Armor Coat UST236003 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The ARMOR COAT UST236003 is a hex socket cap screw designed for high-strength fastening applications in mechanical, industrial, and trade installations. Built from alloy steel with an Armor Coat finish for corrosion resistance, this screw features a 1/2-13 UNC thread size and measures 4.5 inches in length under the head. It is partially threaded and driven with a 3/8-inch hex drive. Manufactured to ASME B18.3 standards, it is suited for structural and equipment assembly work where a reliable, torque-capable socket-head fastener is required. Weighing 0.28 pounds, it is well-suited for use in demanding environments where finish durability matters.

This screw is appropriate for use in commercial and industrial settings where alloy steel fasteners conforming to ASME B18.3 are specified. Typical applications include machinery assembly, structural bracketing, equipment mounting, and other bolted joint configurations where a hex socket drive is preferred for torque control and flush or recessed installation. The partial threading allows for secure clamping force across thicker material stacks, making it a practical choice for heavy-duty mechanical assemblies handled by millwrights, pipefitters, electricians, and general maintenance trades.

Key Features

• 1/2-13 UNC thread size for common industrial and mechanical applications
• 4.5-inch length under head with partial threading for strong clamping in thick material
• Alloy steel construction for high tensile strength and durability
• Armor Coat finish provides corrosion resistance in demanding environments
• 3/8-inch hex socket drive compatible with standard hex keys and socket tools
• Manufactured to ASME B18.3 dimensional and tolerance standards

Compatibility

Designed as an OEM-style replacement or standard hex socket cap screw for mechanical and industrial bolted joint assemblies requiring 1/2-13 UNC thread specifications per ASME B18.3.

Installation Notes

Installation should be performed by qualified trade personnel using a calibrated torque wrench and the appropriate 3/8-inch hex key or socket bit. De-energize and lock out any equipment before servicing fastened assemblies per applicable OSHA and facility safety procedures. Do not exceed the fastener's rated torque specification as determined by your engineering reference or applicable mechanical code. Inspect threads for damage before installation and ensure mating threads are clean and free of debris.
