White wafer head self-drilling screws are commonly used in a range of applications, particularly in metal roofing and siding installations. Their ability to create a secure and weather-tight seal makes them ideal for exterior applications where moisture ingress could lead to structural damage. Additionally, they are often employed in HVAC (heating, ventilation, and air conditioning) installations, where metal framing and ductwork require reliable fastening solutions.

In addition to their resistance to corrosion, galvanised hex head bolts are also known for their strength and durability. The hex head design of these bolts makes them easy to tighten with a wrench, providing a secure and stable connection between materials. This is especially important in construction projects where the structural integrity of the building or structure is crucial.
