Sized at 5\/8-11 UNC with a 3-1\/2 inch length under head, this bolt is partially threaded with 1-1\/2 inches of thread engagement. The integrated smooth flange measures 1-21\/64 inches (1.3281 inches) in diameter and distributes clamping load without a separate washer. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it delivers high tensile strength and corrosion resistance suitable for heavy-duty fastening. This fastener meets IFI 111 and SAE J429 standards and is installed with a standard hex drive.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in industrial, mechanical, and structural assemblies where a flanged fastener eliminates the need for a loose washer and provides a clean, load-distributing interface. Common applications include equipment frames, brackets, machinery mounts, and fabricated steel assemblies. The Grade 8 rating makes it appropriate for high-stress connections in both OEM manufacturing and field repair work. Machinists, millwrights, and maintenance technicians are the typical installers in these settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread size with 1-1\/2 inches of partial threading for controlled engagement depth\u003c\/li\u003e\n  \u003cli\u003eIntegrated smooth flange at 1-21\/64 inches diameter distributes clamping load without a separate washer\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and proof load ratings\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish offers baseline corrosion protection and lubricity during installation\u003c\/li\u003e\n  \u003cli\u003eHex drive head for use with standard wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eMeets IFI 111 and SAE J429 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and replacement fastener for any application requiring a 5\/8-11 UNC partially threaded smooth flange bolt with a 3-1\/2 inch length under head and Grade 8 strength rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with inch-series fastener torque requirements for Grade 8 hardware. Always clean and inspect mating threads before installation.
