It features a 5\/8-11 UNC thread size with a 2-1\/4 inch length under head and partial threading measuring 2-1\/4 inches. The integrated smooth flange distributes clamping load across a wider surface area, reducing the need for a separate washer. Manufactured from Grade 8 alloy steel in an uncoated finish, this bolt meets IFI 111 and SAE J429 standards. It is installed using a hex drive and is suited for heavy-duty mechanical and structural assemblies.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is appropriate for use in industrial, mechanical, and trade-service applications requiring a high-strength UNC fastener. The smooth flange face is compatible with standard flange joint assemblies and is commonly used in equipment mounting, structural connections, and machinery maintenance. Its Grade 8 alloy steel construction makes it suitable for high-load environments encountered in HVAC equipment installation, fabrication, and general mechanical trade work. This part is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread size with 2-1\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eSmooth flange with 1-21\/64 inch (1.3281 inch) flange diameter provides integrated bearing surface\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for precise clamping in structural applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; meets IFI 111 and SAE J429 fastener standards\u003c\/li\u003e\n  \u003cli\u003eHex drive for standard socket or wrench installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for assemblies requiring a 5\/8-11 UNC smooth flange bolt with Grade 8 alloy steel and IFI 111 or SAE J429 compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or trade professional using a calibrated torque wrench and the appropriate hex socket.
