Product Information

The advantage of self-tapping screws for aluminium is that they don't need pre-drilling and are easily removed without damaging the metal. They can also be reused in the same material. Self-drilling screws are available in the same head and drive types as self-tapping screws. You should select your screw type based on the material and finish you require. Below we have outlined some factors to consider when selecting. The difference between self-tapping and self-drilling fasteners is that self-tapping screws will tap a hole into a soft material, self-drilling screws can drill a hole into anything from metal to wood meaning no pilot hole is needed. You can find out more in our self-tapping screws guide. Thread-Forming Screw Coach screws: these are driven into materials using a spanner through a square or hexagonal head. They provide robust and heavy-duty fixing. Woodscrews are available in a range of materials such as carbon steel, hardened steel, zinc, stainless steel and solid brass. Brass is usually chosen for its appearance when combined with brass ironmongery such as hinges and door handles. Stainless steel is ideal for areas exposed to moisture, and carbon and hardened steel can be fitted without needing pre-drilled holes. In addition, all wood screw materials have high levels of corrosion resistance. They are available in gauge sizes ranging from 3 to 8mm and lengths from 12 to 300mm.

Consider the material you are screwing into. Self-tapping screws are suitable for fixing sheet metal to softwood or plastic, and self-drilling screws are best for sheet metal to steel.Those listed above are the most popular types, but there are other more specialist and less popular screw types available, such as: When choosing the thread, consider the density of the wood. It’s best to use fine threads for hardwoods and coarse threads for softwoods. Drill Point – The drill point refers to the unthreaded section of the screw. When selecting the screw length, you should account for the length of material you are drilling through. If the threads engage before the drill point length is completely through the material it will result in the screw breaking 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.

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. Masonry screws are available in zinc, carbon steel, hardened steel, and high tensile steel. They have an anti-corrosive coating and are tarnish-resistant, making them suitable for outdoor use. They’re available in gauge sizes ranging from 3 to 10mm and lengths ranging from 16 to 200mm. All that is required to insert a self tapper is a pilot hole to introduce the screw. They then form their own thread as the screw is driven into position. Once inserted, self tapping screws may be removed and re-used. SELF TAPPER SCREW

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.

To use self-tapping screws, place the screw directly on the aluminium sheet. The screw's sharp point will make its own hole. Stabilise the screw so it doesn't tilt as it is put in. Let the screw turn until it goes through. Take care not to over-tighten the screw as this can damage the metal or break the screw. Aluminium has many positive characteristics that make it easy to work with. When using self-tapping screws on aluminium, choose a self-tapping screw with a drill-like point and sharp cutting blade threads that extend down the whole length of the screw. These self-tapping screws are designed to keep thin metal from denting. This self-tapping screw does not require any preparation. As it has a pointed tip, it is not necessary to create a pre-drilled pilot hole. Thread-cutting screws can pierce a small entry hole while being driven into the material the thread is being created. Self tapping screws, usually referred to as self tappers, are screws for use when fastening to metal or plastic. 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.

As a screwdriver is the only real tool used when working with self-tappers, make sure that you have the screwdriver with the appropriate drive type.

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.When choosing the best self-tapper for your job, there are a few key points to consider e.g. the right head shape, drive type, and thread size are essential. Another factor would be the material the screws are used with, and the environment and elements they are exposed to. Grub screws: work using a pinning action that pushes two surfaces against each other, negating the need for a nut. They are often used in applications requiring a small, unobtrusive screw.
