Value Collection 822686MSC Flange Bolt 1/4-20 Unc 3/4 in Grade 8

Product Description

The VALUE COLLECTION 822686MSC is a smooth flange bolt designed for applications requiring a load-distributing bearing surface without the need for a separate washer. The bolt features a 1/4-20 UNC thread at 3/4 inch length under head, fully threaded along its entire shank. A 9/16 inch smooth flange diameter spreads clamping load across the joint face. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it meets SAE J429 standards for mechanical and material requirements. This fastener is suited for high-strength bolting tasks in mechanical assemblies, brackets, and equipment where vibration resistance and joint integrity are priorities.

This bolt is used in a wide range of industrial, automotive, and mechanical assembly applications where a flanged bearing surface is preferred over a flat washer setup. The fully threaded configuration allows maximum thread engagement even in shallow or thin-material applications. Grade 8 alloy steel construction makes it appropriate for high-load, high-stress joints in both OEM manufacturing and field repair scenarios. Installers working in HVAC equipment assembly, electrical enclosure mounting, and general mechanical fabrication will find this fastener compatible with standard 1/4-20 UNC tapped holes and clearance patterns.

Key Features

• 1/4-20 UNC thread form for compatibility with standard unified coarse-thread tapped holes
• Fully threaded shank at 3/4 inch length under head for maximum thread engagement
• 9/16 inch smooth flange diameter distributes clamping load without a separate washer
• Grade 8 alloy steel construction for high tensile and proof load requirements
• Phosphate and oil finish provides baseline corrosion resistance and lubricity
• Meets SAE J429 standard for grade identification and mechanical properties

Compatibility

Designed for use in any application requiring a 1/4-20 UNC fully threaded smooth flange bolt conforming to SAE J429 Grade 8 specifications. Sold in multiples of 100.

Installation Notes

Installation is performed with a standard hex driver or wrench sized for the bolt head. Ensure the mating tapped hole or nut is rated to Grade 8 or equivalent to avoid thread stripping under load. De-energize all electrical systems and relieve any stored mechanical pressure before servicing assemblies that include fasteners of this type. Do not mix Grade 8 fasteners with lower-grade nuts or inserts in high-stress joints.
