Value Collection 822793MSC Flange Bolt 5/8-11 Unc 3 in Grade 8

Product Description

The VALUE COLLECTION 822793MSC is a smooth flange bolt designed for high-strength fastening applications requiring a wide bearing surface without a separate washer. It features a 5/8-11 UNC thread with a 3-inch length under head and is partially threaded at 1.5 inches of thread engagement. Manufactured from Grade 8 alloy steel with a phosphate and oil finish for corrosion resistance, this bolt is rated to IFI 111 and SAE J429 standards. The hex drive and smooth flange design allow straightforward torquing with standard hand or power tools in structural, mechanical, and industrial assembly work.

This flange bolt is suited for structural and mechanical assemblies where a built-in flange distributes clamping load across a larger surface area. Typical applications include heavy equipment fabrication, automotive and powertrain assemblies, machinery mounting, and industrial framework connections. The Grade 8 alloy steel construction makes it appropriate for high-load and vibration-prone environments. It is commonly installed by machinists, millwrights, maintenance technicians, and mechanical assembly professionals working to inch-standard specifications.

Key Features

• 5/8-11 UNC thread form for compatibility with standard inch-series tapped holes and nuts
• 3-inch length under head with 1.5-inch partial thread for shank grip in joint stack-ups
• Grade 8 alloy steel construction for high tensile and proof load capacity
• Smooth flange diameter of 1.3281 inches acts as an integral washer to spread clamping load
• Phosphate and oil finish provides baseline corrosion and galling resistance
• Meets IFI 111 and SAE J429 fastener standards for dimensional and mechanical conformance

Compatibility

Designed as a standard inch-series smooth flange bolt for use in any application requiring a 5/8-11 UNC partially threaded fastener conforming to IFI 111 and SAE J429 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical technicians using a hex wrench or socket driver. Always confirm the mating tapped hole or nut is rated for Grade 8 loading before assembly. Clean and inspect the flange bearing surface and mating material before torquing to avoid debris-induced misreads on torque values. Refer to applicable torque tables for 5/8-11 UNC Grade 8 fasteners per your governing specification or engineering documentation.
