It features a 1\/2-20 UNF thread size, a 1-1\/2 inch length under head, and a 3\/8 inch hex drive. Constructed from alloy steel with a black oxide finish, this fastener delivers reliable corrosion resistance and a clean, low-profile appearance. It is fully threaded along its entire length under head, making it suitable for through-hole and blind-hole fastening where maximum thread engagement is required. Licensed trades, maintenance technicians, and fabricators rely on this type of fastener for precision-fit mechanical connections.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in machinery assembly, HVAC equipment mounting brackets, electrical panel fabrication, and general industrial maintenance. The fine 1\/2-20 UNF thread pitch provides greater tensile strength and finer adjustment than coarse-thread equivalents, making it a preferred choice where vibration resistance or tight tolerances are needed. It is commonly driven with a 3\/8 inch hex key or Allen wrench and is suitable for both new installations and replacement applications in existing equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine thread for higher tensile strength and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1-1\/2 inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 and ASME\/ANSI B18.3 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eConforms to IFI 124 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fastener for industrial and mechanical assemblies requiring a 1\/2-20 UNF hex socket cap screw with a 1-1\/2 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance technicians, millwrights, or mechanical contractors using a 3\/8 inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Do not over-drive; follow the torque requirements specified by the equipment manufacturer for the assembly being serviced.
