Drywall screw 3.5x55mm TN, 12 TECHNOGIPS

The TN/12 series drywall screw from the proven manufacturer TECHNOGIPS is a high-quality fastener with a sharp tip, designed for reliable construction of massive drywall systems. The TN indexing defines the specific trumpet head of the screw and its sharp needle-shaped tip with a fine thread, which provides quick drilling of metal substructures up to 0.7 mm thick. With its impressive length of 55 mm, this model is the longest in the product line, which makes it indispensable when fixing multi-layer sheathing (for example, triple layer of drywall) or when working with specialized thick boards requiring deep and secure anchoring in the supporting profile.

The trumpet shape of the head allows smooth entry and perfect sinking into the surface of the plasterboard without tearing the front paper layer, which provides a clean base for subsequent grouting and plastering. Made of high-quality metal with a black phosphate coating, this rapid screw has excellent protection against corrosion and construction moisture on the site. Its exceptional efficiency is proven by the profile drilling time, which is less than 2 seconds. The screws cover the highest European fire reaction class (A1), making them a mandatory component for the construction of fire-resistant partition walls, suspended ceilings and shaft walls with high resistance requirements.

Purpose:

• Installation of multi-layer plasterboard sheathing to metal profiles such as CD, UD, CW and UW
• Construction of solid partition walls, suspended ceilings and pre-wall cladding with increased thickness
• Fixing plasterboard with a metal substructure thickness of up to 0.7 mm
• Use in drywall construction for details requiring maximum fastener length

Main advantages:

• Black phosphated coating for high resistance to corrosion and building moisture
• Trumpet-shaped head protects the cardboard surface from tearing and damage when tightening
• Maximum body length (55 mm), ideal for complex multi-layer systems and massive structures
