Research on shear resistance of the steel sheeting plates with thickness from 0,50 to 1,50 mm connected by self‐drilling screws is undertaken and presented in this paper. One screw type with one diameter has been used. This kind of the single lap fastening is commonly used in a steel sheeting. Experimental and theoretical data about a connections slip and shear stiffness is a one of most important issue in case of a stressed skin diaphragm action problems. At the present practice the linear model of connections is effectively used however for more advanced analyses, the non‐linear models have to be taken into consideration. These are necessary in case of the advanced design and implementation of the stressed skin action in the steel structures covered by the corrugated metal sheeting. Such a model study is presented herein which intend to investigate the general connection behaviour where the main selected variable is the plate thickness. The test are performed according to the current standards EN 1990 and ECCS handbooks. It leads to a statistical evaluation of proposed functions for the design slip of fasteners and its limits. The theoretical basis of experimental tests under the shear load is presented.
