Self-drilling screw 3.5x9.5mm LB/42 TECHNOGYPS

The self-drilling screw from the LB/42 series of the leading manufacturer TECHNOGIPS is a specialized fastener designed for reliable and quick connection of details in drywall construction. The LB indexing determines the presence of a specific "drill" type tip (TEX), which allows the screw to independently drill metal components without the need for pre-prepared holes. With its precise dimensions of 3.5 x 9.5 mm, this model provides a strong mechanical assembly, capable of fixing elements with a total sheet metal thickness of up to 2.0 mm, which guarantees the structural stability of the entire supporting system.

The screw features a hemispherical low-profile head that provides excellent clamping without interfering with the subsequent installation of plasterboard panels on the profiles. Made of high-quality phosphated metal, the fastener has proven resistance to corrosion and construction moisture on the site for 48 hours in salt fog. Its exceptional performance allows drilling into steel elements in under 2 seconds, which drastically reduces work time. Covering the highest fire reaction class (A1), this product ensures complete fire safety in the construction of partition walls and suspended ceilings.

Purpose:

• Connecting and fixing metal profiles such as CD, UD, CW and UW to each other
• Attaching direct hangers and mounting brackets to CD 60 profiles
• Assembly of thick sheet metal substructures for plasterboard in drywall construction
• Use in assembly work on metal elements with a total thickness of up to 2.0 mm
