Review on 🔩 Dewhel 10-piece stainless steel exhaust manifold stud kit for Super Duty Ford 6.8 Liter V10 (One Side) manifolds by Michael Ward

I am a maintenance manager at a company that maintains state buses and I manage 5 shops. I started using them as they were cheaper than the direct from Ford. And I liked that they are all polished stainless steel. We made about 20 exhaust manifolds and found that the nuts would loosen after a while. Now the first thing I realized was that the mechanic just messed up, but the problem happened in multiple places and with multiple mechanics, so there's a bug here. A very easy way for a seller or supplier to fix this is to make the nuts self-locking nuts. I'm sure it will take about a millionth of a second for the nuts to essentially deform for a brief moment and this ensures that the nuts don't come loose when we don't want them to. Now I think I need to try something different for a while
