The present invention pertains to a triangular shank with multiple threaded sections essentially including a head, a shank and a drilling portion. Wherein the shank has two opposite threaded sections formed in triangular and a third threaded section spiraling on the drilling portion. The third threaded section with a planar flank assists in enlarging the drilling track and providing guidance for those two threaded sections to easily enter into the object so as to efficiently extrude the debris out of the object and retain remaining debris for a better fastening effect. Further the triangular configuration results in the less contact between the screw and the object in time of screwing, thus reducing the frictional resistance and obtaining high screwing speed.
