Product Information

Consider what material the plasterboard will be attached to, as different screws are suitable for different materials. For example, there are drywall to heavy steel screws, drywall to light steel screws, and drywall to wood screws.

A huge selection is available for a wide range of applications. They can be classified by the type of material they’re made from, such as brass, stainless steel, carbon steel, etc., their size (diameter and length) and the different screw head types, drive types and thread types. Look for features such as shanks that reduce wood split, twin threads for a fast and accurate drive, and tips that don’t require pre-drilling. Coach screws: these are driven into materials using a spanner through a square or hexagonal head. They provide robust and heavy-duty fixing.If you are joining sheet metal to steel, choose self-drilling screws. But if you are joining sheet metal to wood, use timber roofing screws with a sharp point. Roofing screws are available in carbon steel and hardened steel. And, as they are most commonly used for outdoor applications, they have a coating that protects them from the elements and stops rusting. They’re available in gauge sizes ranging from 4 to 6.3mm and lengths ranging from 16 to 120mm.

When choosing masonry screws, consider the load it will bear, as different types are suitable for medium or heavy-duty loads. Timber screws are specially designed for use on timber. They have an aggressive, coarse thread that grips wood securely into place. They come in various gauges, head and drive types, and sizes, meaning there is a choice of screw for any task. Roofing screws are designed for attaching sheet metal to steel or wood as well as for other general exterior construction tasks. But they can also be used on internal jobs. The flanged (or washered) type of heads have a built-in washer that’s designed to reduce vibrations and stop the screws from loosening. And there are self-drilling and timber varieties available. When choosing the thread, consider the density of the timber. It’s best to use fine threads for hard timber and coarse threads for soft timber.Point: the end of the screw that’s first driven into the material when a rotational force is applied.
