1) The SIT® drive (TX compatible) allows for optimum torque transmission, a tight and snug fit, and fast centering.

2) The high efficiency thread with anti-friction coating reduces the drive-in torque.

3) An aggressive drilling tip with wings, cuts a clearance hole for decks with an aluminium under construction. It allows quick, easy and safe work without pre-drilling for aluminium thickness: 1.6 – 3.0 mm.

The stainless steel grade of the screws (316/A4) gives them a high corrosion and weather resistance, increased fracture torque, and makes them suitable for outdoor use and close to water applications.
