Value Collection C39060 Flange Bolt 1/2-20 Unf Grade 8

Product Description

The VALUE COLLECTION C39060 is a smooth flange bolt designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Threaded to the 1/2-20 UNF standard with a 1-1/2 inch length under head and fully threaded shank, this bolt delivers consistent clamping force across the full bearing surface. The integral smooth flange — measuring 1-5/64 inches (1.0781 inches) in diameter — distributes load evenly without requiring a separate washer. Manufactured from Grade 8 alloy steel and left uncoated, it meets IFI 111 and SAE J429 standards. Tradespeople, maintenance technicians, and assembly mechanics rely on this fastener where rated tensile strength and dimensional accuracy are non-negotiable.

This flange bolt is suited for general mechanical assemblies, automotive and heavy-equipment repair, and industrial maintenance applications where a fine-thread, high-strength fastener is required. The 1/2-20 UNF thread pitch provides superior thread engagement and vibration resistance compared to coarse-thread equivalents, making it a common choice in drivetrain, suspension, and precision-fit mechanical joints. It is sold as a single piece with a minimum order quantity of 25 units.

Key Features

• 1/2-20 UNF fine thread for superior engagement and vibration resistance
• Fully threaded shank — 1-1/2 inch length under head
• Integral smooth flange (1-5/64 inches diameter) distributes clamp load without a separate washer
• Grade 8 alloy steel construction for high tensile and proof-load strength
• Uncoated finish — suitable for applications where coating is specified separately or not required
• Meets IFI 111 and SAE J429 fastener standards

Compatibility

Designed as a standard UNF smooth flange bolt for use in any application requiring a 1/2-20 fine-thread, Grade 8 fastener with an integral flanged bearing surface.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using a standard hex-drive tool sized for a 1/2-20 bolt head. Verify thread engagement depth and joint design before torquing; consult applicable engineering standards for torque specifications based on Grade 8 fastener requirements and joint material. Do not mix inch and metric fasteners in the same assembly. Inspect threads for damage before installation and replace any fastener showing deformation or corrosion.
