Abstract: A screw includes a shank defining an exposed surface portion, a head and a drill section disposed at two opposite ends of the shank, and thread convolutions spirally disposed in a spiral direction and axially spaced apart. Each thread convolution has an upper thread flank and a lower thread flank. A groove is recessedly formed in the surface portion and extends annularly in the spiral direction, and a plurality of slots are recessedly formed in the surface portion and extends axially from at least one lower thread flank to meet the groove. Accordingly, the groove and the slots are adapted to enlarge spaces for moving and accommodating chips, thereby attaining a quick removal of chips, reducing screwing resistance, and accelerating a screwing operation. The accumulation of remaining chips within the groove and the slots facilitates a tight engagement between the screw and a workpiece and attains an anti-loosening effect.
