Self-Tapping Screws for Gypsum Fiber Board

Self-tapping screws for gypsum fiber board (GFB) are shortened steel fasteners with a cross-recess head and an elongated, tapered shape. Their distinctive feature is the double thread. It allows a clean hole to be made in the gypsum fiber board. The screws are driven deep into the material so that they are practically invisible. This makes it possible to conceal the fastening seams and gives a neater finish.

Features of working with gypsum fiber board screws

Screws for gypsum fiber board are used not only for fastening the homogeneous material itself, but also when installing GFB onto metal frames or wooden battens. Thanks to the double thread, these metal products:

1. Hold securely even on concrete bases.
2. Reliably join parts regardless of the type of driving tool used: cross-head screwdrivers or power drivers.
3. Are made short: the standard size of a GFB screw is 3.9 mm in diameter and 19 mm in length. The double thread allows parts to be fastened without the screw “boring” deep into the material. However, if several layers of gypsum fiber board are to be joined, fasteners with a length of 25 to 45 mm can be purchased.

If extensive renovation work is planned, it is recommended to buy GFB screws in strips (collated).

Scope of application

Screws for gypsum fiber board are used for:

• wall cladding;
• building partitions in bathrooms;
• dry floor screed;
• installing GFB on ceilings, etc.

These metal products ensure reliable fixation of the gypsum fiber board. They will not come loose from their sockets, and the material around them will not be damaged.
