It features a 1\/4-20 thread size and a 4-inch length under head, with a socket cap head driven by a 3\/16-inch hex key. The screw is manufactured from alloy steel and finished with an Armor Coat corrosion-resistant coating, making it suited for environments where standard zinc or plain finishes would corrode prematurely. Meets ASME B18.3 dimensional standards for socket head cap screws.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in general mechanical assemblies, equipment maintenance, and fixture fabrication where a low-profile cap head and internal hex drive are required. The partial threading allows for shoulder-style clamping force in through-hole and clearance-hole applications. Typical installers include millwrights, pipefitters, HVAC equipment technicians, and general maintenance mechanics working on industrial or commercial machinery.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 thread size with 4-inch length under head for deep fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for precise clamping in clearance-hole assemblies\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength\u003c\/li\u003e\n  \u003cli\u003eArmor Coat finish offers enhanced corrosion resistance over standard finishes\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for secure torque transfer with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fastener for mechanical assemblies requiring a 1\/4-20 partially threaded socket cap screw conforming to ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by maintenance mechanics or trade technicians using a 3\/16-inch hex key or Allen driver.
