The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. This bolt measures 3 inches in length under head and is fully threaded on a 5\/16-18 UNC coarse thread. It is manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. Electricians, HVAC technicians, plumbers, and general mechanical contractors reach for this type of fastener when a separate washer would be impractical or when vibration resistance is a priority.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for light-to-medium structural connections in residential and commercial mechanical systems. Typical applications include mounting brackets, equipment panels, ductwork supports, electrical enclosures, and machinery frames where UNC coarse thread engagement and vibration-resistant clamping are required. The fully threaded shank provides maximum thread engagement across the full grip range, making it adaptable to varying material stack-up thicknesses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated flange resists loosening under vibration without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e3 inches length under head suits a range of material thicknesses\u003c\/li\u003e\n  \u003cli\u003e0.68 inch flange diameter distributes clamping load over a wider bearing area\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in typical indoor environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 dimensional standards for hex head fasteners\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 for use in any application requiring ASME B18.6.3 and SAE J429 compliant Grade 5 fasteners with a hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a standard hex socket or open-end wrench sized for the hex head.
