Description
Window screws like these Timco 3.9 x 16mm ribbed window screws are designed for fitting hardware to reinforced window and door frames. 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 the screw sit neatly into suitable hardware and frame applications. The PH2 Phillips drive, self-tapping thread and self-drilling point make them a practical choice for fast fixing into reinforced window and door frame sections.
The zinc finish provides corrosion resistance for suitable 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.
