Engine front mounting bolts

[Peter Stanley]

Using a bolt instead of a stud would be easier. I think the engine mounting stud has the advantage of the integral flange (nut shaped). When the stud is tightened up in the normal way, the flange sits tight up onto the chassis and helps to provide a very firm mount. I believe this would help to ensure that there is no lateral movement due to the engine trying to move backwards and forwards. If movement occurs the the hole/thread in the chassis could be damaged.

I think this is why the engine mount with integral flange is used.
