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. Are Bondhus Allen keys good?

Our favorites there are the Bondhus 12522 Gorilla Grips. They were the least expensive ones we looked at, but they had the most comfortable handle and the most useful features. We liked how the wrenches can also be stopped at 90 degrees from the handle, which helps to quickly loosen or tighten a screw.

3. What are TX keys?

A Torx key is for tightening and undoing fasteners – bolts and screws – that have Torx (six-pointed, star-like) indents, or recesses, in their heads. While Torx keys may occasionally be available individually, they are more generally sold as sets, with different types available for various circumstances.
