Torx keys, also known as star bits, have a 6-point star-shaped pattern where the tip at the end of the shaft is inserted into the Torx indentation in the screw and the key is turned to rotate the screw. Torx tips provide a more secure grip on the fastener head, increase torque transfer, and are less likely to slip out of the head and damage the screwhead and adjacent surfaces compared to slotted head or Phillips head fasteners. Torx keys with a Torx ball end allow fasteners to be accessed from multiple angles in hard-to-reach areas. They can be L-shaped with two arms of unequal length, one long and one short. The short end can reach fasteners in tight spaces while the long end extends the reach of the tool. Rotating a fastener using the long end as a handle provides more torque on the fastener compared to using the short end. T-shaped Torx keys have one long arm with the drive tip at the end and a handle that can provide more torque when rotating fasteners compared to L-shaped keys.
