What is the primary purpose of a torque wrench?
Answer: To apply a specific amount of rotational force to a fastener
A torque wrench is a precision tool that allows the user to apply a specific, measured amount of torque (rotational force) to a fastener, ensuring it is neither too loose nor overtightened, which is critical in engines and structural assemblies.
Which type of saw is best suited for cutting curves and irregular shapes in wood?
Answer: Jigsaw
A jigsaw has a narrow, reciprocating blade that can pivot and follow curved or irregular cutting lines, making it the ideal choice when straight cuts are not required.
What is a utility knife most commonly used for in mechanical and construction work?
Answer: Scoring or cutting soft materials like drywall, cardboard, and plastic sheeting
A utility knife features a retractable, replaceable blade designed for scoring and cutting soft or thin materials such as drywall, cardboard, rope, and plastic sheeting — not hard materials like metal or thick wood.
What does a tap and die set allow a mechanic to do?
Answer: Cut or repair threads on bolts and in holes
A tap cuts internal threads inside a hole (so a bolt can screw in), while a die cuts external threads onto a rod or bolt. Together they allow mechanics to create new threads or restore damaged ones.
Which hand tool is used to measure and mark a straight line at a precise right angle (90°) to an edge?
Answer: Combination square
A combination square has a ruler and a sliding head fixed at 90° (and often 45°), allowing the user to scribe accurate right-angle lines from any edge — essential for layout work in carpentry and metalworking.
What is the function of a punch (center punch) in metalworking?
Answer: To create a small indentation that guides a drill bit and prevents it from wandering
A center punch is struck with a hammer to make a small dimple on a metal surface at the exact spot where a hole is to be drilled. This indentation keeps the drill bit from sliding sideways when drilling begins.
