Armor Coat UST236006 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The ARMOR COAT UST236006 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade service environments. Built from alloy steel and finished with an Armor Coat coating for corrosion resistance, this screw features a 1/2-13 UNC thread size and measures 6 inches in length under the head. It uses a 3/8-inch hex drive and is partially threaded, making it well suited for clamping and load-bearing connections where thread engagement needs to terminate before the full shank length. Licensed mechanics, maintenance technicians, and industrial tradespeople are the primary installers of this fastener type.

This screw is appropriate for use in heavy equipment assembly, structural fastening, machine mounting, and similar applications where an alloy steel cap screw with corrosion-resistant finish is specified. It meets ASME B18.3 standards, confirming dimensional accuracy and drive geometry compliance. The partial threading design allows for shoulder-style clamping when passing through clearance holes in one or more mating components before engaging a tapped bore or nut.

Key Features

• 1/2-13 UNC thread form for standard coarse-thread compatibility
• 6-inch length under head for deep fastening or multi-layer assemblies
• 3/8-inch hex socket drive for use with standard Allen keys or hex bits
• Partially threaded shank for shoulder clamping and clearance-hole applications
• Alloy steel construction for high tensile strength
• Armor Coat finish for enhanced corrosion protection over bare steel
• Conforms to ASME B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for applications specifying a 1/2-13 UNC hex socket cap screw conforming to ASME B18.3.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated torque wrench and appropriate 3/8-inch hex drive tool. Always verify thread engagement depth and confirm the tapped hole or nut is clean and free of debris before driving. De-energize or lock out any equipment in accordance with applicable OSHA lockout/tagout procedures before fastener service. Do not reuse fasteners that show signs of thread damage, galling, or coating failure.
