Which tool is used to cut external threads on a metal rod or bolt?
Answer: Die
A die is the tool used to cut external threads onto a rod or bolt. A tap is its counterpart, used to cut internal threads inside a hole.
What is the primary function of a cold chisel?
Answer: Cutting or shaping unhardened metal
A cold chisel is a hardened steel tool used to cut, shear, or chip unhardened metal when struck with a hammer. It is called 'cold' because it cuts metal that has not been heated.
Which measuring tool uses a calibrated screw mechanism to measure small dimensions to within 0.001 inch?
Answer: Micrometer
A micrometer uses a precisely machined screw thread to achieve very fine measurements, typically to 0.001 inch or better. Vernier calipers are accurate but generally less precise than a micrometer.
A C-clamp is most commonly used in a workshop to:
Answer: Hold workpieces together while adhesive dries or during welding
C-clamps provide strong clamping force to hold workpieces firmly together or against a surface, making them essential when gluing, welding, or machining parts that must remain stationary.
Which type of screwdriver bit is designed to reduce cam-out by engaging more contact points on the fastener head?
Answer: Pozidriv
Pozidriv has additional radial ribs between the four main arms, giving more contact points and reducing the tendency to slip out (cam-out) under high torque compared to a standard Phillips head.
What is the correct tool to use when you need to remove a roll pin from a drilled hole in a shaft?
Answer: Pin punch and hammer
A pin punch has a flat, straight tip the same diameter as the pin, allowing it to follow the pin all the way through and out of the hole without damaging the surrounding material.
