It features a 3\/8-16 UNC thread size and a 1-inch length under head, making it well-suited for medium-duty bolted connections where a flush or low-profile socket-drive fastener is required. Manufactured from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance. Drive engagement is achieved through a 5\/16-inch hex socket. This screw meets ASME B18.3 and ASTM A574 standards. Sold in packs of 25.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a wide range of trade and industrial applications including HVAC equipment assemblies, electrical enclosures, plumbing fixture mounting, and general mechanical fabrication. It is appropriate for both shop and field use wherever a recessed hex-drive fastener is specified. The black oxide coating reduces surface reflectivity and provides light corrosion protection in dry or mildly humid indoor environments. Installation requires a 5\/16-inch hex key or socket bit driver.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for standard unified coarse-thread engagement\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the entire 1-inch length under head\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch internal hex drive for high-torque socket wrench or Allen key installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides light corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standard for socket head cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex socket cap screw suitable for general mechanical assemblies, equipment panels, and structural connections that specify an ASME B18.3 socket head cap screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a mechanic, millwright, or licensed trade professional using a 5\/16-inch hex key, T-handle, or socket bit. Ensure the mating tapped hole is clean and free of debris before threading. De-energize all equipment and relieve any system pressure before removing or replacing fasteners in live assemblies.
