Armor Coat UST236009 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The ARMOR COAT UST236009 is a hex socket cap screw engineered for demanding fastening applications where corrosion resistance and high tensile strength are required. Built from alloy steel with an Armor Coat finish, this fastener measures 8 inches in length under the head and features a 1/2-13 UNC thread form with partial threading. The 3/8 inch hex drive socket allows precise torque application using standard hex keys or Allen-style drive tools. It conforms to ASME B18.3, the recognized standard for socket cap screws in North American industrial and mechanical applications. Maintenance technicians, millwrights, and mechanical contractors working on structural assemblies, machinery, and equipment enclosures routinely specify this fastener type.

This screw is suited for use in industrial, commercial, and heavy mechanical installations where a secure, high-strength cap screw connection is needed. The partial threading allows for strong clamping force in thicker material stack-ups, making it a practical choice for equipment mounting, structural bracketing, and machine assembly work. The Armor Coat finish provides a protective barrier against corrosion, extending service life in environments exposed to moisture or mild chemicals.

Key Features

• 1/2-13 UNC thread size for compatibility with standard inch-series tapped holes
• 8 inches of length under head accommodates thick material assemblies
• Partial threading provides strong clamping force across material stack-ups
• 3/8 inch hex socket drive for precise torque application
• Alloy steel construction for high tensile strength
• Armor Coat finish for corrosion protection in demanding environments
• Conforms to ASME B18.3 fastener standard

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 1/2-13 UNC partially threaded cap screw with an 8 inch length under head.

Installation Notes

Installation is typically performed by millwrights, mechanical contractors, or maintenance technicians using a 3/8 inch hex key or socket drive tool. Ensure the receiving tapped hole is clean, properly sized, and free of debris before installation. Follow applicable torque specifications for the joint material and alloy steel fastener grade per engineering or equipment documentation. Do not exceed the designed thread engagement depth of the mating component.
