Drywall Self-Tapping Screw

A self-tapping screw for drywall is selected depending on the density of the drywall and the task at hand. For looser, lower-quality material, it is better to use fasteners with a wide, coarse-pitch thread. These are also best suited for cladding walls and ceilings with gypsum board panels on a timber frame. Fasteners with fine threads are more reliable for fastening dense-structure gypsum board sheets to a metal profile frame. The self-tapping screw has a sharp tip and a countersunk or semi-countersunk head with a recess for a cross-head screwdriver. There are also versions with a hemispherical head and a press washer.

Drywall self-tapping screws are made from carbon steel alloys with an oxidized or zinc-plated coating. Fasteners 25 mm long are most commonly used for single-layer cladding, and 35 mm for double-layer cladding. The spacing between fasteners is usually kept within 200–250 mm. This value serves as the basis for calculating the number of screws needed to complete a given scope of work.
