Accelerate your window manufacturing process with TIMCO Self-Drilling Window Fabrication Screws. Specifically designed for fitting a wide variety of hardware to PVCu frames with internal steel or aluminium reinforcements, these screws eliminate the need for time-consuming pre-drilling. Finished in a professional Yellow Zinc coating and featuring a classic countersunk head, they deliver a secure, flush fit and reliable corrosion resistance for high-volume fabricators.
Fast-Track Your Fabrication
When your PVCu window profiles contain internal steel or aluminium reinforcements for added rigidity, attaching hinges, locks, and keeps can severely slow down your assembly line if you have to pre-drill every hole. The TIMCO self-drilling fabrication screw completely bypasses this step. Equipped with an aggressive, hardened self-drilling point, it features a Maximum Drilling Thickness (MDT) of 2.5mm. This allows you to drive the screw straight through the plastic outer layer and directly into the metal core in one fluid motion, saving valuable seconds on every single fixing.
A Clean, Countersunk Finish
Hardware clearances on modern windows are incredibly tight. If a screw head sits too high, it can scrape against the opposing frame, preventing the window from closing correctly or damaging the PVCu. These screws utilize a traditional countersunk head designed to drop perfectly into the pre-machined holes of standard window hardware. Once fully driven, the head sits entirely flush with the surface of the metal bracket, ensuring your locking mechanisms and friction stays glide past each other without interference.
Yellow Zinc Protection and Aesthetics
Manufactured from high-strength carbon steel, these screws are built for the rigorous demands of impact drivers and automated fabrication machinery. To protect the steel core, they are treated with a Yellow Zinc finish. This coating achieves a Corrosion Rating of 2, providing the exact level of protection required for the sheltered, occasionally damp environments found inside window rebates. Furthermore, the yellow passivation is an excellent aesthetic match for fabricators working with brass-coloured or similarly passivated window hardware, maintaining a consistent, professional look across the finished product.

Frequently Asked Questions
What is the difference between this and the "Zinc" version?
What is the difference between this and the "Zinc" version?
Functionally, they perform the exact same job with the same Corrosion Rating (2). The primary difference is the colour. The "Zinc & Yellow" finish is often preferred by fabricators who want the screws to visually blend in with yellow-passivated or brass window hardware.
Does this screw have milling ribs under the head?
Does this screw have milling ribs under the head?
No, this specific model features a standard smooth countersunk head. It relies on the countersunk hole in the metal window hardware to allow it to sit flush. If you need a screw that carves its own flush recess directly into the PVCu plastic, you should look for the "Countersunk with Ribs" version.
What does MDT 2.5mm mean for my frames?
What does MDT 2.5mm mean for my frames?
MDT (Maximum Drilling Thickness) indicates that the self-drilling tip can easily pierce through metal structural reinforcements up to 2.5mm thick without burning out or snapping.
