Description
The Timco 3.9 x 19mm window screws are countersunk window fabrication screws for fitting hardware to frames where steel or aluminium reinforcement is present. They are suitable for trade window fitting, PVCu frame fabrication, frame hardware installation and repair work.
These window screws feature a countersunk head with ribs under the head for improved countersinking, helping create a neat finish when fixing into suitable reinforced frame sections. The PH2 Phillips drive and self-drilling point allow fast installation, while the self-tapping thread helps create a secure fixing.
The zinc finish provides corrosion resistance for suitable rural, sheltered and low-humidity applications. Supplied in a box of 1000, these Timco window fabrication screws are ideal for installers, fabricators and trade users who need a reliable bulk fixing for window frame hardware work.
These screws are designed for window frame hardware applications where the correct screw type, length and fixing method are important. Always check the frame section, reinforcement and hardware manufacturer guidance before installation.

How to Use
