Cross Flat Drywall Screw Metric

Our factory specializes in producing high-strength cross countersunk head drywall screws. Made from high-quality carbon steel, they undergo carburizing heat treatment, achieving a surface hardness of 45-53HRC. The threads are coarse thread self-tapping type, with a pointed tail, and are designed with a cross recessed countersunk head, making them widely used in installation and other scenarios. The main specifications are M3.5, with lengths ranging from 16mm to 70mm, and we have ample stock of conventional sizes.

Product Description

The head features a 90-degree bellmouth counterbore, ensuring that the screw head is flush with the board surface after installation, without protruding. When applying putty and painting emulsion paint on the wall, there's no need to fill nail pits; the putty can be directly applied and the surface will be smooth. If round-head screws are used, each pit would have to be filled with putty individually, but this step is eliminated with counterbored screws.

A deep cross slot allows the screwdriver bit to engage firmly. When a decorator uses an electric screwdriver for a whole day, the slot opening is not easily rounded. Another advantage of the cross slot is that screwdriver bits are easy to find, and any cross screwdriver can be used for tightening.

Simply align with the electric screwdriver and drive it in directly. The thread profile design takes into account the characteristics of gypsum boards and light steel joists - it drives quickly into the gypsum board and self-taps into the joist when encountered, without getting stuck or slipping.

Product Feature

Self-tapping sharp-tailed screws eliminate the need for pre-drilling: With the sharp tail, the electric screwdriver can directly drive the screw after alignment. There's no need to drill a small hole first, nor to change the drill bit and then the screwdriver bit. This saves one process, allowing decorators to drive hundreds more screws in a day.

Deep cross slot, no slipping of the screwdriver head: The depth of the cross slot is sufficient, ensuring a stable insertion of the screwdriver head. The decoration worker uses an electric screwdriver all day long, yet the slot opening remains round and smooth. Cross slot screwdriver heads are widely available, making replacement easy and convenient.
