The
Corroshield 12x25 (often designated as
12-14 x 25 mm) is a premium, high-performance
hex-head self-drilling roofing screw. Measuring
5.4mm in thread diameter (12 Gauge) and
25mm (1 inch) in length, it is engineered explicitly for high-corrosion industrial, coastal, and outdoor environments. It allows operators to drill, tap, and securely fasten metal-to-metal roofing cladding or steel purlins in a single action.
Anti-Corrosion Coatings (SDS-XYLAN / Ruspert / Zylon): Coated in multi-layered specialized polymer finishes. The Zinc-Aluminum alloy behaves as a sacrificial protection barrier against rust, moisture, UV, and salt spray. Bonded Weatherproof EPDM Washer: Equipped with a 2.5mm thick integrated round EPDM rubber washer. It compresses during installation to generate a long-lasting, watertight seal that prevents water leakage.
