It features a Phillips drive and is manufactured from steel with a zinc-plated finish for basic corrosion resistance. The thread size follows the unified coarse (UNC) standard at 5\/16-18, meaning 5\/16 inches in diameter with 18 threads per inch. The 2.5-inch measurement is taken under the head, per ASME B18.6.3 and SAE J82 specifications. This screw is installed by HVAC technicians, electricians, plumbers, and general maintenance trades wherever a standard inch-system machine screw is required.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for light-to-medium duty mechanical assemblies in residential and commercial applications. Its pan head profile provides a low-profile bearing surface with a large contact area, making it a common choice for sheet metal enclosures, equipment panels, brackets, and structural hardware. The Phillips drive is compatible with standard #3 Phillips bits and drivers widely used across trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length measured under the head per ASME B18.6.3\u003c\/li\u003e\n  \u003cli\u003ePan head with Phillips drive for standard tool access\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eGrade J82 per SAE J82 and ASME B18.6.3 standards\u003c\/li\u003e\n  \u003cli\u003eNo washer — clean seating directly against the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system machine screw suitable for use wherever a 5\/16-18 x 2.5-inch pan head Phillips fastener is specified.
