The pipe wrench, or Stillson wrench is an adjustable wrench used for turning soft iron pipes and fittings with a rounded surface. The design of the adjustable jaw allows it to rock in the frame, such that any forward pressure on the handle tends to pull the jaws tighter together. Teeth angled in the direction of turn dig into the soft pipe. They are not intended for use on hard hex nuts because they would ruin the head; however, when a hex nut becomes rounded beyond use with standard wrenches, the pipe wrench is sometimes used to break the bolt or nut free. Pipe wrenches are usually sold in the following sizes (by length of handle): 10, 14, 18, 24, 36, and 48 inches, although smaller and larger sizes are available as well. They are usually made of either steel or aluminium. Teeth, and jaw kits (which also contain adjustment rings and springs) can be bought to repair broken wrenches, as this is cheaper than buying a new wrench.
In countries such as Australia and the United Kingdom, the previously common term "Stillson's" or "set of Stillson's" is being progressively replaced in everyday speech by the colloquial term monkey wrenches. This usage is not technically correct, as the term "monkey wrench" refers to a now uncommon type of adjustable wrench that was designed for use with nuts rather than with round pipes.
In South Africa, the terms "bobbejaan spanner" and "baboon spanner" are commonly used, especially for large pipe wrenches. "Bobbejaan" is the Afrikaans term for a baboon.
