In this paper a comparative investigation carried out on the shear behaviour of mechanical connections in thin gauge steel is described. The connection techniques considered are press joining, Henrob fasteners, pop rivets and self-tapping screws. Samples joining two strips of steel of 1.0-, 1.2-, 1.6- and 2.0-mm thickness are reported. Press joins are applied at orientations of 0°, 45°, and 90°. Peak loads of all types of join tested are tabulated. The variability of the peak loads of press joins and screw samples in 1.0-mm and 2.0-mm thick steel are established with six tests on each configuration. A variability analysis is also carried out on peak stresses obtained from elasto-plastic material tests on 1.0-mm and 2.0-mm steel samples. The load displacement responses of the four types of connection in the small displacement range of <0.1 mm are plotted and compared.
