With a deep six-lobe opening, these Torx screws prevent drivers from slipping and stripping drives. Also known as star drives, they withstand more torque than slotted, Phillips, and hex drives. The button head looks similar to a pan head, but it's lower and more compact, taking up less space.
Length is measured from under the head.
