Window Frame Screw, with Countersunk Head TS30

Is this suitable for window frames?

This product is a window frame screw designed for use with window frame applications, helping to create a secure fixing. The countersunk head sits flush for a neat finish on compatible materials, which is commonly required when fitting window frames.

Will the 72 mm length work for my installation?

The screw length is 72 mm. It is typically chosen based on the thickness of the window frame and the material being fastened into. If you match the screw length to your frame and substrate depth, you can achieve a strong fixing without using a screw that is too short or too long.

What drive system do these screws use?

These screws use a T Star or Torx drive, which provides good engagement during driving. Using the correct driver size helps reduce cam out and makes installation easier, particularly when fitting multiple screws.

Do they have a fully threaded shank?

Yes, they feature a fully threaded design. This helps the screw grip more consistently along its length, which can be beneficial when securing window frame components where a steady bite is needed.

How many screws are included in this pack?

This pack contains 100 screws, making it convenient for larger jobs or multiple window installations. Having enough screws on hand can also help maintain consistent fixing throughout the work.

Are the screws protected against corrosion?

The screws have a zinc plated low friction coating. Zinc plating is commonly used to improve corrosion resistance, and the coating also helps the screw drive more smoothly, especially when you are installing in materials that require accurate alignment.

What size pilot hole might be needed?

Pilot hole requirements depend on the substrate and your fastening approach, but using the correct pilot hole size helps prevent splitting and supports cleaner driving. If you are unsure, check your window frame installation guidance or consider matching the pilot hole size to the screw thread diameter of 7.5 mm.

Can the countersunk head sit flush?

These screws are supplied with a countersunk head with an 11 mm head diameter. When used with compatible countersunk or prepped surfaces, the head can sit flush for a tidy finish and improved appearance.
