SIMPSON CSA4 3/8 X4 CSA | SIM-CSA4

Simpson StrongTie's 3/8 in. x 4 in. Torx T-15 CoarseThread ElectroGalvanized SharpPoint CSA Connector Screw balances performance and efficiency for builders and contractors. With its 6lobe Torx recess, the screw allows better driver engagement, reducing camout and speeding installation. Because the design is ETA approved per ETA04/0013, users can rely on published capacity values for both lateral and axial loads when fastening Simpson connectors. The coarsethread helps limit timber splitting, especially near edges or when working with dense species, while the sharp point enhances penetration, reducing predrilling time. In volume packs of 250, this screw is costeffective for framing, structural repair, and new construction projects.

• Designed for installing Simpson Strong-Tie 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
• 6-lobe recess helps to fix the screw during insertion
