Ok, cheers. So just to clarify, adding more washers between the nut and the surface gives no advantage in terms of allowable tension applied to the nut or ease of releasing the nut again?
Thanks. But does that mean that a single washer should always be enough or is there an advantage to having two or more (besides in cases where extra washers are used to distribute the load)?
Is there an optimum number of washers to be used on a threaded bolt in respect to dissipation of energy towards the nut? And how would one calculate the dissipation rate of each washer?
