Product Information
Full details
The Diyuk Baypole Tek Screws are precision-engineered fasteners designed specifically for professional installers and tradespeople working with UPVC bay window frames. These screws offer the primary benefit of self-drilling functionality, allowing them to penetrate internal aluminium or steel reinforcements without requiring time-consuming pre-drilling, though users should ensure they possess the correct driver bit size to avoid stripping the low-profile head during high-torque applications.

FAQs
Do I need to drill a pilot hole first?
No, these screws are self-drilling and are designed to penetrate aluminium or steel reinforcements directly.
Are these screws suitable for exterior use?
Yes, they are heavily zinc-plated and galvanised for high corrosion resistance, making them suitable for damp or exterior-facing window conditions.
Will the screw head obstruct the window frame seals?
The low-profile wafer head is specifically designed to sit flush, preventing interference with window operations or seals.
Can these be used on timber frames?
These are designed for UPVC bay window frames with metal reinforcement. They may not provide the necessary grip in solid timber.
What colour are the screw heads?
The screws have a white finish to match standard UPVC window frames.
Troubleshooting
Screw failing to penetrate the internal metal reinforcement
Ensure the drill speed is consistent and apply firm, steady pressure. If the reinforcement is thicker than standard, check that the screw tip is not dull.
Wafer head stripping during installation
Check that the driver bit is the correct size and not worn. Use a magnetic bit holder and maintain perpendicular alignment with the frame.
Pros and Cons
Pros
- Eliminates the need for pre-drilling holes in metal reinforcements
- Wafer head sits flush to prevent interference with window seals
- High corrosion resistance suitable for outdoor or damp exposure
- Provides a strong, rattle-free joint due to fine thread design
Cons
- Requires high-quality drill driver to prevent cam-out on the wafer head
- Not intended for non-reinforced UPVC sections
- Low-profile head may require specific bit types for optimal grip
Setup, Compatibility & Care
To ensure the best results, use a magnetic bit holder to maintain control over the screw during the initial drilling phase. While these screws are designed for self-drilling, ensure your power drill is set to a medium-high torque setting to penetrate the metal reinforcement effectively. Always verify the thickness of the reinforcement before installation to confirm the screw length is appropriate. While the zinc coating is highly durable, avoid over-tightening to the point of stripping the metal threads, as this will compromise the joint's integrity. Clean any metal swarf left behind after drilling to prevent surface discolouration on the white frame finish.
