Tek screws are specially designed screws that feature a drill point at their tip. This drill point allows the screw to create its own hole as it is driven into the material, which is especially beneficial when working with thick steel. Unlike regular screws that require a pre-drilled pilot hole, Tek screws simplify the fastening process, saving both time and labor costs.

Metal expansion nuts find their usage in diverse fields. In construction, they are frequently employed for securing structural elements, like beams and frames, in concrete. They are also prevalent in HVAC systems, where they help secure ducts and other installations prone to thermal expansion.

Moreover, DIY enthusiasts use self-drilling screws in home repairs and renovations due to their user-friendly nature. Whether it's installing a shelf or building a garden shed, these screws are invaluable for ensuring a reliable and robust assembly.
