The ARMOR COAT UST237435 is a hex socket cap screw designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. Manufactured from alloy steel with an Armor Coat finish for corrosion resistance, this screw features a 7/16-14 UNC thread and a 3/4-inch length under head. The 3/8-inch hex drive accommodates a standard hex key or Allen driver. It conforms to ASME B18.3, making it a recognized fastener for precision mechanical assemblies. This screw is fully threaded, providing maximum thread engagement throughout the fastened joint. HVAC technicians, pipefitters, electricians, and mechanical contractors regularly use fasteners of this type when securing equipment panels, brackets, and structural components.
This cap screw is suited for use in residential and commercial mechanical installations where a secure, recessed-drive fastener is required. Common applications include equipment mounting, bracket fabrication, panel assembly, and structural fastening on HVAC units, electrical enclosures, and plumbing equipment frames. The Armor Coat finish provides a layer of protection against moisture and mild corrosive environments, making it a practical choice for mechanical rooms and outdoor equipment installations.
Designed as an OEM-style replacement or supplemental fastener for any application requiring a 7/16-14 UNC hex socket cap screw per ASME B18.3 dimensional standards.
Installation requires a 3/8-inch hex key or appropriate socket driver. Always de-energize and lock out equipment before accessing panels or assemblies secured by this fastener. Apply appropriate thread lubricant or anti-seize compound if required by the equipment manufacturer. Follow applicable mechanical and structural codes for fastener torque and joint requirements.
