🔍 Key Concepts

• Function of a shaft collar lock screw (what it must do to the shaft to prevent slipping) • Difference between set screws (often headless, with special points) and ordinary machine screws • Importance of the point shape and head style for transmitting holding force to a rotating shaft

💭 Think About

• Look at figures F, G, H, and L and compare the tips of the screws: which ones are shaped to bite into a shaft, and which are more likely to just press without much grip? • Consider how the head style affects the installation in a shaft collar: which designs can sit entirely within the collar, and which will stick out or not fit a typical threaded collar hole? • Ask yourself which figure would give the least positive locking action against rotation if the shaft tried to turn inside the collar.

✅ Before You Answer

• Identify which figures look like true set screws (often short, with no projecting head) versus regular machine/bolt heads. • Check which screw point is flat versus cone or cup-shaped and think about how that affects the ability to bite into the shaft surface. • Make sure the option you pick would be the worst choice for preventing shaft movement, not just the least convenient to install.
