• Efficient Self-Drilling No.3 Point: Pierces metal quickly and eliminates the need for pre-drilling, saving significant time on-site during installation.

• Weather-Tight EPDM Seal: The 16mm EPDM washer compresses upon installation to create a permanent, leak-proof barrier against the elements.

• Superior Corrosion Protection: Silver organic exterior finish provides an enhanced defense against rust in industrial and urban environments.

• Heavy-Duty Dual Thread: Specifically designed for composite panels to ensure maximum grip and stability within the core and outer skins.

• Professional Grade Carbon Steel: Hardened core construction provides the strength required for high-tension industrial cladding and roofing applications.

Description

These high-performance 5.5/6.3 x 150mm Metal Construction Composite Panel Screws are specifically engineered for fixing composite panels to steel sub-structures. Featuring a dual-thread design, these fasteners provide exceptional pull-out resistance and a secure fit for panels ranging from 100mm to 130mm in thickness. The integrated 16mm EPDM washer creates a weather-tight seal, preventing moisture ingress and ensuring long-term structural integrity in exterior applications.

Constructed from case and core hardened carbon steel, these self-drilling screws feature a No.3 drill point that pierces metal efficiently without the need for pre-drilling. The exterior silver organic finish provides a corrosion rating of 3, making them ideal for urban and industrial areas with low salt atmospheres. With a classic hex head for maximum drive engagement, these fasteners are the professional choice for large-scale industrial cladding, roofing, and cold storage construction projects where speed, reliability, and weatherproofing are essential.
