Value Collection 822837MSC Smooth Flange Bolt 5/16-18 Unc

Product Description

The VALUE COLLECTION 822837MSC is a smooth flange bolt designed for structural fastening applications requiring a broad bearing surface and a clean, non-serrated flange face. It features a 5/16-18 UNC thread profile and measures 2-1/4 inches in length under the head with a partial thread length of 7/8 inches. The flange diameter is 11/16 inches (0.6875 inches). Manufactured from Grade 8 alloy steel with a phosphate and oil finish, this bolt meets SAE J429 standards, making it suited for high-strength bolted joint assemblies. It is driven with a standard hex tool and is sold individually.

This flange bolt is used in mechanical, industrial, and light-structural assemblies where a built-in washer flange helps distribute clamp load across the mating surface. The smooth flange face is appropriate for applications where a non-marring, non-locking flange contact is required. Grade 8 alloy steel construction supports high tensile and proof load demands, common in equipment mounting, bracket fastening, and machine assembly work performed by millwrights, maintenance technicians, and mechanical contractors.

Key Features

• 5/16-18 UNC thread form with 7/8-inch partial thread length
• Grade 8 alloy steel for high tensile strength per SAE J429
• Smooth flange face distributes clamp load without marring the mating surface
• 11/16-inch flange diameter (0.6875 inches) provides broad bearing area
• Phosphate and oil finish offers moderate corrosion and wear resistance
• Hex drive compatible with standard wrenches and sockets

Compatibility

Designed as an OEM-style replacement or new-installation fastener for any application requiring a 5/16-18 UNC smooth flange bolt with Grade 8 strength rating and SAE J429 compliance.

Installation Notes

Installation is performed by qualified mechanical technicians or tradespeople using standard hex wrenches or socket drivers. Ensure mating threads are clean and free of debris before installation. Do not exceed torque values specified by the equipment manufacturer or applicable engineering standards for Grade 8 fasteners. Phosphate and oil finish is not intended as a long-term outdoor corrosion barrier; consult application requirements before use in exposed environments.
