Sized at 1\/2-13 UNC with a 2-1\/4 inch length under head, this bolt is partially threaded with a 1-1\/4 inch thread length. It is manufactured from Grade 8 alloy steel, making it suitable for high-strength fastening tasks. The smooth flange measures 1-5\/64 inches (1.0781 inches) in diameter and distributes clamping load evenly across the joint surface. The bolt arrives uncoated and conforms to IFI 111 and SAE J429 standards. Hex drive allows installation with standard wrenches or sockets.\u003c\/p\u003e\u003cp\u003eThis bolt is commonly used in industrial, agricultural, and heavy equipment assembly where Grade 8 strength is required and a flanged bearing surface improves load distribution. Typical applications include machinery frames, structural steel connections, and equipment mounting brackets. The partially threaded shank provides a strong grip in the unthreaded region, which is useful in joint configurations where shear loading is a factor. Sold in a package quantity of 10 per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size with 1-1\/4 inch thread length, partially threaded shank\u003c\/li\u003e\n\u003cli\u003e2-1\/4 inch length under head for deep fastening applications\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high-strength performance\u003c\/li\u003e\n\u003cli\u003eSmooth flange diameter of 1-5\/64 inches (1.0781 inches) for integrated bearing surface\u003c\/li\u003e\n\u003cli\u003eHex drive compatible with standard 3\/4 inch wrenches and sockets\u003c\/li\u003e\n\u003cli\u003eMeets IFI 111 and SAE J429 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex flange bolt suitable for use in any application requiring Grade 8 alloy steel strength and IFI 111 or SAE J429 compliant hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with standard hand tools or power tools fitted with a 3\/4 inch hex socket.
