Value Collection 822695MSC Flange Bolt 5/16-18 Unc 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION 822695MSC is a smooth flange bolt designed for high-strength fastening applications in mechanical, HVAC, and industrial assemblies. It features a 5/16-18 UNC fully threaded shank with a length under head of 1.5 inches and an 11/16-inch (0.6875 inches) flange diameter. The built-in 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 offers enhanced tensile strength and corrosion resistance compared to lower-grade hardware. It is driven by a standard hex head and conforms to SAE J429. Licensed tradespeople and maintenance technicians install this fastener across a range of structural and equipment-mounting applications.

This bolt is suited for use in residential and commercial mechanical system assemblies, equipment mounting, brackets, and structural connections where high-strength inch-series fasteners are required. The fully threaded body provides maximum thread engagement across the full shank length, making it well-suited for shorter clamping distances or applications requiring a nut to be run the full length of the bolt. The smooth flange face is appropriate where surface contact must remain flush and clean.

Key Features

• 5/16-18 UNC thread form for standard inch-series compatibility
• Fully threaded shank with 1.5-inch length under head for maximum thread engagement
• 11/16-inch smooth flange diameter distributes load without a separate washer
• Grade 8 alloy steel construction for high tensile and proof load ratings
• Phosphate and oil finish provides corrosion and wear resistance
• Conforms to SAE J429 fastener standard

Compatibility

Designed as a standard 5/16-18 UNC inch-series smooth flange bolt for use in any application requiring SAE J429 Grade 8 hardware with a hex drive and integral flange bearing surface.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or licensed tradespeople using a standard hex wrench or socket. Ensure mating threads are clean and free of debris before assembly. Follow equipment manufacturer torque specifications for Grade 8 fasteners of this thread size. Do not mix Grade 8 hardware with lower-grade nuts or threaded inserts, as mismatched grades can compromise joint integrity.
