Application:

The Allen key is ergonomically T-shaped for added grip and comfort when turning.
The handle also resists rotational distortion.

The Allen key features a ball end tip that guides the tip easier into a bolt. It
also allows the Allen key to swivel when turned. This is useful when fastening
bolts in awkward angles where standard Allen keys won’t reach.

NOTE:
Allen keys are also known as hex keys.
