Drywall screw in accordance with EN14566:2008+A1:2009/Class 24/UMN

With its head with locking teeth, the profile connection screw is suitable for its intended purpose of tightly connecting two metal profiles

Head with locking teeth


  • When the screw is tightened, the locking teeth bond particularly tightly to the base material and the transferred forces reduce the risk of the screw loosening. This is particularly important for metal profiles with low material thickness.

Special thread geometry


  • The double-threaded self-tapping screw thread enables secure screwing and good load transmission to the connected components.

Extra pointed screw tip


  • The extra pointed screw tip enables very fast biting and secure screwing in metal profiles with a thickness of up to 1 mm per component.

Suitable materials or surface coatings, such as stainless steel or hot-dip galvanised fasteners, must be used in damp rooms and outdoors. (DIN 18360:2019-09)
The user is responsible for design considerations.

The profile connection screw is used in the processing of metal profiles (U-profiles, C-stands and other metal profiles for substructures up to 1 mm thickness per component) in acoustic and dry walling applications.
