Product Information
Fermacell Screws 3.9 x 22mm β Box of 1000
Fermacell 3.9 x 22mm screws are purpose-designed fixings for Fermacell gypsum fibre boards.
The screws feature an optimised thread, sharp point and self-countersinking head to provide a secure fixing while allowing the screw head to finish neatly within the dense gypsum fibre surface.
This box contains 1000 screws and is particularly suited to Fermacell High Performance Fibre Boards, including the 30mm Fermacell 2E31 Acoustic Overlay Board.
Key Benefits
- Designed for Fermacell: developed specifically for use with dense Fermacell gypsum fibre products.
- Self-countersinking head: allows the screw to finish neatly and flush with the board surface.
- Optimised thread: designed for fast penetration and a secure fixing.
- No pre-drilling required: helping speed up installation.
- Corrosion-protected finish: suitable for standard internal dry construction applications.
- PH2 drive: compatible with standard PH2 driver bits.
- 1000 screws per box: suitable for larger flooring and dry construction projects.
Recommended Application
The 3.9 x 22mm screw is particularly suitable for fixing Fermacell flooring joints.
Recommended with:
The 2E31 flooring element incorporates a gypsum fibre construction with an acoustic wood-fibre layer and is installed as part of a dry screed floor system.
Fermacell Wall & Ceiling Boards
Fermacell gypsum fibreboards are also used extensively for wall and ceiling constructions. Different board thicknesses and system build-ups may require different screw lengths, so the fixing specification should always be checked before installation.

Installing Fermacell Flooring Elements
Fermacell flooring elements are typically installed by bonding the rebated joints and mechanically securing the overlapping board layers using the appropriate Fermacell screws or approved staples.
The screws secure the boards to one another while the joint adhesive cures. They are not intended to fix a floating Fermacell flooring element directly through to the structural subfloor.
Typical flooring screw consumption: approximately 15 screws per mΒ² may be required for suitable Fermacell flooring element installations.
Always follow the latest Fermacell flooring installation instructions for the specific element being installed.
