CSA-S connector screw is made from A4 marine grade stainless steel. It was developed for installing Simpson Strong-Tie stainless steel connectors to timber, in order to obtain the published load bearing capacities. The conical shape under the head ensures a full contact with the connector which increases the transfer of force. A fixed connection with larger cross-bearing capacity than for standard screws is obtained. The 6 lobe recess helps to fix the screw during insertion.
