Self-tapping screw 4.2x13mm-button LN/16 TECHNOGYPS

The self-tapping screw "button" type from the LN/16 series of the established manufacturer TECHNOGIPS PRO is a specialized high-quality fastener designed for connecting metal profiles and sheet metal parts in drywall systems. The LN indexing determines the specific low-profile head with a wide periphery and a sharp needle-shaped tip with a fine thread, which is optimized for quick and secure fixing of metal elements without pre-drilling. With its precise dimensions of 4.2 x 13 mm, this screw provides a strong and stable mechanical connection between the profiles, guaranteeing the correct geometry of the supporting structure.

The wide flat head of the screw ("button" type) provides an extremely large contact area, which prevents the sheet metal from slipping and distributes the load evenly on the assembly unit, while not interfering with the subsequent laying of the plasterboard panels. Made of high-quality phosphated metal, this screw has excellent protection against corrosion and construction moisture on the site. Its high performance is proven by the drilling time of metal profiles with a thickness of up to 0.7 mm, which is less than 2 seconds. The screws cover the highest European fire reaction class (A1), which makes them completely safe for the construction of partition walls and suspended ceilings.

Purpose:

• Connecting and fixing metal profiles such as CD, UD, CW and UW to each other
• Assembly of metal substructures and frames for drywall construction
• Fixing hangers, discs and other mounting accessories to steel profiles
• Use in assembly work with thin sheets and metal substrates up to 0.7 mm thick

Main advantages:

• Black phosphate coating for long-lasting protection against corrosion and the effects of mortars
• Low-profile head with wide periphery for maximum clamping area without raising the surface
• Extremely sharp needle tip for quick centering and fixation without slipping of the tool
• Saves time on site with fast drilling in under 2 seconds for greater efficiency
• Highest fire safety class A1, compliant with security requirements for public and residential buildings
