Product Information

Self-tapping and drilling screws are available in steel, carbon steel, and stainless steel. Gauge sizes range from 3.5 to 6.3mm, and lengths range from 12 to 120mm. 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 using self-tapping screws, the chart below shows the suggested drill size that you should use to drill the pilot hole.

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 When choosing the thread, consider the density of the wood. It’s best to use fine threads for hardwoods and coarse threads for softwoods.Drywall screws are used to attach plasterboard to light steel, wooden studs, or metal partitions. They’re typically lighter and have deeper threads than other types, enabling them to grip plasterboard securely and a sharp point so pre-drilling isn’t required. Types of screw heads for drywall screws include bugle, wafer, and countersunk. A bugle head sits flush with the plasterboard’s surface, a wafer head sits above the surface, and a countersunk head sits below the surface. Self-tapping screws are used where an application requires regular maintenance and regular easy access. These screws are useful in situations where products must be assembled and disassembled, such as access panels or even furniture. What self-tapping fasteners are available? 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. Point: the end of the screw that’s first driven into the material when a rotational force is applied.Those listed above are the most popular types, but there are other more specialist and less popular screw types available, such as: Self-tapping screws are a type of fastener with a unique feature. They work by tapping their own threads in materials like plastic, wood, and metal. Self-tapping screws are split into two main categories, Thread-Forming and Thread-Cutting. The screws are similar in the job they do; however, they have two differences. One of the screws has a flat base, the other has a sharp point.
