Value Collection 822794MSC Flange Bolt 5/8-11 Unc 4 Inch

Product Description

The VALUE COLLECTION 822794MSC 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 size with a 4-inch length under head and 1.5 inches of partial threading. The smooth flange distributes clamping load across a wider bearing surface without the need for a separate washer. Constructed from Grade 8 alloy steel with a phosphate and oil finish, it delivers high tensile strength and corrosion resistance suited for demanding service environments. Licensed trades and maintenance professionals use this fastener where torque-critical or load-bearing connections are required.

This flange bolt is suited for heavy equipment, automotive drivetrain assemblies, agricultural machinery, and structural fabrication where Grade 8 strength and a smooth flange bearing surface are specified. The 5/8-11 UNC thread standard is one of the most common coarse-thread specifications in inch-series mechanical work. The partially threaded shank provides a smooth grip section that resists shear loading at the joint interface. It meets IFI 111 and SAE J429 standards, making it appropriate for any application specifying those fastener grades.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard inch-series tapped holes and nuts
• Grade 8 alloy steel construction provides high tensile and proof load strength
• Smooth flange eliminates the need for a separate flat washer and distributes clamping force evenly
• Partially threaded shank with 1.5 inches of thread length resists shear forces at the joint
• Phosphate and oil finish improves corrosion resistance and aids in torque consistency during installation
• Meets IFI 111 and SAE J429 fastener standards for Grade 8 hex bolts

Compatibility

Designed as a standard inch-series replacement or new-installation fastener for any application specifying a 5/8-11 UNC Grade 8 partially threaded smooth flange bolt with a 4-inch length under head.

Installation Notes

Installation is performed by mechanical, maintenance, or structural trades using a standard hex drive socket or wrench sized for the 5/8-inch hex head. Always use a calibrated torque wrench and follow the torque specifications provided by the equipment manufacturer or applicable fastener standard for Grade 8 hardware. Inspect threads and the flange seating surface for damage or contamination before installation. Do not reuse fasteners that show signs of thread deformation, corrosion pitting, or yield stretch.
