plumber wrench

It was during the years in his workshop that he invented the adjustable spanner and the plumber wrench.

A plumber wrench is a pipe wrench used to rotate pipes used in plumbing.

The fasteners securing faucets and other connections under a sink are often in very tight places which would make access with a plumber wrench or other tools impossible.

The plumber wrench was invented in the year 1888 by Swedish inventor Johan Petter Johansson, who also held an 1891 patent on an improved version of the adjustable spanner.

Hinged tools, such as pliers or tongs, are not generally considered wrenches in English, but exceptions are the plumber wrench (pipe wrench in British English) and mole wrench (mole grips in British English).
