- Marine Applications Their corrosion resistance also makes brass self-drilling screws suitable for marine environments, where exposure to saltwater can be particularly damaging to traditional screws.

Additionally, these screws provide superior holding power compared to standard screws. Their design allows for deeper penetration and a tighter grip, making them less likely to loosen over time, especially in fluctuating temperatures and humidity levels. This stability is crucial in structural applications where safety and integrity are paramount.

2. Self-Drilling Capability With their sharp, pointed tips, galvanized Tek screws can effortlessly penetrate metal and wood, eliminating the need for additional drilling tools. This feature contributes to faster installation and reduces labor costs.

Heavy-duty expansion anchors are used in a wide array of applications, including
