Abstract
A screw member includes a main body having a first end provided with a head portion and a second end provided with a threaded portion. The head portion has a center formed with a substantially Y-shaped insertion recess including three locking grooves. The three locking grooves of the insertion recess of the head portion are equally divided portions of the circular head portion, so that the tip of the screwdriver is combined with the head portion in a co-planar three-point contact manner. Thus, the screw member is combined with the screwdriver rigidly and stably.
