It features a 1\/2-13 UNC thread with a 1-inch length under head and is fully threaded from bearing surface to tip. The integrated serrated flange — 1.07 inches in diameter — distributes clamping load over a wider surface area while the serrations bite into the mating surface to resist loosening under vibration. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. Hex drive makes installation straightforward with standard hand or power tools.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for general industrial, automotive, and mechanical assembly applications where vibration resistance is required without a separate lock washer. The serrated flange replaces the need for a toothed or split lock washer in many standard installations. Typical applications include equipment frames, brackets, enclosures, and mounting assemblies across manufacturing, maintenance, and repair environments. The zinc-plated finish provides basic corrosion resistance for indoor and mildly exposed conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange (1.07 inches diameter) distributes load and resists back-out under vibration\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1\/2-13 UNC, 1-inch length under head for maximum thread engagement in thin stock\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in typical indoor environments\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard sockets, wrenches, and hex-drive power tools\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC serrated flange bolt for use in any application requiring an ASME B18.6.3 and SAE J429 compliant fastener with an integrated serrated flange bearing surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by maintenance technicians, millwrights, or mechanical assemblers using standard hex sockets or open-end wrenches. Always verify the mating thread is clean and free of damage before installation. The serrated flange is designed to seat directly against the workpiece — do not add a flat or lock washer between the flange and the mating surface, as this defeats the anti-loosening function.
