Allen Keys

Allen keys are also known as hex keys or hex wrenches. These are simple hand tools that belong to the socket and spanner family. These keys are used for tightening and loosening hexagonal bolts and other compatible fasteners.

The hex or allen keys are often seen as a single piece of steel formed into a small L-shape. With this raw format, you can find several variations from one manufacturer to another. Each of these available options is suitable for doing specific jobs. However, in any case, they are a highly versatile and fundamental tool for driving and fastening. And they are exclusively used across an array of application and product categories. For the same reason, most professionals and habitual DIY individuals own a few sizes of hex keys.

Types of hex keys you can find in the market today

There are several types of hex wrenches that you can find in the market today. Many of these closely adhere to the initially designed blueprints. However, some manufacturers have added their features or design aspects to make an updated basic model. Commonly a hex key set contains a one-piece hexagonal shaft steel tool in varying sizes. In addition, based on the supplier and brand, there can be slightly exotic versions available in hex key socket sets. Here we will elaborate on some common types of Allen keys that you may use in a lifetime.

T-handle hex keys

These keys have a t-shaped handle. They are a famous tool with automobile enthusiasts and mechanics because the T-shape offer user luxuries that standard hex keys do not. The unique shape offers a better grip as compared to the L-shape. In addition, it allows significantly increased torque because the additional weight of the T-handle offers a counterbalance that will help to seat the tool securely and firmly in the fastener head.  However, a trade-off is that these keys can be less versatile when you need to access smaller places with low clearance around the fasteners.

L-style and P handle wrenches

The L style is a standard Allen key that is easily available online. Here the L-shape helps you reach the tightest spots while serving all the control needed. So, if you are looking for getting only one Allen key socket set, the L-style is a perfect option to get most of the jobs done. There are many choices available in the market, but 1.5 – 10 mm is a valuable item to own. Likewise, P-handle Allen keys are a common tool in professional workshops. They are also depicted as oversized L-wrenches with a comfortable grip that benefits the same as a T-handle.

The ball end hex keys

These sets are also gaining popularity among both hobbyists and professionals. These keys offer versatility and a higher level of flexibility in terms of access to the smallest places. It is done by dramatically increasing the range of positions any user can stand in a while on it at a time. In addition, these keys feature a rounded hexagonal bulb at the driving end. One major advantage of this style is that it allows the hex key to be inserted into the fastener’s hexagonal recess at angles other than 90 degrees straight down. With several advantages, the simplistic design offers an amazing usability bonus.

Folding hex key and ratcheting drivers

Folding keys are mostly popular among cyclists and motorbike riders. Unlike any other hex key, it is almost impossible to lose a folding Allen key. This is because they are enclosed in the handle. These keys can fold out at 90 degrees from the storage handle, offering maximum torque. Whereas ratcheting hex drivers offer better speed as compared to most Allen wrenches. They are dynamic members of the family and are used with screwdriver bits and sockets. They are available in a wide range of sizes and styles.
