Description
Baypole screws like these Timco 4.8 x 40mm screws are designed for joining PVCu bay window sections, bay poles and window frame assemblies. They are suitable for trade window fitting, frame installation and door or window fabrication work where a strong 40mm fixing is required.
These Timco baypole screws feature a wafer flange head, PH2 Phillips drive and self-drilling point for fast, secure installation into suitable frame and reinforced materials. The self-tapping V flute thread helps create a strong fixing, while the zinc finish gives a clean, professional result for sheltered and occasionally damp applications.

How to Use Baypole Screws
Select a compatible PH2 Phillips driver bit and position the frame section or bay pole correctly before fixing.
Drive the screw steadily through the fixing point, keeping the driver straight and controlled. The self-drilling point helps the screw cut into suitable materials, while the wafer flange head provides a neat fixing surface.
Do not overtighten the screw. Once fitted, check that the bay pole or frame section is secure and correctly aligned.
