It features a 5\/16-18 UNC thread with a 3\/4-inch length under head and is fully threaded from head to tip. The integrated serrated flange measures 0.68 inches in diameter, distributing clamp load across a wider bearing surface while the serrations resist loosening under vibration. Manufactured from Grade 8 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. It is driven with a hex tool and suits applications where a separate washer is not practical or desired.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for use in automotive, industrial, and mechanical assembly applications where vibration resistance and high tensile strength are required. The serrated flange face bites into the mating surface to prevent rotation and back-off without an additional locking element. It is typically installed by machinists, maintenance technicians, and assembly line workers dealing with steel-on-steel joints, brackets, enclosures, and frame connections. The zinc plating provides baseline corrosion resistance for indoor and light-duty outdoor use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange diameter of 0.68 inches distributes load and locks against loosening\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC shank allows engagement at any position along the thread length\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers corrosion resistance for general-use environments\u003c\/li\u003e\n  \u003cli\u003eHex drive head works with standard sockets and wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J429 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC serrated flange bolt suitable for use in any application requiring a Grade 8 fully threaded hex flange fastener per ASME B18.6.3 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a hex socket or open-end wrench sized for a standard 5\/16-inch hex flange bolt head.
