Description
The Timco 4.2 x 55mm cill screws are designed for attaching cills to the base of door and window frames. With a self-drilling point and self-tapping thread, they can drill through both reinforced and unreinforced frames, making them ideal for trade window fitting, frame installation and repair work.
These cill screws feature a PH2 Phillips drive and bugle head for secure driving and a neat finish. The 4.2mm diameter and 55mm length make them suitable for fixing cills where a reliable window screw is required.
The zinc finish provides corrosion resistance for suitable internal, sheltered and occasionally damp applications. Supplied in a box of 500, these Timco cill screws are ideal for window fitters, installers, fabricators and trade users carrying out regular PVCu frame and cill fixing work.
Always check the frame section, reinforcement and cill fixing requirements before installation. Use the correct driver bit and avoid overtightening to prevent damage to the frame or fixing point.
