Abstract: A screw clamping tool includes a main body and an elastic clamping member. The main body has a driving portion having a driving bore which rotates about a rotation center for driving a screw member. A plurality of contact faces are disposed on an inner side of the driving bore, and a positioning groove concavely is formed on the driving bore. The elastic clamping member is formed of a non-metal material and disposed in the positioning bore and protruding on an inner edge of the driving bore with respect to the contact faces. When the screw member is received in the driving bore, the elastic clamping member stably clamps the screw member.

Abstract: A damaged screw member removing tool includes a main body having a hollow mounting portion at one end thereof, and an engage structure disposed in the mounting portion and having a plurality of forcing units with a recess portion disposed between each two of the forcing units. Each forcing unit includes a first and a second forcing faces connected to include an included angle therebetween. The first forcing face has a first forcing point at a lateral side thereof. The second forcing face has a second forcing point at a lateral side thereof. When the mounting portion is mounted on a damaged screw member, the first forcing face contacts a damaged corner of the damaged screw member, and the second forcing point rests on a lateral face of the damaged screw member, with other damaged corners housed in the recess portions.
