Countersunk Self Tapping Drill Point Screw

Self Tapping Thread Screws with Drill Point and Countersunk Head are ideal for use as a window screw.

These screws, sometimes called Tek screws, host a Self-Drilling point. This removes the requirement for a pre-drilled pilot hole, reducing overall installation time and the need for additional tool bits.

The Self-Tapping thread allows the the screw to tap its own thread into the material, providing a secure and reliable fixing.

Countersunk Self Tapping Drill Point Screw, available in 3.9mm and 4.8mm thread gauge as standard.

3.9 Gauge – Ideal where there is an Aluminium or Steel reinforcement. Typically used for fixing a range of hardware to reinforced frames.

4.8 Gauge – Ideal where extra strength is necessary. Typically used for attaching hinges to Steel reinforced frames.

The Countersunk Head will sit flush within the target housing, offering a clean and aesthetic finish to any application.

Available from Fastenright in lengths ranging from 13mm to 60mm, with larger sizes available to order.
