Spax's T-Star Plus head provides a tight secure fit of the BIT which allows for better driving in, especially when working overhead. The drill point allows for the screw to self-drill into 4mm thick aluminium without pre-drilling. Delta-seal provides a highly corrosion-resistant coating of the screw that is twice as effective when compared to traditional galvanising. It is ideal for ACQ and CCA treated timbers as well as all hardwoods that are externally located and away from direct exposure to salt water.

The fixing thread provides a safe and permanent connection to eliminate screw heads popping up in the event of timber warping. Spax's cylinder head allows for easy countersinking and also reduces the chance of splitting wood all while providing a low-profile finish.
