The 1\/4-20 UNC thread pattern runs the full length of the 5\/8-inch shank, providing consistent grip and load distribution along the entire fastened joint. The 9\/16-inch smooth flange spreads clamping force across a wider area, reducing the risk of surface damage or pull-through in softer materials. Constructed from Grade 8 alloy steel with a phosphate and oil finish, this bolt delivers high tensile strength and baseline corrosion resistance for demanding mechanical and structural assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in industrial machinery, automotive assemblies, structural brackets, and general mechanical fabrication where a high-strength, fully threaded flange bolt is specified. The hex drive allows installation with standard hex wrenches or sockets. The smooth flange face is appropriate where a serrated flange is not required or where surface marring must be avoided. Machinists, maintenance technicians, and assembly mechanics commonly use this bolt in production and repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC fully threaded shank, 5\/8 inches length under head\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch smooth flange diameter distributes clamping load without a separate washer\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish provides corrosion and wear resistance\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible 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 a standard inch-series flange bolt for use in any assembly calling for a 1\/4-20 UNC fully threaded smooth flange bolt in Grade 8 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or mechanical technicians using a hex wrench or socket driver.
