Product Information

Masonry screws (also called concrete screws) are self-tapping screws that are perfect for fixing materials directly into stone, masonry, and concrete without needing wall plugs. They have deep, wide threads, ensuring a secure fit once installed. Often used to fix timber, uPVC frames, pipes, and cable housing into masonry. The type of screw heads available for masonry screws include countersunk, double self-countersunk, flange, flat, pan, raised, and wafer. Coach screws: these are driven into materials using a spanner through a square or hexagonal head. They provide robust and heavy-duty fixing. Point: the end of the screw that’s first driven into the material when a rotational force is applied. Self-tapping screws are screws that create their own thread as they are driven into a material, ensuring a strong, tight fit. They are best used in soft materials such as softwoods and plastic. A pilot hole that’s slightly smaller in diameter needs to be pre-drilled before fitting.

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. When choosing the thread, consider the density of the wood. It’s best to use fine threads for hardwoods and coarse threads for softwoods.With that subterfuge having resulted in the death of another inmate, Toby, she was now plagued with remorse (and also understandably worried about her involvement becoming public knowledge). 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. Before buying screws, consider the type of project you need them for. Although some are designed for multipurpose use, others are more specialised and are designed for specific applications. Using the right type for the job will ensure they can take the load and stay securely in place. For a good fixing into most wall materials use the special fat moulded wall plug, 2212. Cream in colour they blend with many wall finishes when viewed from the side.

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. 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.

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. 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. 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.
