An element for use in an annular metal belt (1) is disclosed. The annular metal belt (1) transmits torque between two pulleys each having a V-shaped groove. The element has a flank capable of making frictional contact with the V-shaped groove for transmission of torque. A plurality of threads are disposed on the flank substantially in parallel to one another. The threads has a slight height relative to a dimension of the flank, and the top section of each thread is substantially planar.
