Design and Features

Head Design: The most common feature of Window Screws is their head. Since they are intended for exterior windows, a non-protruding head, such as a flat countersunk head, is ideal. This ensures a smooth, flush finish.
Nibs: Many of our Window Screws come with nibs under the head. These nibs enhance the fixture on the window, providing a more secure and stable installation.
Thread Types: The threads on Window Screws range from fine to coarse, catering to different fastening needs. This variety allows for optimal performance based on the material of the window components.


Specifications

Diameter and Length: Our Window Screws come in various diameters, ranging from 3.5mm to 6.0mm, and lengths from 20mm to 120mm. This range ensures that you can find the perfect size for your specific application.
Surface Coatings: To enhance durability and resistance to corrosion, our Window Screws are available with several surface coatings, including zinc and yellow zinc. These coatings provide additional protection against the elements, ensuring longevity.
Functionalities

Self-Drilling and Self-Tapping Points: Window Screws are available with both self-drilling and self-tapping points, allowing for versatile use. The self-drilling point is typically rounded rather than the standard flat self-drilling points, making it more effective for metal applications.
Application Versatility: Depending on the material being fastened—whether wood, metal, or a combination of both—our Window Screws provide secure and reliable fastening solutions.


Applications

Exterior Applications: Designed to withstand external conditions, our screws are perfect for any exterior window installations, offering high resistance to weather elements.
