The present invention relates to a screw connector and methods of connecting elements, particulary in metal constructions using such screw connector. According to the present invention, screw connectors are useful for making temporary connections, which are suitable for the proper stabilisation of elements before realisation of the final welded joints. The screw connector comprises a threaded shank (1a) and a flat head (1b) with a hole, the thickness of the head (1b) being smaller than the diameter of the shank (1a). The head of the connector is limited by one plane (A) tangent to the surface of the shank, and a second plane (B) at a shorter distance from the shank axis wchich second plane transforms into a single sided bevel (1c) in the transition zone between the shank (1a) and the head (1b). Preferably, the thickness of the head (1b) is equal to half the diameter of the shank (1a) and the ratio of the slope of the bevel plane (1c) to the plane (B) of the head (1b) is equal to 1:1.
