Engineered for demanding roofing and cladding applications, this A2/A4 stainless passivated self-drilling screw combines high-grade materials with precision design to deliver maximum durability and reliability. Manufactured from corrosion-resistant stainless steel and treated through a passivation process, the screw offers superior resistance against rust, oxidation, and harsh environmental exposure, making it ideal for coastal, industrial, and high-moisture environments.
The integrated EPDM washer ensures watertight sealing by compressing evenly under load, effectively preventing leaks and moisture ingress around the fastening point. Unlike standard washers, EPDM rubber maintains its elasticity and sealing properties over time, providing consistent waterproof performance even in extreme temperatures or UV exposure.
Designed with a sharp self-drilling point, the screw eliminates the need for pre-drilling, ensuring faster, cleaner installation while reducing labor time. Deep, precision-cut threads deliver outstanding grip in both metal and wood substrates, keeping panels securely fastened and minimizing the risk of loosening under wind or vibration.
The sleek stainless steel finish, combined with its structural strength and weatherproof sealing, makes this screw a top choice for roofing professionals and contractors seeking long-term performance without compromising aesthetics.
