The TX drive allows for optimum torque transmission, a tight and snug fit, and fast centering.

The raised countersunk head with milling pockets and small diameter, gives a discreet and subtle appearance and ensures that the head can sink cleanly and easily.

The asymmetrical thread enables the screw to feature a reduced drive-in torque, a high overtorque, and makes them easy to screw in.

An optimised drilling tip for deck construction allows for quick, easy and safe positioning and installation, as well as reduced splitting of the timber.

The stainless steel grade of the screws (304/A2 and 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.

For best results, we recommend pre-drilling and pre-countersinking holes.
