It features a 3\/8-16 thread size and a 4-inch length under head, making it well suited for medium-to-heavy-duty mechanical assemblies. The hex socket drive accepts a 5\/16-inch hex key for installation and removal. Manufactured from alloy steel with an Armor Coat finish, this screw delivers the strength and surface protection required in industrial, HVAC equipment, and mechanical system applications. Installation follows ASME B18.3 standards.\u003c\/p\u003e\u003cp\u003eThis socket cap screw is used in a wide range of trade and industrial settings, including HVAC equipment assemblies, mechanical enclosures, pump mounts, and structural fastening where a low-profile cap head is required. The partial threading allows for clamping force over a defined grip length, which is typical in bolted joint applications where the shank bears load. Trades including HVAC technicians, pipefitters, millwrights, and general maintenance professionals will encounter this fastener in equipment service and installation work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 thread size with 4-inch length under head for medium-to-heavy fastening depth\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank conforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003cli\u003eHex socket drive requires a 5\/16-inch hex key for installation\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile strength for demanding mechanical assemblies\u003c\/li\u003e\n\u003cli\u003eArmor Coat finish adds corrosion resistance for extended service life\u003c\/li\u003e\n\u003cli\u003eSocket cap head profile keeps the fastener low-profile in tight clearance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and aftermarket replacement socket cap screw for use in mechanical assemblies, equipment mounting, and structural fastening applications requiring a 3\/8-16 threaded fastener conforming to ASME B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician using a properly sized 5\/16-inch hex key or hex bit driver.
