Value Collection 822842MSC Flange Bolt 3/8-16 Unc 3 in Grade 8

Product Description

The VALUE COLLECTION 822842MSC is a smooth flange bolt designed for secure fastening in mechanical and structural assemblies. It features a 3/8-16 UNC thread with a 3-inch length under the head and 1 inch of partial threading. The integral smooth flange distributes clamping load over a wider surface area, reducing the need for a separate washer. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it delivers high tensile strength and corrosion resistance suitable for demanding industrial and automotive applications. Installation is performed with a standard hex drive.

This bolt is used in automotive, heavy equipment, and general industrial assemblies where high-strength fasteners are required. The smooth flange bearing surface is well suited for applications involving softer base materials or where flange-style fasteners are specified by design. Partially threaded shanks allow for stronger grip in through-bolt configurations and reduce the risk of thread engagement at the shear plane. Licensed mechanics, millwrights, and maintenance technicians commonly install this fastener in chassis, bracket, and structural joint applications.

Key Features

• 3/8-16 UNC thread form with 1 inch of thread length
• 3-inch length under head for through-bolt and deep-clearance applications
• Smooth flange diameter of 13/16 inch (0.8125 inches) distributes clamping load without a separate washer
• Grade 8 alloy steel construction for high tensile and proof load strength
• Phosphate and oil finish provides baseline corrosion protection and lubricity during installation
• Meets SAE J429 fastener standard

Compatibility

Designed as a standard inch-series smooth flange bolt for use in any assembly specifying a 3/8-16 UNC Grade 8 partially threaded flange bolt with a 3-inch length under head.

Installation Notes

Install using a hex drive tool sized for the bolt head. Verify mating thread condition and ensure the flange bearing surface seats flat against the work piece before torquing. Follow the torque specifications published in your assembly drawing or applicable SAE or OEM fastener guidelines for Grade 8 hardware. Do not mix fastener grades within a joint, and replace any fastener that shows signs of thread damage or deformation.
