Review:Pliers, Wrenches,Sockets And Ratchets, Measuring Tools, Levels, Plumb Bob

The electronic version of a tape measure is a laser measuring tool. This tool uses laser technology to accurately measure distances. It is more precise and efficient compared to traditional tape measures. By emitting a laser beam, it can quickly calculate the distance between two points. The laser measuring tool is commonly used in construction, interior design, and other industries where precise measurements are required.

A combination wrench is the correct answer because it has both an open-end wrench and a box-end wrench. This means that it can be used for different types of fasteners, providing versatility and convenience for the user. The open-end wrench is typically used for nuts and bolts with a flat surface, while the box-end wrench is used for nuts and bolts with a recessed or enclosed head. Having both options in one tool allows for more efficient and effective work.

The given statement describes a wrench that is both L-shaped and hexagonal. The term "hex key wrench" is commonly used to refer to a tool that is L-shaped and has a hexagonal shape at the end. This type of wrench is designed to fit into hexagonal-shaped sockets or bolts, allowing for effective tightening or loosening. Therefore, the correct answer is "hex key wrench."

An open-end wrench is the correct answer because it has an opening on each end, allowing it to fit over nuts and bolts of different sizes. This design makes it easy to slip the wrench onto the fastener, even in tight spaces where a box-end wrench may not fit. The open-end wrench is commonly used for quick adjustments and is a versatile tool in many industries and applications.

A ratchet is a tool used to turn a socket. It is designed with a handle that can be moved back and forth, allowing the socket to rotate in one direction while preventing it from rotating in the opposite direction. This mechanism is useful for tightening or loosening bolts or nuts in confined spaces where a regular wrench may not fit or where continuous rotation is not possible. The other options, a wrench and a pipe wrench, are also tools used for turning, but they do not have the ratcheting mechanism that allows for one-way rotation.

A square is a tool that is specifically designed for marking and measuring right angles. It has a straight edge and a perpendicular edge that allows for accurate alignment and measurement of objects to ensure they are at right angles. A spirit level is used to check if a surface is level or plumb, while a steel rule is a measuring tool with a straight edge for linear measurements.

A plumb bob is a tool that uses the force of gravity to make a line hang vertical. It consists of a weight attached to a string or cord, and when suspended, the weight aligns itself with the direction of gravity, creating a straight vertical line. This tool is commonly used in construction, carpentry, and surveying to ensure accurate measurements and alignments.

Long-nose pliers are the correct answer because they are specifically designed to reach into tight spaces, grip small objects, and bend wire. The long and slim jaws of long-nose pliers allow for precise and delicate work in narrow areas where other types of pliers might not be able to reach. They are commonly used in electrical work, jewelry making, and other tasks that require fine manipulation and control.

A box-end wrench is the correct answer because it is designed with a closed loop at one or both ends, forming a circle around the head of a fastener. This design allows for a secure grip on the fastener and prevents slipping or rounding of the edges. Open-end wrenches have U-shaped openings and do not form a complete circle, while hex key wrenches have a hexagonal shape and are used specifically for hexagonal fasteners.

Sockets are tools that are specifically designed to grip nuts or bolts. They have a hollow cylindrical shape with a hexagonal or square opening on one end, allowing them to fit over the nuts or bolts securely. Sockets are commonly used in conjunction with a ratchet, which provides the necessary leverage and allows for easy tightening or loosening of the nuts or bolts. A hammer, on the other hand, is not typically used for gripping nuts or bolts but rather for striking or driving objects.

A perfectly horizontal surface is called a level surface.

Tongue-and-groove pliers are the correct answer because they have serrated teeth that can grip objects of different shapes, such as flat, round, or hexagonal. This type of pliers is designed with adjustable jaws that can be locked into different positions, allowing for a secure grip on various objects. The term "tongue-and-groove" refers to the mechanism used to adjust the position of the jaws, making these pliers versatile and suitable for different tasks.

Lineman pliers are specifically designed for heavy-duty tasks such as cutting heavy wire and gripping objects. They have wide jaws that provide a strong grip and enable them to cut through thick wires with ease. These pliers are commonly used by electricians and linemen for various tasks in their line of work.

A perfectly vertical surface is called a plumb surface. The term "plumb" refers to a straight line that is perpendicular to the force of gravity. In construction and carpentry, a plumb surface is important for ensuring that walls, posts, or other structures are perfectly vertical. A plumb bob, which is a weighted object attached to a string, is often used to determine if a surface is plumb.

The correct answer is "locking" because pliers with an adjustable knob that controls width and tension for the jaws typically have a locking mechanism that allows the jaws to be locked in place at a desired width and tension. This feature is useful for holding objects securely and preventing them from slipping out of the jaws while working.

A folding rule is best for measuring vertical distances because it can be easily extended or folded to match the height of an object or the distance between two points in a vertical direction. It provides a convenient and accurate way to measure heights, lengths, or depths that are perpendicular to the ground or floor.

To ensure proper alignment and support of the bolt, it is necessary to hold the head of a torque wrench with one hand. The head of the torque wrench is the part that connects to the bolt and applies the torque force. By holding the head, you can ensure that the torque is being applied accurately and prevent any misalignment or damage to the bolt. Holding the handle alone may not provide the necessary control and stability required for proper alignment.
