What Are the Different Sizes of Self-drilling Screws?

In this article we give more information about the different sizes of Self-drilling screws, how to use them and the types of gypsum boards they are suitable for.

The Self-drilling screw is a bugle head drywall screw designed for fixing plasterboard to metal profiles with metal thickness up to 2.0 mm. Technogips Pro offers 4 standard sizes of self-drilling screw:

  • Self-drilling Screw TB 3.5 x 25
  • Self-drilling Screw TB 3.5 x 35
  • Self-drilling Screw TB 3.5 x 45
  • Self-drilling Screw TB 3.5 x 55

We recommend using Self-drilling Screw TB for interior application with plasterboard type A, type H2, type DF, type DFHL and Sound Comfort Extra type DFH2.

The screws are fixed with a drywall screwdriver which must be held perpendicular to the board, so that the angle between the board and the screw is 90 degrees. The screw head should penetrate 1 mm below the surface of the board, and the free end of the screw should enter at least 10 mm into the hollow space of the profile.

The different sizes of self-drilling screws are used as followed:

  • For one layer lining of plasterboard with standard thickness of 12.5 mm and a metal profile up to 2.0 mm, we use Self-drilling screw TB 3.5 x 25.
  • For the second layer of a two-layer lining of plasterboard with standard thickness of 12.5 mm and a metal profile up to 2.0 mm we use Self-drilling Screw TB 3.5 x 35. When the boards have an individual thickness of 15 mm, we use Self-drilling Screw TB 3.5 x 45 for the second layer.
  • For the third layer of a three-layer lining of plasterboard with standard thickness of 12.5 mm or 15 mm and a metal profile up to 2.0 mm, we use Self-drilling Screw TB 3.5 x 55.
