Streamline your window manufacturing and installation process with TIMCO 4.3 x 25mm Window Fabrication Screws. Specifically engineered for attaching friction stays with countersunk holes to PVCu frames, these specialized fasteners offer a superior alternative to standard single-thread screws. Featuring an advanced High-Low thread design and a rapid-piercing slash point, they guarantee exceptional speed of insertion and maximum pull-out resistance for reliable, long-lasting window assemblies.
Engineered for PVCu Fabrication
Standard screws often strip or pull out when driven into PVCu window frames, compromising the security of the window friction stays. TIMCO has engineered this specific fabrication screw to solve that exact problem. By utilizing a highly effective "High-Low" thread pattern, the screw bites aggressively into the plastic substrate. The higher thread cuts a deep path for maximum hold, while the lower thread packs the material tightly against the shank. This dual-action design drastically increases pull-out resistance, ensuring your heavy window vents remain securely attached for years to come.
Speed and Precision combined
In a fast-paced fabrication environment, every second counts. These screws feature a sharp "slash point" that instantly pierces the PVCu profile, eliminating the need to pre-drill in many applications and preventing the plastic from cracking or bulging. Once driven home, the shallow pan countersunk head does its job perfectly. It is specifically profiled to drop neatly into the countersunk holes found on metal friction stays, sitting entirely flush so it doesn't scrape or bind when the window is opened and closed.
Industry-Approved Reliability
When fabricating windows to modern building regulations, you need fasteners with proven pedigree. These TIMCO screws are manufactured from durable carbon steel and are rigorously tested to BS EN ISO 9227:2006 standards in UKAS-accredited facilities. Furthermore, their design and performance are strictly in accordance with BS 7412, alongside the guidelines set out by the British Plastics Federation (BPF) and the Glass and Glazing Federation (GGF). With a protective zinc finish, they offer the necessary resilience for sheltered and occasionally damp areas, providing total peace of mind for both the fabricator and the end user.

Frequently Asked Questions
What does a "Corrosion Rating 2" mean?
What does a "Corrosion Rating 2" mean?
A Corrosion Rating of 2 indicates that the zinc finish is designed for indoor use or environments that are only occasionally damp/wet, such as sheltered rural areas or the internal rebates of PVCu window frames.
Why use a Shallow Pan Countersunk head instead of a standard countersunk?
Why use a Shallow Pan Countersunk head instead of a standard countersunk?
Friction stays (window hinges) are made of relatively thin metal with shallow countersunk holes. A standard countersunk screw is too deep and would protrude, potentially catching on the hinge mechanism. The shallow pan countersunk head sits perfectly flush in these specific brackets.
Will I need a special drill bit?
Will I need a special drill bit?
No, these screws use a standard Phillips size 2 (PH2) driver bit, which is universally available and likely already in your toolkit.
