Manufactured from Grade 8 steel with a zinc-plated finish, this bolt provides high tensile strength and corrosion resistance. The integrated serrated flange distributes clamping load across a wider surface area and bites into the mating material to resist loosening under vibration. The 5\/16-18 UNC thread pattern runs fully along the 1\/2-inch length under head, with a flange diameter of 0.68 inches. This fastener is installed by maintenance technicians, millwrights, equipment assemblers, and trade professionals working with structural or mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for mechanical assemblies, equipment frames, brackets, and structural connections where a flanged fastener replaces the need for a separate washer. The serrated bearing surface makes it a practical choice in high-vibration environments such as HVAC equipment mounting, electrical panel brackets, plumbing fixture framing, and light industrial machinery. The 5\/16-18 UNC thread standard is widely used in inch-system assemblies across residential and commercial trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction delivers high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eSerrated flange eliminates the need for a separate lock washer and resists vibration loosening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for indoor and light-duty outdoor applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the 1\/2-inch length under head maximizes thread engagement\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 0.68 inches spreads clamping force over a wider bearing area\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J429 standards for dimensional and mechanical compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series serrated flange bolt for use in any assembly requiring a 5\/16-18 UNC threaded fastener with an integrated flanged bearing surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a standard hex driver or wrench sized for the hex head.
