• Connecting steel profiles in dry wall and ceiling systems.
• Attaching gypsum plasterboard to metal supporting structures.
• Construction of partition walls, suspended ceilings and other structural elements using steel profiles.

Advantages and benefits – saving time and high quality

By choosing these screws, you gain not only a solid fastening but also a number of practical benefits:

• Self-drilling tip: Eliminates the need to use a drill, shortening installation time and making work easier.
• Durable carbon steel: Provides high mechanical strength and resistance to damage.
• Phosphate coating: Protects against corrosion, increasing the durability of the connection even in difficult conditions.
• Versatility: They work well both during renovation works and in new constructions.
• Economical packaging: 500 pieces in a carton is the optimal amount for larger projects, allowing you to avoid frequent purchases.
• Complies with DIN50942 standard: Confirms the high quality of the product and its safety of use.

Remember to use the appropriate PH2 cross-head bit for precise screwing and to avoid damaging the screw head. Screwing should be done perpendicularly to the profile surface – this will ensure maximum connection stability.
