In the world of construction and engineering, corrosion resistance is paramount. That’s where DD Fasteners steps in with our latest innovation: Mechanical Galvanized Self-Drilling Screws. Designed to thrive in high-corrosion environments, these screws boast compliance with stringent standards such as ASTM B117, ASTM B695, DIN50018, DIN50021, and AS3566.2.

What sets our screws apart is their ability to endure rigorous testing. From Salt Spray tests lasting anywhere from 96 to an impressive 2000 hours, to Kesternich tests of 15 or 20 cycles, our screws consistently prove their mettle. The secret lies in our mechanical galvanization process, which provides a robust zinc coating, ensuring long-lasting corrosion resistance.

But it’s not just about durability. DD Fasteners’ screws are engineered for efficiency and reliability. With unparalleled drilling power and stability, they excel in a wide range of applications, from chemical plants to agricultural structures, from insulation projects to waterproof roofing. Our screws are meticulously crafted through a comprehensive in-house production process, guaranteeing quality at every step.
