Q

A pipe or Stillson wrench should only be used on __________.

🔍 Key Concepts

• Pipe/Stillson wrench jaw shape and teeth • How different object shapes (round, hex, square, flat) contact the wrench jaws • Why some tools are designed for nuts/bolts and others for pipes

💭 Think About

• Think about which shape allows the wrench’s serrated jaws to bite and grip securely as you apply turning force. • Consider which shapes are usually turned with open-end or box-end wrenches instead of a pipe/Stillson wrench. • Ask yourself: what kind of material and shape is a pipe/Stillson wrench normally used on in plumbing or engine-room work?

✅ Before You Answer

• Identify which object shapes are commonly turned by adjustable wrenches or box-end wrenches, not pipe wrenches. • Visualize the contact area between the wrench jaws and each shape—where will the teeth dig in and hold best? • Remember that a pipe/Stillson wrench is typically used on piping and similar fittings, not finished nut heads.
