The Old Fat One: Many thanks for that information, but the witness only states that the indications were that the bolt was "Vastly over-tightened". We are assuming that that means more than one and a half threads showing. But surely someone must have checked the bolt after the accident. If only one and a half turns are showing, and the bolt vastly over tightened, there is something wrong with the instruction. It has already been stated by one witness that instructions were vague.
Has there been any evidence presented to the court by the person who fitted the nut and bolt? Were approved nuts and bolts used?
