CSA screws with a diameter of 4.0 and 5.0 mm are specifically designed and approved for steel sheet-wood connections. The precise fit of the shaft under the screw head ensures a force-locking load transfer to the hole edges of the connectors. The sharp cutting tip allows for accurate and immediate placement of the screw in the wood.

The edge distances and spacing between screws follow the same specifications as for the CNA 4.0 x ℓ comb nails. The load capacity values are regulated in the ETA.

Processing: A screwdriver with torque adjustment is explicitly recommended for driving in the CSA screws.

With European Technical Approval (ETA 04/0013).

CNA comb nails may be replaced by CSA screws according to the Simpson-StrongTie comparison without further proof. In the reverse case, evidence must be provided.
