The KNAUF Drywall Screws TN 3.5×45 mm are high-quality self-tapping screws designed for securely fixing gypsum boards to metal stud framing systems. Manufactured by Knauf, these screws offer strong holding power, smooth installation, and reliable performance for professional drywall construction.

With a 3.5 mm diameter and 45 mm length, they are suitable for standard and thicker gypsum board applications where deeper penetration and stronger fastening are required. The sharp thread design allows easy driving into metal profiles without pre-drilling, ensuring faster installation and reduced effort on site.

These screws are widely used in drywall partitions, false ceilings, and interior wall systems in residential, commercial, and industrial projects. The 1000-piece box is ideal for contractors and bulk installation work.
