Value Collection 822348MSC Flange Bolt 3/4-10 Unc 3-1/2 in Grade 8

Product Description

The VALUE COLLECTION 822348MSC is a smooth flange bolt designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 3/4-10 UNC thread profile with a 1-3/4 inch thread length and measures 3-1/2 inches under the head. The integral smooth flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, this bolt delivers the tensile strength and corrosion resistance required in demanding service environments. Installation is driven by a standard hex drive. Tradespeople and maintenance professionals working with heavy equipment, structural steel, or machinery will find this bolt ready for critical fastening tasks.

This flange bolt is suited for use in general industrial maintenance, OEM equipment assembly, and mechanical infrastructure applications where high-strength UNC fasteners are specified. The smooth flange style is appropriate where a clean bearing surface is required against the mating material without a serrated locking edge. It conforms to IFI 111 and SAE J429 standards, making it appropriate for engineered assemblies where fastener grade documentation is required.

Key Features

• 3/4-10 UNC thread — coarse unified national thread standard for broad tool and hardware compatibility
• 3-1/2 inch length under head with 1-3/4 inch thread engagement length — partially threaded shank for shear-load applications
• Smooth flange diameter of 1-19/32 inches (1.5938 inches) provides integrated load-bearing surface
• Grade 8 alloy steel construction for high tensile and proof-load requirements
• Phosphate and oil finish for baseline corrosion protection and lubricity during installation
• Meets IFI 111 and SAE J429 fastener standards

Compatibility

Designed as a standard 3/4-10 UNC smooth flange bolt for use in industrial and mechanical assemblies requiring Grade 8 alloy steel fasteners per IFI 111 and SAE J429 specifications.

Installation Notes

Installation is performed with a standard hex wrench or socket drive sized for a 3/4-10 bolt head. Always confirm the mating thread specification and hole clearance before installation. Apply torque values per the relevant engineering standard or assembly drawing for Grade 8 fasteners at this thread size. De-energize, depressurize, or otherwise isolate the assembly before servicing any bolted joint under load.
