Drive-in torque for self-tapping screws into timber [PDF]
Proceedings of the Institution of Civil Engineers - Construction Materials, 2022 Self-tapping screws have been widely used in timber constructions. The current practice considers self-tapping screws perform best in connecting two members when they are fully threaded; however, the drive-in resistance caused by the friction between the wood and the screw can potentially damage the screw and reduce the effectiveness of its ...
