15mm screw. The fixing screw used with the connectors is self-drilling and self-tapping (create its own thread). This means holes do not need to be drilled, saving time, and there is no swarf created, ensuring protection of any waterproof membranes being used. The torque head reduces the possibility of damaging the head when fixing.
