Design and application

WS-3911 screws are designed for efficient joining of structural elements in dry construction systems. Made of low-carbon steel with a phosphate coating, they are characterized by good corrosion resistance. Their diameter of 3.9 mm and length of 11 mm make them ideal for profiles with a thickness of over 0.7 mm. Phosphating is a chemical process that increases the adhesion of anti-corrosion coatings – thanks to this, the screws are more resistant to moisture and provide a durable connection.
