Our 100-piece pack of Bay Pole Screws (4.8 x 70mm) is designed for high-strength structural bonding of uPVC window frames and bay poles. Featuring a self-tapping thread and a durable silver zinc finish, these screws provide a secure, corrosion-resistant connection for professional glazing installations.
High-Tensile Steel: Specifically case-hardened to drive through uPVC and internal steel reinforcements.
Silver Zinc Plating: Offers a clean, professional appearance and superior protection against rust and oxidation.
Self-Tapping Thread: Cuts its own path through the frame for a vibration-resistant, permanent hold.

Bay pole screws are specialized heavy-duty fasteners used by window fitters to join uPVC window profiles. The 70mm length is the most common size used for “coupling”—the process of joining two window frames together—or for attaching a frame to a structural bay pole or corner post. These bay pole screws ensure that the entire window assembly acts as a single, rigid unit, which is vital for the structural safety and thermal efficiency of a bay window.
In the glazing industry, fixings are often exposed to condensation and external moisture. Our bay pole screws feature a high-quality silver zinc plating that acts as a robust barrier against corrosion. This finish not only extends the life of the fixing but also ensures a clean aesthetic that blends perfectly with white uPVC frames and modern silver hardware. Unlike standard multi-purpose screws, these are engineered with the shear strength required to support the weight of heavy double or triple-glazed units.
At ECO HEAT SHOP, we supply fixings that simplify complex installations. These bay pole screws feature a sharp, precision-milled point and a deep-cut self-tapping thread. This allows the screw to bite instantly into the plastic and continue through any internal galvanized steel reinforcement without the screw head snapping or the thread stripping. The countersunk head is designed to sit flush within the frame’s track, allowing for a seamless finish that doesn’t interfere with window operation.

Installation Advice: When using bay pole screws, it is recommended to use a high-torque drill driver at a steady speed. While these are self-tapping, using a 3.0mm or 3.5mm HSS drill bit to create a pilot hole through the first layer of the uPVC frame can ensure perfectly straight alignment when driving into the central structural pole.
