Armor Coat UST235955 Hex Socket Cap Screw 3/8-16

Product Description

The ARMOR COAT UST235955 is a hex socket cap screw designed for precision fastening applications in mechanical, HVAC, plumbing, and industrial assemblies. Manufactured from alloy steel and finished with an Armor Coat coating for corrosion resistance, this fastener meets ASME B18.3 standards. The screw features a 3/8-16 UNC thread size, a 7/8-inch length under head, and a 5/16-inch hex drive socket. It is fully threaded along its length, making it suitable for through-hole and tapped-hole installations where maximum thread engagement is required. Licensed tradespeople and industrial maintenance technicians are the primary installers of this hardware.

This hex socket cap screw is suited for use in equipment assemblies, panel mounting, machinery maintenance, and structural component fastening across residential and commercial trade applications. Its Armor Coat finish provides added protection against rust and environmental exposure, making it a practical choice for installations in mechanical rooms, outdoor enclosures, and high-humidity environments. Sold individually with a minimum order quantity of 100 units, this screw is intended for bulk trade procurement.

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies, equipment panels, and structural components requiring a 3/8-16 UNC hex socket cap screw per ASME B18.3.

Installation Notes

Installation is performed by licensed tradespeople or qualified maintenance technicians using a 5/16-inch hex key or hex socket bit driver. Always de-energize and lock out equipment before servicing fasteners on electrical or mechanical assemblies. Verify thread engagement and torque requirements against the equipment manufacturer specifications before final tightening. Do not overtighten, as alloy steel fasteners may strip tapped threads in softer base materials.
