Window construction

Screws for window construction must be designed to ensure a reliable hold both in soft plastic and hard steel whilst also withstanding the high stress caused by window operation. With their special point geometry, SPAX window construction screws ensure sturdy connections.

The main facts at a glance:

  • Materials that can be difficult to install pose particular challenges for screws.
  • As a result of high loads, screws also need to be ultra-sturdy – all while being much smaller than standard screws.  
  • Professionals and DIY enthusiasts alike will find the perfect solution in the FEX range of window construction screws – for every task and every material. 

Window construction is a project with special requirements. Not only for DIY enthusiasts and professionals themselves, but also for their screws. After all, windows are made of a wide range of different materials, and some make installing window fittings nothing short of a Herculean feat. Like thin profiles made of plastic and metal, for instance, or material combinations like plastic profiles with internal steel reinforcement. So how can such projects still succeed? With SPAX, of course.

What else should be kept in mind?

 

The thread on screws has to be designed to ensure a firm hold in both softer, thinner materials like plastic and in hard steel. As a result of the high dynamic load when operating a window and the often heavy weight of window sashes, the sturdy connection of window fittings is crucial. This is no easy task with comparatively small screws. The screws also need a special point geometry capable of enabling fastening in wood, plastic and metal.

What solutions does SPAX offer?

 

Every challenge has its solution. And every solution is available at SPAX: with the FEX window construction screws, SPAX offers DIY enthusiasts and professionals a comprehensive range of perfect screws for every material and task. The FEX-A window frame-drilling screw is suitable for fastening fittings to plastic profiles with steel reinforcement fitted flush with the reinforcement chamber (up to 2 mm wall thickness). The FEX-KS fitting screw enables the fastening of fittings on plastic profiles without steel reinforcement.  The FEX fitting screw is ideal for fastening to PVC and wooden profiles. The FEX-H fitting screw, on the other hand, is only suitable for fittings on wood. The FEX-RS roller shutter screw is screwed into the frame profile with its self-drilling design and enables the simple installation of attachments. The FEX combi screw is used for plastic windows with steel reinforcement: the fine thread with drill point is designed for use in metal; the coarse thread is intended for use in plastic. As you can see, SPAX really has thought of everything.
