Our Mopar hex flange head bolts (06510140AA) are fastening accessories that secure the exhaust manifold, keeping it in place even under extreme pressure.

These fasteners have a large bearing surface for even clamping force distribution and a gap of 1.25mm between each thread. The gaps make sure the bolts provide a strong grip on the mating surface to resist any sort of loosening.

While most hex flange bolts are used on truck frames or anything that requires such type of fastening, this particular bolt is connected to the exhaust manifold. Since your manifold is constantly exposed to high temperatures during the combustion process, the hex flange bolts will continuously expand and contract, causing it to loosen or break over time. As a result, this could further cause leaking in your exhaust manifold that might affect your vehicle’s combustion.
