plumbers wrench

Its a metal tool used by engineers, mechanics fitters plumbers etc that has a shaped end, used to turn nuts and bolts. These are normally fixed tools meaning a spanner will have two shaped ends of slightly differing size to accomadate two different nuts or bolts. The open end(s) come a vast array of wides to fit many differing nut/bolt sizes. Adjustable spanners are also available whose opening is controlled by a screw and can be turned to fit most standard nust/bolts however, these are not as strong as the fixed jaw type
