Ceiling self-tapping screw with cross recess

The ceiling self-tapping screw with cross recess features an extended length, ranging from 50 mm to 150 mm. The standard shank diameter is 4.8 mm. These features allow fastening plasterboard sheets, fiberboard panels, wooden battens and other flat items to a ceiling frame. The fastener has a countersunk head with a recess for a Phillips screwdriver or driver bit. When driven in, the screw fully sinks into the body of the fastened material, leaving the top of the head flush with the surface of a suspended or surface-mounted ceiling.

For work with plasterboard, MDF, wood-based sheet materials and metal under 0.9 mm thick, sharp-point ceiling screws are used. For thicker metal sheets, self-drilling screws are used. Both types of fasteners are made from high-strength alloy steel with a coating applied by hot-dip or electrolytic galvanizing, as well as yellow zinc passivation.
