Sized at 1\/2-13 thread with a 1-3\/4 inch length under head, it is manufactured from Grade 8 steel and finished with a zinc yellow dichromate coating that provides corrosion resistance. The UNC thread form and full threading along the shank make it suitable for through-bolt and fully engaged nut applications. It conforms to ASME B18.2.1 and SAE J429 standards, making it appropriate wherever a traceable, specification-grade fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in heavy equipment assembly, machinery mounting, structural steel connections, and automotive or powertrain applications where Grade 8 tensile strength is specified. The 1\/2-13 UNC thread is one of the most widely used coarse-thread sizes in inch-based mechanical systems. Maintenance technicians, millwrights, mechanics, and fabricators regularly specify Grade 8 fasteners at this size for applications involving vibration, shear loads, or elevated clamping-force requirements. Minimum order quantity is 25 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets SAE J429 mechanical property requirements for high-strength fastener service\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and is visually identifiable as a Grade 8 fastener\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank allows maximum thread engagement across the full 1-3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread conforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for compatibility with standard SAE tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a specification-grade replacement or stock fastener for any inch-system assembly requiring a 1\/2-13 UNC fully threaded hex head cap screw in Grade 8 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanics, millwrights, or maintenance technicians using standard 3\/4 inch hex drive tooling appropriate for a 1\/2-13 fastener.
