It is manufactured from alloy steel and finished with an Armor Coat coating for added surface protection. The partial threading design allows for precise clamping and is well-suited for bolted joint applications in mechanical assemblies. Installation is performed using a 5/16-inch hex key or Allen driver and conforms to ASME B18.3 dimensional standards.

This screw is used in general industrial, mechanical, and trade assembly applications where a socket-drive fastener is required. It is appropriate for residential and commercial maintenance work, equipment fabrication, and structural fastening tasks. The 3/8-16 UNC coarse thread pitch is a common standard size used across a wide range of metal fabrication, HVAC equipment mounting, plumbing fixture assembly, and general mechanical work. Installers in multiple trades will encounter this fastener size in field service and repair scenarios.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 3-inch length under head for deep grip and solid clamping force
• 5/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Partially threaded shank for accurate joint alignment and clamping
• Alloy steel construction for high tensile strength in demanding applications
• Armor Coat finish provides corrosion resistance in exposed or harsh environments
• Meets ASME B18.3 dimensional standard

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 3/8-16 UNC partially threaded fastener with a 5/16-inch hex drive.

Installation Notes

Installation requires a 5/16-inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the torque rating of the mating material, and avoid over-torquing, which can strip threads or damage the workpiece. This fastener should be installed by qualified personnel familiar with standard mechanical assembly practices.
