Value Collection C39035 Flange Bolt 1/2-13 Unc 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION C39035 is a smooth flange bolt designed for high-strength fastening applications requiring a wide bearing surface without a separate washer. Sized at 1/2-13 UNC with a 1-1/2 inch length under head and fully threaded shank, this bolt delivers reliable clamping force in structural and mechanical assemblies. The integrated smooth flange measures 1-5/64 inches (1.0781 inches decimal) in diameter, distributing load evenly across the mating surface. Manufactured from Grade 8 alloy steel and left uncoated, it meets IFI 111 and SAE J429 standards. Machinists, millwrights, and maintenance technicians commonly install these in equipment, fixtures, and structural connections.

This flange bolt is suited for general industrial and mechanical fastening where a hex-drive, fully threaded bolt with an integrated flange is required. The UNC thread form makes it compatible with standard inch-series tapped holes and nuts. It is appropriate for use in fabrication shops, manufacturing equipment, maintenance and repair operations, and similar trade applications where Grade 8 tensile strength is specified.

Key Features

• 1/2-13 UNC fully threaded shank for use with standard inch-series hardware
• 1-1/2 inch length under head with smooth integrated flange eliminates the need for a separate flat washer
• 1-5/64 inch (1.0781 inches) flange diameter provides broad load distribution
• Grade 8 alloy steel construction for high tensile strength in demanding applications
• Hex drive for use with standard wrenches and sockets
• Meets IFI 111 and SAE J429 fastener standards

Compatibility

Designed as an OEM-style replacement or standard fitment for applications requiring a 1/2-13 UNC smooth flange bolt with Grade 8 alloy steel construction and IFI 111 and SAE J429 compliance.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using standard hex wrenches or sockets sized for 1/2-inch bolt heads. Ensure the mating tapped hole or nut matches the 1/2-13 UNC thread specification before installation. De-energize and lock out any equipment before fastener service. Do not exceed the torque range appropriate for Grade 8 hardware at this thread size as defined by your applicable engineering or facility standards.
