ACDelco Heavy Hex Flange Bolt

The ACDelco Heavy Hex Flange Bolt line provides OE-style replacement fasteners for secure, dependable assembly and repair work. Each bolt has a heavy hex head with an integral flange. The flange spreads clamping load over a wider surface, so a separate washer isn't needed. These flanged hex bolts are also sold as flange head bolts or hex flange screws. They suit engine, transmission, chassis, and general service applications.

Key Features:

• Heavy hex head with an integral flange for even load distribution and a secure seating surface
• Steel construction, with protective plating or finishes used across the line
• Engineered, tested, and validated to meet fit, form, and function expectations
• Backed by ACDelco, a brand with more than 100 years of automotive experience
• Designed as direct replacements for the original fasteners

Replacing worn, damaged, or corroded fasteners with quality hardware helps keep assemblies tight and reliable. Choose the matching child part number for your application.
