ASVAB Shop Information Test 4 — Questions and Answers
Question 1: Which type of screwdriver bit is designed for a screw with two intersecting slots forming an 'X'?
- Flathead (slotted)
- Phillips (Correct answer)
- Torx
- Hex (Allen)
Correct answer: Phillips
A Phillips screwdriver has a cross-shaped tip that fits the X-shaped recess on Phillips-head screws.
Question 2: What is the main advantage of using a brad nailer over a hammer and finish nails by hand?
- It uses larger nails for stronger joints
- It reduces splitting and speeds up the work (Correct answer)
- It eliminates the need for wood glue
- It automatically countersinks nails below the surface
Correct answer: It reduces splitting and speeds up the work
A brad nailer drives thin nails quickly with less force, reducing wood splitting and increasing efficiency compared to hand nailing.
Question 3: What is the purpose of flux when soldering metal?
- To increase the melting point of the solder
- To clean the metal and prevent oxidation during heating (Correct answer)
- To strengthen the mechanical bond
- To color-code the joint for inspection
Correct answer: To clean the metal and prevent oxidation during heating
Flux chemically cleans metal surfaces and prevents oxidation while heat is applied, allowing solder to flow and bond properly.
Question 4: A dial caliper is used to measure:
- Angles and bevels
- Inside, outside, and depth dimensions with high precision (Correct answer)
- The hardness of metal
- Surface roughness
Correct answer: Inside, outside, and depth dimensions with high precision
A dial caliper can measure inside diameters, outside diameters, and depths with precision typically to 0.001 inch.
Question 5: What does a wire gauge number indicate?
- The voltage rating of the wire
- The diameter of the wire (higher number = thinner wire) (Correct answer)
- The insulation material used
- The maximum current in amps
Correct answer: The diameter of the wire (higher number = thinner wire)
Wire gauge (AWG) is an inverse measure of wire diameter — a higher AWG number means a thinner, smaller-diameter wire.
Question 6: Which type of joint is created when two boards are joined at their ends with interlocking rectangular notches?
- Dovetail joint
- Box (finger) joint (Correct answer)
- Butt joint
- Rabbet joint
Correct answer: Box (finger) joint
A box joint (also called a finger joint) uses interlocking rectangular notches cut at the ends of two boards to create a strong corner joint.
Question 7: What is a cold chisel primarily used for?
- Carving decorative patterns in wood
- Cutting or shaping metal without heat (Correct answer)
- Removing paint from brick surfaces
- Splitting wooden shingles
Correct answer: Cutting or shaping metal without heat
A cold chisel is a hardened steel tool struck with a hammer to cut, chip, or shape metal at room temperature without heat.
