It carries a 5\/16-18 UNC thread and measures 2.5 inches in length under the head. The shank is partially threaded, which helps with alignment and load-bearing in through-bolt assemblies. A hot-dipped galvanized finish provides corrosion resistance for outdoor, wet, or exposed environments. This bolt meets ANSI\/ASME B18.2.1 dimensional standards and is sized with a 0.5-inch hex drive for use with standard wrenches or sockets.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for light-to-medium duty fastening in HVAC equipment mounting, plumbing support brackets, electrical enclosure hardware, pool equipment frames, and general structural assemblies. The galvanized finish makes it appropriate for use in outdoor installations and corrosion-prone environments such as rooftop HVAC curbs, pool equipment pads, and exterior utility brackets. It is sold individually but requires a minimum order quantity of 100 units, making it practical for stocking or job-lot purchasing by contractors and maintenance teams.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for compatibility with standard tapped holes and hex nuts\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head suits through-bolt and clearance-hole assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank aids alignment and improves shear load performance\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish resists corrosion in outdoor and wet service conditions\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ANSI\/ASME B18.2.1 dimensional requirements\u003c\/li\u003e\n  \u003cli\u003e0.5-inch hex drive works with standard open-end, box, or socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension UNC hex head bolt for use with 5\/16-18 threaded holes, nuts, and insert hardware in any application specifying an ANSI\/ASME B18.2.1 Grade 2 fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by any trade requiring standard inch-series fasteners.
