Cill screws are precision fasteners designed for securely fixing window cills to uPVC, timber, and aluminium frames, ensuring a stable and weather resistant installation. Engineered for strength and reliable hold, they support proper alignment and long term structural integrity in glazing systems.
Manufactured with zinc plated (BZP) finishes for corrosion resistance, cill screws are available in multiple lengths to suit varying profiles and materials, providing consistent performance in both domestic and commercial window installations.
