Self-drilling screws for steel profiles – quick and reliable installation

Koelner WS-3595 self-drilling screws are a reliable solution for joining steel profiles and attaching gypsum plasterboard to metal structures. Thanks to their special design and tip, they allow drilling and screwing in one step, which significantly speeds up work both on construction sites and in workshops. The package contains 1000 pieces, making them an ideal choice for both professionals and those undertaking DIY projects.

Design and application

WS-3595 screws are characterized by a diameter of 3.5 mm and a length of 95 mm. Made of low-carbon steel with a phosphate coating, they provide corrosion resistance and durable connections. Phosphating is a chemical process that increases the adhesion of anti-corrosion coatings and also improves lubricating properties – which translates to easier installation. They are particularly recommended for use in drywall systems where fast and precise installation is required. The ability to drill up to 2.0 mm allows work with different thicknesses of steel profiles.

Advantages in practice

• Fast installation: The self-drilling tip eliminates the need to pre-drill pilot holes, saving time and effort.
• Secure connection: The thread matched to steel ensures stable and durable fastening of structural elements.
• Corrosion resistance: The phosphate coating protects against the effects of moisture and other corrosive agents, increasing the lifespan of connections.
• Versatility: Ideal for joining steel profiles and attaching gypsum plasterboard to metal.
• Convenient packaging: A large 1000-piece package minimizes costs associated with frequent restocking and facilitates storage.
• Universality: They will work both in professional construction installations and during minor repairs or renovation work.

Remember to use an appropriate screwdriver with a Phillips bit during installation – this will ensure optimal efficiency and safety. Avoid overtightening the screws to avoid damaging the thread or steel profile.
