Abstract

A screw driving member of the present invention is driven by a power tool to turn a nut with a polygonal head and a slot on its top. The screw driving member includes a shaft, a driver head and a biasing device. The shaft has an axial hole and a fitting hole. The driver head is inserted into the axial hole of the shaft for reciprocation but rotation. The biasing device urges the driver head to have a coupling end out of the shaft. In engagement of the nut, the coupling end enters the slot of the nut, and then the driver head will be turned automatically that the coupling end may fully enter the slot. At the same time, the shaft is turned also that the fitting hole may be engaged with the head of the nut when the screw driving member is pressed downward.
