It features a 5\/16-18 UNC thread size and measures 3.5 inches in length under the head. The fastener is partially threaded and accepts a 1\/4-inch hex drive. Constructed from alloy steel with a black oxide finish, it offers solid tensile strength and basic corrosion resistance suitable for interior and light-duty service environments. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where dimensional and mechanical property conformance is required.\u003c\/p\u003e\n\u003cp\u003eThis hex socket cap screw is used across a broad range of trade and industrial applications including HVAC equipment assembly, mechanical panels, pump mounting, electrical enclosures, and general structural fastening. The socket drive style allows installation in tight spaces where a wrench cannot swing freely. It is commonly installed by HVAC technicians, millwrights, pipefitters, electricians, and general maintenance professionals. Minimum order quantity is 25 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for standard inch-series fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head for deeper grip in thick material applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides stronger clamping force on joined materials\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive allows use in confined spaces with a hex key or bit driver\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex socket cap screw conforming to ASME\/ANSI B18.3, suitable for use wherever this thread size and drive style are specified in mechanical or structural fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/4-inch hex key or socket bit driver.
