Q

In machine shop practice, a center gauge is used for checking the angle of __________.

🔍 Key Concepts

• What a center gauge looks like and how it is used near a lathe or thread-cutting setup • Difference between thread pitch (distance between threads) and thread angle (included angle of the V-shape of the thread) • Typical angle of standard V-threads used in machine shop practice (think 60°)

💭 Think About

• Ask yourself: Is a center gauge normally placed against the tool, or directly against the finished thread or drill point? • Which option mentions an angle that is a specific, fixed value commonly associated with standard V-threads? • Among the choices, which item actually involves a 60° included angle as a design feature rather than just spacing or distance between features?

✅ Before You Answer

• Be clear on the difference between pitch (spacing) and angle (shape of the V) when dealing with screw threads • Visualize how a machinist sets up a lathe tool before cutting threads—what tool do they use to check that tool’s angle? • Confirm which items in the choices are primarily checked with thread pitch gauges versus a tool specifically called a center gauge
