Question 1

Which tool is used to cut external threads on a metal rod or bolt?

Die

Answer

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.

Cutting or shaping unhardened metal

Answer

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.

Question 3

Which measuring tool uses a calibrated screw mechanism to measure small dimensions to within 0.001 inch?

Accepted Answer

Micrometer

Answer

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.

Question 4

A C-clamp is most commonly used in a workshop to:

Accepted Answer

Hold workpieces together while adhesive dries or during welding

Answer

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.

Question 5

Which type of screwdriver bit is designed to reduce cam-out by engaging more contact points on the fastener head?

Accepted Answer

Pozidriv

Answer

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.
