Key Features and Functions:
Unmatched Drilling Power: Equipped with a No.5 drill tip, these screws effortlessly drill through heavy gauge steel up to 12.5mm, making them ideal for the most demanding construction projects.
Advanced Coating Technology: Each screw is treated with the RUSPERT silver coating, a multi-layered, corrosion-resistant chemical formula that ensures they withstand over 1000 hours of salt spray testing, providing exceptional durability and protection against the elements.
Secure Sealing: The inclusion of a 16mm EPDM rubber washer guarantees a watertight seal, protecting your structures from moisture damage and enhancing the overall integrity of your builds.
Rigorous Safety Standards: Our screws comply with stringent EU Safety, Health, and Environmental requirements, ensuring they meet the highest industry standards.
Application Scenarios:
