Designed specifically for professional fenestrators and tradespeople, the Diyuk Baypole Tek Screws offer a robust solution for connecting and reinforcing UPVC bay window frames. These high-performance screws provide a secure, flush finish that prevents interference with window mechanisms, making them ideal for high-stress installations. While they offer exceptional convenience by eliminating the need for pre-drilling, users should ensure their power tools are set to the correct torque to prevent stripping the screw heads or damaging the UPVC frame.

No, the self-drilling tek point is designed to penetrate UPVC, aluminium, and steel reinforcements directly.
Yes, they are heavily zinc-plated and galvanised to withstand damp conditions and resist rust.
No, the low-profile wafer head is designed to sit flush, ensuring trims sit flat against the frame.
A standard electric drill or impact driver with the appropriate driver bit is sufficient.
These are specifically designed for UPVC window systems with aluminium or steel reinforcements.
The hole may have become over-widened; move the screw slightly to a new location or use a slightly larger diameter fastener.
Ensure you are using the correct size driver bit and reduce the torque setting on your drill.
Verify the steel thickness is within recommended limits and use a high-speed, steady pressure technique.
To install, select an appropriate impact driver or electric drill. Ensure the screw is perpendicular to the surface before engaging the motor to prevent the point from walking. When working with thin-walled aluminium, apply steady, moderate pressure rather than excessive force to ensure the threads grab firmly. Regarding care, while the zinc-plated and galvanised finish is highly durable, avoid using harsh chemical cleaners or abrasive scouring pads directly on the screw heads, as this can degrade the protective coating and potentially lead to early oxidation.
