🔍 Key Concepts

• Open-end wrench design – shape of the jaws and how they contact fasteners • Difference between adjustable and nonadjustable wrenches • Common uses of tools designed to grip round objects vs tools for nuts and bolts

💭 Think About

• Think about what shape fastener an open-end wrench is made to fit around. Is it round, square, or hex (six-sided)? • Consider whether you change the size of an open-end wrench each time you use it, or if each wrench is made for a specific size. • Which type of wrench would be more likely used with a separate handle or driver, like a speeder handle?

✅ Before You Answer

• Confirm whether an open-end wrench has fixed-size openings or an adjustable jaw. • Check if tools for round objects (like pipe wrenches or slip-joint pliers) look and work the same as an open-end wrench. • Verify which wrench types are commonly used with speeder handles (think about sockets vs. fixed wrenches).
