By the end, you’ll see what is a wrench, and how a wrench makes your job easier, and how to pick the right wrench to work with all your nuts or bolts. Not only that, you’ll see when the right wrenches are used; they make things much more accessible and easier to deal with.

Common Construction Wrenches

Here are a variety of wrenches that fit a buyer’s needs. Here is a rundown of common construction wrenches and what the wrench is designed for.

adjustable wrench

1. Adjustable Wrench

Adjustable wrenches are generally used in plumbing, stored in a utility drawer or toolbox. This wrench with a U-shaped opening is widely available and most often used among home tools.

No fixed size opening for nuts and bolts; it is an open-ended wrench.

Its thick structure makes it difficult to use in confined types compared to other wrenches. Determining the correct size of an adjustable wrench is important. (Read Wrench Sizes Chart)

With these wrenches and their uses, you can adjust the size by turning the base’s screw.

Crescent Wrench

The first type of wrench has adjustable settings. Regular wrenches can fit a wide range of nut sizes, but not this one. It is also known as the Crescent Wrench because of its shape.

Adjustable Monkey Wrench

The monkey wrench was a handyman’s tool; thus, you don’t need to buy a set of wrenches to tighten and loosen nuts of various sizes. Over time, adjustable wrench tools have surpassed the popularity of the monkey wrench.

Pipe Wrench

The wrench is similar yet slimmer to a monkey wrench for round surface fixtures. Its jagged teeth can hold softer metals while turning a pipe. In addition, it is easy to repair and thus reduces money on new equipment.

socket wrench

2. Socket Wrench

This is also known as a ratchet wrench and performs similar functions. You can tighten or loosen a nut or a bolt without removing the circular wrench handle.

It is also reversible for more versatility. The wrench may reach the obstacle, but you can quickly reverse it to continue working. Its socket mechanism speeds up the tightening and removing process.

A socket wrench accepts various socket sizes. The most common drive size is 3/8” to fit the socket. (Read Socket Sizes in Order from Smallest to Largest)

Look for a quality socket set with a size of socket sizes. Look for a quick-release button. Always choose the right wrench size, not too loose or too large. Keep them organized for long-term use.

Ratcheting Socket Wrench

It has a ratcheting mechanism that can install and remove a nut and bolt without lifting the wrench at every turn.

Flex Head Socket Wrench

The drive head is swiveling, not fixed. Unlike ratcheting wrenches, it is rarely used. This is true for small-space construction.

Nut Driver Socket Wrench

A nut driver would help tighten a hexagonal nut and bolt. It is operated manually and has a socket head.

T-Handle Socket Wrench

T-handle socket wrenches are another basic type. On each end, it has a long vertical and horizontal beam. To fasten the bolt, simply grip the horizontal beam and insert the socket head.

3. Allen Wrench

An Allen wrench is a hex key wrench, which comes in two shapes: L and T. The T-shaped option has a handle.

Both wrenches are metal and work like regular screwdrivers. To easily fit screws and bolts, a male-style wrench has a hexagonal recess on its head.

Allen wrenches’ high torque allows them to work with extra-tight screws when you turn the wrench.

L/P/T Shaped Wrenches

It is an L-shaped, P-shaped, or T-shaped hexagonal key wrench. The T-shaped option has a handle. Both wrenches are metal and work like regular screwdrivers. The P-shaped wrench is the oversized L-shaped wrench.

An L-shaped wrench has a different handle for working on deeper screws. Its shorter end can be used as a handle. Overall, the Allen wrench may be best for more difficult maintenance and repair tasks.

4. Combination Wrench

Combination wrenches combine a box-ended, closed wrench end and an open-end wrench in one tool. An open U-shaped wrench for hex and square nuts is on one side.

The closed-end loosens the nut or bolt while the open end unscrews them. However, both ends have similar sizes.

A combination wrench uses are far and wide, so it is the most versatile type of wrench.

Stubby Wrench

Stubby types of wrenches are a combination wrench’s shorter version. Its shorter shaft allows it to fit in tighter spaces.

Some units have a hinged head for better fitting a nut or bolt in tight areas. Unlike long wrenches, it is highly versatile for combination wrench use.
