The main difference between a common lathe dog and a safety lathe dog is that the latter _______________.

AI Explanation
The correct answer is B) has a headless set screw. The key difference between a common lathe dog and a safety lathe dog is that the safety lathe dog has a headless set screw, which helps prevent the workpiece from being accidentally dislodged during operation. The headless design reduces the risk of the set screw catching on the operator's clothing or skin, making it a safer option for use in a lathe. The other answer choices do not accurately describe the primary distinction between these two types of lathe dogs.
