The Diyuk Baypole Tek Screws are designed for professional window installers and DIY enthusiasts looking for a secure, flush-fitting connection between UPVC window frames. These high-performance screws excel at penetrating internal aluminium or steel reinforcements without the need for pre-drilling, though users must be careful to avoid over-tightening to prevent stripping the thin-walled UPVC profiles.

No, the self-drilling tek point is designed to pierce through aluminium or steel reinforcement up to 3mm thick.
They feature a high-quality corrosion-resistant finish designed for exterior use, though regular maintenance is recommended in coastal areas.
These are specifically engineered for UPVC windows with metal reinforcements and may not provide the same pull-out strength in timber.
Over-tightening can strip the thread in the reinforcement or damage the plastic frame profile; always use a clutch-controlled drill.
Yes, if necessary, the heads can be painted to match specific frame colors, though the factory white finish is durable.
Apply consistent pressure and ensure you are drilling through the metal reinforcement rather than just the PVC layer.
Ensure you are using the correct bit size and check that the driver bit is not worn down.
Use clamps to hold the frames in place before driving the screw to ensure the threads have maximum engagement.
To ensure the best connection, start by clamping your frames securely in their intended position to prevent gaps. Align the screw perpendicular to the frame surface to prevent the tek point from skipping. Since the screws are finished in a white coating, handle them carefully with clean hands to avoid transferring grime onto the screw head or the frame profile. Store the remaining screws in a dry environment; while they are corrosion-resistant, high humidity in storage can eventually degrade the finish before installation. Always ensure you are using a correctly sized Phillips or Torx bit to prevent cam-out during the driving process.
