2. Cost-Effectiveness The elimination of separate drilling reduces labor costs and the need for additional tools. This can lead to overall project savings, especially in large-scale applications where numerous fasteners are required.

1. Time Efficiency One of the most significant benefits of self-drilling screws is the reduction in assembly time. Since they do not require a pre-drilled hole, contractors and builders can work more quickly and efficiently. This is especially crucial in large-scale projects where time is of the essence.

- Decking These screws are perfect for decking projects, where strength and durability are essential. Their ability to withstand elements makes them ideal for outdoor structures that face moisture and temperature fluctuations.

- Signage and Fencing For outdoor projects, Tek screws are frequently employed to attach signs, fence panels, and other structures that need to withstand exposure to the elements.

2. Corrosion Resistance Many manufacturers provide M20 bolts with coatings or treatments (like galvanization) to enhance corrosion resistance. This is vital for outdoor and industrial applications where exposure to moisture and chemicals is common.
