What is the difference between T-shaped and L-shaped keys?

T-shaped hex key sets (unlike L-shaped keys) feature one long arm with a drive tip at the end, along with a handle for delivering more torque when rotating fasteners.

What is the difference between long end & short end handle keys?

Rotating a long end handle key delivers more torque on the fastener, as compared to using a short end handle key.
