      Type approved decking screw that is ideal for working in tough environments and pressure-treated timber.

      The screw is part threaded which means that the decking board is clamped securely against the underlying joist. The shank also has a double helix to help remove debris form the hole and improve clamping even under low loads. Slash point tip to cut through the fibres of the wood efficiently for improved driving and reduced splitting. The ribs underneath the head of the screw help when countersinking into decking board.

      This decking screw is made of steel treated with an anti-corrosion coating giving it a corrosion class of C4 and is type-approved by SITAC (Swedish Institute for Technical Approval in Construction). The screw is much harder than a regular stainless steel screw and is recommended for use with hardwoods such as oak, ash and larch. Quick-drive screw with a high corrosion resistance making it ideal for exterior use on constructions which are exposed to corrosive environments or in direct contact with the ground such as jetty posts, concrete moulds and uncovered decking.

      The screw head has a T20 recess to provide a good drive with minimal risk of camming out.
