🔍 Key Concepts

• Typical design and purpose of a set screw (how it is used on a shaft or hub) • How head shape and the need for a countersink or clearance affect the strength of the part the screw goes through • Which figures in the illustration are headless/fully threaded vs. those that have large heads or require a countersink

💭 Think About

• Look at how each of the four choices would sit in the hub of a gear or coupling that is locking onto a shaft. Which one would require you to remove the most metal from the hub or leave the least metal around the screw hole? • Which shape is most likely to be specified as an actual set screw style in machinery handbooks, and which looks more like an ordinary machine or cap screw used for clamping parts together? • Imagine the screw is tightened hard against a round shaft: which tip and head arrangement would give positive locking without weakening or damaging the hub excessively?

✅ Before You Answer

• Identify which choice is a true headless set screw and eliminate it from consideration first. • Compare which remaining options need a countersunk hole versus just a straight drilled/tapped hole through the hub. • Before picking an answer, be sure you’ve chosen the one that would be worst for locking a hub to a shaft while preserving hub strength.
