  • WHAT ARE THE DIFFERENT TYPES OF FIXING SCREWS?
    What are fixing screws? Before exploring specific screws, it's important that we take note of the basics first. So, what is a fixing screw? Well, a fixing screw is a specific type of fixture that holds materials together and ensures they stay in a fixed position. Typically, these screws are used to secure installations to floors, ceilings and walls. From erecting a signpost to taking on a fencing project, you're likely to use fixing screws. Essentially, these screws maintain a connection between two structures, meaning that most construction projects that seek to join two structures would be unsuccessful without fixing screws. Fixings as a broader term actually encapsulate different kinds of instruments. Typically, fixings refer to screws, nails, nuts, bolts and special anchors. However, these fixings differ in terms of how they are secured. For example, a nail is usually hammered into a pre-drilled hole, a screw is twisted into a hole with a screwdriver whether it's pre-tapped or not, and nuts and bolts refer to a type of fastener which is used to secure screws and hold them in position for longer. Screws are pretty unique when it comes to their size, shape and head shapes. Depending on the type of fitting, screws may come with a cross-head type for a Phillips screwdriver or a single slot for a flat-blade tool.
