on heavy industrial jobs, you would be severley moaned at for using 5 holes/grips to tighten glands. its either adjustables, or spanners. i use these: Google Image Result for http://cdn1.shopperhive.co.uk/n/bahco-6-ergo-wide-jaw-adjustable-wrench.jpg.
they will do upto 25mm glands. on small jobs, where the firm dont have dedicated glanding spanners, i use these to do bigger glands: CHANNELLOCK Straight Jaw.
ive just seen that they do a smooth jaw version, while trying to find a link to put here. the ones above cost ÂŁ25 a set, but that is cheap i think.
i may well invest in a smooth jaw set!
