ASVAB Shop Information 3 — Questions and Answers
Question 1: What is the primary function of a torque wrench?
- To apply maximum force to loosen rusted bolts
- To tighten fasteners to a specific rotational force (Correct answer)
- To measure bolt thread pitch
- To hold nuts stationary while tightening bolts
Correct answer: To tighten fasteners to a specific rotational force
A torque wrench applies and measures a precise amount of rotational force (torque) to prevent over- or under-tightening fasteners.
Question 2: In plumbing, what type of joint uses heat to fuse copper pipe and fittings together?
- Compression joint
- Threaded joint
- Sweat (solder) joint (Correct answer)
- Push-fit joint
Correct answer: Sweat (solder) joint
A sweat joint uses a torch to heat copper pipe and a fitting, then solder is drawn in by capillary action to create a watertight seal.
Question 3: What does 'RPM' stand for in the context of power tools?
- Rotational Power Measurement
- Revolutions Per Minute (Correct answer)
- Rated Power Mode
- Resistance Per Motor
Correct answer: Revolutions Per Minute
RPM stands for Revolutions Per Minute, indicating how fast a motor shaft or blade spins.
Question 4: Which type of paint finish is most durable and easiest to clean, making it ideal for trim and doors?
- Flat/matte
- Eggshell
- Satin
- Semi-gloss or gloss (Correct answer)
Correct answer: Semi-gloss or gloss
Semi-gloss and gloss finishes are the hardest, most moisture-resistant, and easiest to wipe clean, ideal for high-contact surfaces.
Question 5: What is the purpose of flux when soldering copper pipe?
- To strengthen the solder joint after cooling
- To clean oxides and help solder flow into the joint (Correct answer)
- To increase the melting point of the solder
- To seal any gaps the solder misses
Correct answer: To clean oxides and help solder flow into the joint
Flux chemically cleans metal surfaces and prevents re-oxidation during heating, allowing molten solder to wet and flow evenly.
Question 6: A pilot hole is drilled before driving a screw primarily to:
- Make the screw easier to remove later
- Prevent the wood from splitting and guide the screw straight (Correct answer)
- Increase the holding strength of the screw
- Allow countersinking of the screw head
Correct answer: Prevent the wood from splitting and guide the screw straight
A pilot hole creates a guide channel that prevents wood splitting, especially near edges, and helps the screw drive straight.
Question 7: Which type of bolt has threads running its entire length from head to tip?
- Carriage bolt
- Cap screw
- Stud bolt
- Fully threaded bolt (Correct answer)
Correct answer: Fully threaded bolt
A fully threaded bolt has threads covering its entire shank length, as opposed to partially threaded bolts with a smooth grip section.
