Hex keys are commonly referred to as allen keys, named after their inventor, the Allen Manufacturing Company. The other options, ball-tip keys, fold-out keys, and T-keys, may refer to specific types of hex keys with different features or designs.

Question 8

The adjustable wrench __________ intended to be used to loosen extremely tight nuts and bolts or to provide final tightening of nuts and bolts.
A) is
B) is not

Accepted Answer

The use of an adjustable wrench for loosening extremely tight nuts and bolts can damage the tool and lead to rounded or stripped bolt heads. It is best to use a specialized tool such as a breaker bar or torque wrench for these applications.

Question 9

Typically, corded drills supply __________ power than the cordless variety.
A) less
B) more

Accepted Answer

Corded drills typically supply more power than cordless drills because they are connected directly to a power source, allowing for continuous high power output without the limitations of battery capacity.

Question 10

Longer shanks provide more __________ , so the technician should be sure to use a screwdriver with a longer handle if more twisting force is required.
A) cheek
B) precision
C) speed
D) torque

Accepted Answer

Longer shanks provide more torque, which is the twisting force applied to a rotating object. Therefore, using a screwdriver with a longer handle would be necessary to provide more twisting force.

Question 11

Hex keys are commonly used to secure or remove blowers from _________.
A) conductors
B) ducts
C) motor shafts
D) pipes

Accepted Answer

Hex keys, also known as Allen keys, are commonly used to secure or remove blowers from motor shafts. They fit into a hexagonal socket in a bolt or screw head, which are often found in the assembly of motor-driven equipment like blowers.

Question 12

When working in spaces with low clearance, __________ screwdrivers, which are screwdrivers with very short shanks, are often needed
A) hex-head
B) long-handled
C) offset
D) stubby-type

Accepted Answer

Stubby-type screwdrivers have very short shanks and are designed for use in tight spaces with low clearance. Hex-head screwdrivers have a specific shape for use with hex screws, but they do not necessarily have a shorter shank. Long-handled screwdrivers have longer shafts for reaching screws in deep or hard-to-reach spaces but are not ideal for low clearance areas. Offset screwdrivers have angled shafts that allow for access around obstacles but do not necessarily have a shorter shank.

Question 13

Wire strippers are designed for which of the following tasks?
A) crimping solderless connectors onto sections of stripped stranded wire
B) cutting small screws or bolts
C) cutting wire
D) all of the above

Accepted Answer

Wire strippers are versatile tools designed for multiple tasks including crimping solderless connectors, cutting small screws or bolts, and cutting wire.

Question 14

Generally speaking, chisels are tools that are struck with hammers in order to __________ materials.
A) conjoin
B) modify
C) remove or cut
D) reshape

Accepted Answer

Chisels have a sharp edge that is used to remove or cut materials such as wood, stone, or metal. They are often struck with a hammer to provide force and precision to the cutting action.

Question 15

Open-end wrenches are often manufactured with a __________ offset angle so the user can easily turn a hex head bolt or screw completely by flipping the wrench over.
A) 15 °
B) 30 °
C) 50 °
D) 65 °

Accepted Answer

Open-end wrenches are typically manufactured with a 15° offset angle. This design feature allows the user to flip the wrench over after a partial turn, enabling them to engage the fastener from a different angle and continue turning it without having to remove the wrench completely. This makes the process of tightening or loosening hex head bolts or screws more efficient.

Question 16

The hacksaw __________ recommended for cutting piping material that is used in a refrigerant-carrying piping circuit.
A) is
B) is not

Accepted Answer

A hacksaw is not recommended for cutting piping material used in a refrigerant-carrying piping circuit because it can leave metal shavings inside the pipe, which can contaminate the refrigerant and cause system failure. A tubing cutter or a reciprocating saw with a metal-cutting blade is a better choice for this application.
