I always do things up firmly with a sensible size spanner - Not too big.
Thanks but with-ought any thoughts of criticism and belittling etc. I prefer factual figures to be quote so can relate to known specifications.
I had done up the bolts "firmly" with a six inch 5/16 ring spanner - what I thought was tight enough. Then I set my torque wrench to a low reading and gradually increased the setting till the bolt just moved to see what the torque actually was (within the known inacuracy 0f +/- 25% attributed to torque wrench settings) and it turned out to be significantly lower than 18lbft. The bolts were new with copper slip applied to prevent any corrosion.
Mr weight lifter of the year would apply a very different "firm" pressure to that which my elderly wife would apply
