The current design rules on screwed connections of light gauge steel for cold-formed steel structures are applicable for ambient temperature condition only. Investigation of screwed connections at elevated temperatures is limited. In this study, 27 single shear screwed connection specimens fabricated from G500 1.20 mm and G450 1.90 mm light gauge steels were conducted by using steady state test method in the temperature range from 22°C to 900°C. The coupon test results were compared with the predicted values calculated from the equations proposed by Chen and Young. Tilting and bearing failure mode was observed in the single shear screwed connection tests. The test results were compared with the predicted strengths calculated using the North American, Australian/New Zealand and European specifications for cold-formed steel structures. The reduced material properties were used in calculating the nominal strengths of the screwed connections due to the deterioration of material at elevated temperatures. It is shown that the strengths of the single shear screwed connections predicted by the specifications are generally conservative at elevated temperatures.
