Screws

FAQs

What are the main screw types?

The main types of screw include wood screws, designed for fastening wood, machine screws used with nuts or tapped holes in metal, and self-tapping screws that create their own threads in softer materials like plastic or thin metal. Other common types are sheet metal screws for metal-to-metal fastening and concrete screws, ideal for masonry. Screws also vary by head types such as flathead, round head, or pan head. Whatever type of screw you need, you'll find a great range here at YESSS, including options in various lengths and diameters to suit your needs.

How do I know if I need a machine screw or a wood screw?

This depends on the kind of material you are working with. For example, machine screws are designed for use with pre-threaded holes in metal or other rigid materials and are often secured with nuts or bolts. Wood screws are designed to fasten into wood, featuring a pointed tip and a coarse thread for better grip.

Can extension screws be used in masonry?

Extension screws are not typically suitable for masonry unless used in conjunction with anchors designed for masonry. The anchors provide the necessary grip and stability in the material, as screws alone cannot hold well in masonry. For applications requiring superior performance in masonry, consider screws with corrosion resistance for outdoor use.

How do I choose the right screw cap or cover for my project?

To choose the right screw cap or cover for your project, consider the screw head size, shape, and colour. Check the cap or cover fits snugly and complements the material or design for a perfect finish. Additionally, ensure the cover matches the drive type of the screw for proper alignment.

What is the difference between a panhead screw and a plate screw?

A panhead screw has a rounded, flat head that sits above the surface and is popular for general use. A plate screw is specifically designed to secure plates or flat components, often with a flatter head profile to sit flush or slightly recessed. Both are available in various fasteners options to suit different materials.

What is a self-tapping screw?

A self-tapping screw is a type of screw that creates its own thread as it is driven into a material, typically used with softer metals or plastics. It eliminates the need for pre-tapped holes and is useful for speeding up projects. For certain applications, twin thread screws can provide enhanced grip and stability compared to single-thread designs.
