NTN FIRETEAM EXAM PREDICTIVE EXAM SET
2026-2027 | 200 QUESTIONS WITH CORRECT ANSWERS &
RATIONALES
1. What do you use to tighten a bolt?
A) Pliers
B) Socket wrench
C) Adjustable wrench
D) Torque wrench
Correct Answer: B) Socket wrench
Rationale: A socket wrench is specifically designed to turn bolts with a
socket that fits snugly onto the bolt head, allowing for efficient and
precise tightening. This design enables the user to apply necessary
torque without damaging surrounding material or stripping the bolt's
threads.
2. What shape is a drill bit used for metal?
A) Pointed tip with protruding edges
B) Squared off tip
C) Sleek shape, not pointed, no protruding edges
D) Threaded point with spiral flutes
Correct Answer: C) Sleek shape, not pointed, no protruding edges
,Rationale: A drill bit for metal requires a sleek shape to reduce friction
and prevent overheating, which can damage the metal or cause the bit
to break. The absence of pointed or protruding edges ensures smooth
insertion and consistent, controlled drilling.
3. What shape drill bit is hand operated for drilling wood?
A) Sleek shape with no protruding edges
B) Squared off tip bit
C) Tip is a threaded point with protruding edges
D) Diamond tip bit
Correct Answer: C) Tip is a threaded point with protruding edges
Rationale: This refers to the Brad point drill bit, specifically designed to
drill straight holes in wood without splitting. The threaded point and
protruding edges create a pilot hole that guides the drill and prevents
the wood from splitting.
4. What shape drill bit is used for ceramics/masonry?
A) Threaded point bit
B) Sleek shape bit
C) Squared off tip bit
D) Diamond-coated bit
Correct Answer: C) Squared off tip bit
Rationale: A squared-off tip bit provides a controlled entry point and
minimizes the risk of the bit walking or slipping when drilling through
,hard, brittle materials like ceramics and masonry. This design reduces
the likelihood of material cracking or shattering.
5. Small gear vs big gear, what turns faster?
A) Small gear
B) Big gear
C) Both turn at the same speed
D) Neither gear turns
Correct Answer: A) Small gear
Rationale: In a gear system, the smaller gear rotates faster than the
larger gear when meshed together. This is because the smaller gear has
fewer teeth and must complete more revolutions to keep up with the
larger gear's tooth engagement.
6. When installing a bolt with washer and nut, what side faces you?
A) Washer side faces you
B) Nut side faces you
C) Threaded end goes away from body to prevent hazard
D) Bolt head faces you
Correct Answer: C) Threaded end goes away from body to prevent
hazard
Rationale: The threaded end should face away from the body to prevent
injury from protruding threads. This safety practice ensures that sharp
threads do not catch on clothing or skin during installation.
, 7. What tool is used to cut bolts?
A) Bolt cutters
B) Hacksaw
C) Angle grinder
D) Tin snips
Correct Answer: B) Hacksaw
Rationale: A hacksaw is the correct tool for cutting bolts. Bolt cutters
are designed for cutting softer materials like chain links and wire, not
hardened steel bolts. A hacksaw provides clean, precise cuts on metal
bolts.
8. Mechanical Brick Factory: What do you do if there is unmelted
material?
A) Increase the temperature
B) Stop and call mechanic
C) Add more material
D) Increase belt speed
Correct Answer: B) Stop and call mechanic
Rationale: Unmelted material indicates a malfunction in the melting
process. Continuing operation could cause damage or create a safety
hazard. The proper response is to stop the machine and call a qualified
mechanic for diagnosis and repair.
9. Mechanical Brick Factory: If you want more material from the start
of the assembly, what do you do?
