Description
The Timco 3.9 x 25mm 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, PH2 Phillips drive and self-drilling point for fast fixing into suitable reinforced frame sections. The self-tapping thread helps create a secure fixing, making them useful for installers, fabricators and window repair teams.
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 regular trade use where a reliable bulk fixing is required.
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.
