Frequently Asked Questions (FAQs)

1. Is a hex key the same as an Allen key?

A hex key, also known as an Allen key is a simple tool used to drive bolts and screws with hexagonal sockets in their heads. From standard keys in chrome vanadium steel to extra-long with ballpoint heads in chrome molybdenum steel, there are a wide variety to choose from.

2. Why is an Allen key called an Allen key?

The “Allen screw” name for the socket head cap screw and “Allen key” for the wrench originate from the products of the Allen Manufacturing Company of Hartford, Connecticut. According to Bates, it is widely reported that the company trademarked the name “Allen wrench or key” for its range of hex wrenches in 1943.

3. Why is it called a hex key?

They are called “hex keys” because they use six points of contact. In other words, a hex key touches a half-dozen difference surfaces of the hex screw. The use of six points of contact allows the hex key to easily grab the hex key. If a tool uses five or fewer points of contact, it isn't considered a hex key.

4. How do you find the hex key?
