Value Collection C39044 Flange Bolt 5/8-11 Unc Grade 8

Product Description

The VALUE COLLECTION C39044 is a smooth flange bolt designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 5/8-11 UNC thread with a 1-1/4 inch length under the head and is fully threaded along that length. The integrated smooth flange measures 1-21/64 inches (1.3281 inches) in diameter, distributing clamping load across a wider surface without requiring a separate washer. Constructed from Grade 8 alloy steel and left uncoated, this bolt meets IFI 111 and SAE J429 standards. It is driven with a standard hex tool and is sold in packages of 10.

This bolt is suited for heavy-duty bolted joint applications where a washer-face flange is preferred for load distribution. Typical uses include machinery assembly, equipment mounting, and structural fastening in automotive, manufacturing, and general industrial settings. The Grade 8 alloy steel construction makes it appropriate for high-stress connections where tensile strength and shear resistance are critical factors. Installers working under SAE J429 or IFI 111 specifications will find this bolt a direct fit for compliant assemblies.

Key Features

• 5/8-11 UNC thread form, fully threaded over 1-1/4 inch length under head
• Integrated smooth flange at 1-21/64 inches diameter eliminates need for a separate flat washer
• Grade 8 alloy steel construction for high tensile strength in demanding applications
• Hex drive head compatible with standard wrenches and sockets
• Uncoated finish suitable for use where coating is not specified or where field coating will be applied
• Meets IFI 111 and SAE J429 fastener standards

Compatibility

Designed as a standard UNC hex flange bolt for use in any application requiring a 5/8-11 thread and conforming to IFI 111 and SAE J429 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or assembler familiar with torque specifications appropriate to Grade 8 fasteners and the joint material being fastened. Always verify thread engagement and ensure mating threads are clean and undamaged before assembly. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts not rated for the application load. Follow applicable industry standards and engineering specifications for final torque values, as these are determined by joint design and are not supplied with this part.
