Higher strength steel makes it possible to reduce the weight of members without changing the cross-sectional shape. To apply high-strength steel to light-gauge steel structures, it is necessary to quantify the strength of screw connections. In this study, single plane shear tests of screw connections using high-strength steel were conducted, and an evaluation formula for the strength of the connections was proposed. It was shown that the evaluation formula was able to properly evaluate the strength of the screw connections.
