It features a 5\/8-11 UNC thread form and measures 1-3\/4 inches in length under the head. The integrated smooth flange spreads clamping load across a 1-21\/64 inch diameter bearing face. Manufactured from Grade 8 alloy steel, this bolt meets IFI 111 and SAE J429 standards, making it suitable for structural and high-strength mechanical assemblies. The hex drive head accepts standard socket or wrench tooling. The finish is bright and uncoated.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in industrial, mechanical, and structural applications where a one-piece flange fastener simplifies assembly and reduces part count. Partial threading allows for full shank engagement in clearance holes before thread engagement begins, which is common in bolted joints with thick material stacks. Maintenance technicians, millwrights, and general mechanical contractors will find this bolt appropriate for equipment mounting, brackets, frames, and similar structural connections requiring a Grade 8 rated fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread form — coarse thread for fast assembly and strong engagement\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head with partial threading for clearance-hole applications\u003c\/li\u003e\n  \u003cli\u003eIntegrated smooth flange diameter of 1-21\/64 inches distributes clamping load without a washer\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high-tensile-strength applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for dry or indoor service environments\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 IFI 111 and SAE J429 compliant smooth flange bolt for use in inch-series bolted assemblies requiring a 5\/8-11 UNC Grade 8 partially threaded fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a hex socket or open-end wrench sized for the fastener head.
