Roll bar connection

You'll have tension in the bolt as long as it is stretched. If the bolts are stretched in the same (parallel)direction. there should be no change in clamp force regardless of which end the head is pointing.



The fact the ballistic does it does not answer my question, why do they do it? How does it 'increase the strength substantially'? I am a mechanical engineer, and while doing seat pull testing early in my career, did some study on threaded fasteners. I don't recall anything that supports SDS's claim. I'm not saying he's wrong, I'm saying explain it to me so it makes sense.
