Frequently Asked Questions (FAQs)

1. What is the difference between a spud wrench and a pipe wrench?

Both spud wrench and pipe wrench are for pipes, yet they differ in pipe usage because a spud wrench is mostly preferred in automotive pipe work as an alternative to the adjustable wrench, with lining up bolt holes when installing pipe fittings, while the pipe wrench is used in plumbing.

2. What should you not use a pipe wrench for?

Never use a pipe wrench to bend, raise or lift a pipe. Adjust the pipe wrench grip to maintain a gap between the back of the hook jaw and the pipe. This concentrates the pressure at the jaw teeth, producing the maximum gripping force. It also aids the ratcheting action.

3. Why do plumbers use pipe wrenches?

A pipe wrench is any of several types of wrench that are designed to turn threaded pipe and pipe fittings for assembly (tightening) or disassembly (loosening). The Stillson wrench, or Stillson-pattern wrench, is the usual form of pipe wrench, especially in North America.

4. What is the difference between a pipe wrench and a monkey wrench?

Monkey wrenches and pipe wrenches are very similar, but they have different jaw designs. Monkey wrenches have flat jaws, while the jaws on pipe wrenches have teeth for gripping rounded surfaces. You should use monkey wrenches for flat surfaces and pipe wrenches for rounded surfaces.
