Round head screw for fastening perforated steel plates to timber in outdoor and corrosive environments. The cylindrical shoulder interlocks with the plate hole, guaranteeing excellent static performance in steel-to-timber connections.

Connections can be calculated to Eurocode 5 for thick steel-timber plate connections, even with thin plates.
