The load-carrying capacity of connections with inclined screws can be increased due to friction in the shear plane. Surface modifications to increase the friction were investigated. Friction tests showed increased friction coefficients. Tests with connections showed increased load and stiffness values. An analytical model predicts the load well. This work provides insights into the short-term and long-term behaviour of connections with inclined screws and increased friction in the shear plane.
