This bolt features a 3\/8-16 UNC thread specification with a 2-1\/2 inch length under head and 1 inch of thread engagement on the partially threaded shank. Manufactured from Grade 8 alloy steel with a phosphate and oil finish for corrosion resistance, it meets SAE J429 standards. The integrated 13\/16 inch smooth flange distributes clamping load evenly without the need for a separate washer, making it a preferred choice in tight-tolerance assemblies where load bearing and alignment matter.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is suited for use in heavy equipment, automotive, HVAC equipment mounting, and general industrial fabrication where Grade 8 strength and UNC threading are specified. The smooth flange face is appropriate for applications requiring a clean bearing surface against softer materials or coated components. It is installed by maintenance technicians, millwrights, and mechanical contractors working to manufacturer torque specifications for 3\/8-16 Grade 8 fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank with 1 inch of thread length for positive shank grip in bolted joints\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load ratings per SAE J429\u003c\/li\u003e\n  \u003cli\u003eSmooth 13\/16 inch flange distributes clamping load without a separate washer\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish provides baseline corrosion resistance and lubricity for consistent torque values\u003c\/li\u003e\n  \u003cli\u003eHex drive head for use with standard wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC Grade 8 smooth flange bolt for use in any application specifying SAE J429 Grade 8 inch-series fasteners with a hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical technicians following the applicable torque specifications for 3\/8-16 Grade 8 fasteners as defined by the equipment manufacturer or relevant structural standards.
