Value Collection 824228MSC Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 824228MSC is a fully threaded serrated flange bolt designed for high-strength fastening in structural and mechanical assemblies. It features a 3/8-16 UNC thread size with a 2-inch length under head, and a serrated flange diameter of 0.81 inches that bites into the mating surface to resist loosening under vibration. The bolt is manufactured from Grade 8 steel and finished with a zinc plating for corrosion resistance. This fastener meets ASME B18.6.3 and SAE J429 standards, making it appropriate for applications where both strength and dimensional compliance are required. Installation is performed with a standard hex drive tool.

This bolt is suited for use in industrial, mechanical, and structural applications where a high-strength, vibration-resistant fastener is needed. The serrated flange eliminates the need for a separate lock washer by providing built-in resistance to loosening. Common install scenarios include equipment mounting, machinery assembly, and structural connections in manufacturing and maintenance environments. The fully threaded design offers maximum thread engagement across the full 2-inch length under head.

Key Features

• 3/8-16 UNC thread size with 2-inch fully threaded length under head
• Serrated flange diameter of 0.81 inches provides integrated vibration resistance without a separate lock washer
• Grade 8 steel construction for high tensile and proof load strength
• Zinc-plated finish for corrosion protection in general-use environments
• Hex drive for installation with standard wrenches or sockets
• Meets ASME B18.6.3 and SAE J429 standards

Compatibility

Designed as a standard inch-series serrated flange bolt compatible with 3/8-16 UNC tapped holes and standard hex-drive tooling in industrial and mechanical assembly applications.

Installation Notes

Serrated flange bolts are typically installed by maintenance technicians and mechanical assemblers using standard hex wrenches or impact drivers. Ensure the mating surface is clean and flat so the serrated flange can seat properly and engage its locking function. Do not install these bolts into materials too soft to withstand the serration contact force, as this may damage the mating surface and reduce clamp load. Follow applicable torque guidelines from engineering specifications for Grade 8 fasteners in the relevant application.
