🔍 Key Concepts

• Common types of screwdriver shafts and how they are constructed • What purpose a flexible or coiled shaft would serve when working in tight or angled spaces

💭 Think About

• Which screwdriver type in the list sounds like it would need to bend or curve during use? • Which type name refers to size or shape of the handle/shaft, and which refers to a special internal mechanism rather than shaft construction?

✅ Before You Answer

• Match the phrase "double coil wire or tightly coiled steel" with the only option that suggests bending or flexibility • Separate options that describe shape/size (square, jeweler's) from those that describe function/mechanism (flex, ratchet) • Ask yourself: which of these would actually be built from coiled material instead of a solid metal bar?
