With the Spax chipboard screw 6 x 160 mm, you build strong and weather-resistant timber structures with total confidence. The 4CUT point displaces wood fibers to minimize splitting, allowing fast driving into softwoods without the need for pre-drilling. Equipped with a t-star plus T30 drive, it prevents bit cam-out and ensures smooth, direct power transfer with every turn. The partial thread design with a 65 mm thread length pulls heavy timber components firmly together without gapping, while the countersunk multi-head sinks flush for a clean surface finish. Made from durable A2 stainless steel, this screw reliably protects your outdoor decking, timber framing, and exterior woodwork against rust and weather exposure.
