Halfords Adjustable Wrench 256362

Chain store giant’s wrench opens to the same 21mm as the Irega, but has a lot more play in the jaw, which rattles around. The handle isn’t very comfortable, either, although there’s lots of leverage and we undid all the nuts in our vice. As with our winner, the coloured handle helps you find it in the tool box, but the Halfords is more expensive.
