Which tool is used to measure the inside diameter of a pipe or bore?
Answer: Inside calipers
Inside calipers are specifically designed to measure internal dimensions such as the inside diameter of pipes and bores.
A torque wrench is used primarily to:
Answer: Apply a specific tightening force to a fastener
A torque wrench applies a precise, measurable rotational force (torque) to a fastener to prevent over- or under-tightening.
What is the purpose of a tap and die set?
Answer: Creating or restoring internal and external threads
A tap cuts internal threads (in holes) while a die cuts external threads (on rods or bolts).
Which punch type is used to mark a center point before drilling?
Answer: Center punch
A center punch creates a small indentation that guides the drill bit and prevents it from walking on the surface.
A hacksaw blade with more teeth per inch (TPI) is best suited for cutting:
Answer: Thin-walled tubing and sheet metal
Higher TPI blades produce finer cuts and are required for thin materials to keep at least two teeth in contact with the workpiece.
What tool would you use to check whether a surface is perfectly level?
Answer: Spirit level
A spirit level uses a bubble in liquid-filled vials to indicate whether a surface is horizontal (level) or vertical (plumb).
A pipe wrench differs from a standard adjustable wrench because it:
Answer: Uses serrated jaws that grip round objects
Pipe wrenches have hardened, angled serrated teeth designed to bite into and grip cylindrical surfaces like pipes.
