4. Corrosion Resistance The black phosphate coating not only provides a sleek finish but also protects the screws from rust and corrosion. This is crucial in regions with high humidity or in applications where moisture may be a concern, ensuring that the integrity of the assembly remains intact over time.

1. Self-Drilling Tek Screws These screws come with a drill point that allows them to penetrate and create their own pilot hole in concrete and masonry. They are ideal for fastening materials like metal, wood, or plastics to concrete surfaces.

Another advantage of self-drilling anchor screws is their resistance to corrosion and rust. This is particularly important for outdoor or humid environments, where traditional screws may degrade over time. By choosing self-drilling anchor screws made from corrosion-resistant materials, such as stainless steel, you can ensure that your installations remain secure and reliable for years to come.

In the construction and engineering fields, the strength and reliability of fasteners are critical. That’s why we are pleased to introduce new DIN6914/A325/A490 heavy-duty hex structural bolts to the market. This high-quality bolt is designed to provide superior strength and durability for heavy-duty applications on steel structures.
