🔍 Key Concepts

• Proper tool-to-fastener matching (using the right screwdriver tip for the right screw slot) • How cam-out and slipping can damage parts • Difference between damage to the tool vs damage to the screwhead

💭 Think About

• When the wrong screwdriver type is used on a screw, what physically happens between the tip and the screw slots? • Which part experiences wear or rounding first when the driver slips: the metal of the screwhead, the metal of the tool, or both? • If the screwdriver tip deforms, how will that affect future use on correct screws? If the screwhead deforms, what problems does that create?

✅ Before You Answer

• Think about whether only the screwhead, only the tool, both, or neither can be damaged during repeated slipping • Visualize how a worn screwdriver tip behaves in a screw head—does it increase or decrease the chance of further damage? • Be sure you can explain, in your own words, why protecting the screwhead is important and why preserving the tool also matters.
