‍Have you ever been to a hardware store and seen a display of small, oddly shaped metal tools and wondered what they were used for? Chances are you were looking at a selection of best small wrenches, also known as Allen wrenches, Allen keys, or hex keys. These helpful tools are invaluable to any handyman or DIY enthusiast, allowing them to easily access and tighten screws and bolts in places that are hard to reach. While the most common type of Allen wrench looks like an L-shaped metal rod, there are many variations in size and shape to accommodate any job. Read on to learn more about this versatile tool and how it can be used around the house.

What are Allen wrenches?

An Allen wrench (or hex key, as it is also known) is an L-shaped tool with a hexagonal head that is used to turn screws and bolts that have a hexagonal socket in their heads. They are also commonly known as hex keys and are used frequently in the automotive and aviation industries, as well as by people who enjoy DIY activities. There are many different types of Allen wrench and their design allows them to fit perfectly into hexagonal screw heads, making it easy to tighten or loosen them. They come in a variety of sizes, with the most common being between two and three inches long and between 1/8 and 1/2 inch wide.

Types of Allen wrenches

There are many different types of Allen wrenches, each designed for a specific job. The three most common are the hex wrench, which is used for larger bolts; the hex key wrench, which is used for smaller bolts; and the hex bit wrench, which is used for screwdriver bits.

Hex wrench – This wrench is commonly used for nuts and bolts that are smaller than 1/4 inch in diameter. The hex wrench is between 1 and 2 inches long and between 5/16 and 1/2 inches wide.

Hex key wrench – This wrench is used to turn bolts that are smaller than 3/16 inches in diameter. It is between 1 and 2 inches long and between 1/8 and 1/2 inches wide.

Hex bit wrench – This wrench is used to turn screwdriver bits. It is approximately 1/8 inch in diameter.

How to use Allen wrenches

Before using an Allen wrench, you must determine what size wrench is needed for a particular job. If the screw or bolt head has markings on it, such as “8-32,” then the required wrench size is determined by the first two numbers (“8” and “32”). If the markings are not clear, you can assume that the required wrench size is 1/4 inch. To use the wrench to turn the screw or bolt, position the wrench parallel to the screw or bolt head.

Put the wrench’s L-shaped end into the socket of the screw or bolt head and turn it in the direction that loosens it. If the screw is stuck, try applying some light pressure while you turn the wrench. When turning a screw or bolt, don’t force it or you might strip the head. If it is too tight, apply a penetrating oil, like WD-40, to help loosen it up. Be sure to use the correct size wrench for each screw or bolt. If the wrench is too small, it won’t fit properly and you will risk stripping or damaging the screw or bolt head.
