Timco Composite Panel Hex Head Self-Drilling Screw - 5.5/6.3 x 180

The Timco Composite Panel Hex Head Self-Drilling Screw is a premium fastening solution specifically engineered for attaching composite panels to light section steel. Designed for efficiency and strength, this screw eliminates the need for pre-drilling, saving valuable time and effort on the job. Its robust construction features a hardened carbon steel case and core, ensuring exceptional durability and resistance to shear forces.

A key feature is the integrated fixed washer with a diameter of 12mm, which provides a wide, secure bearing surface. This helps to distribute load evenly and prevent the screw head from pulling through the panel material, ensuring a watertight and professional finish. The screw's specialised split thread design offers superior grip and pull-out resistance, creating a reliable, vibration-resistant connection that stands the test of time.

The self-drilling point (No.3 type) allows for quick and easy penetration of steel up to a maximum thickness of 5mm, making installation straightforward. The hexagon head is compatible with an 8mm socket, allowing for high-torque application with standard power tools. The exterior plating provides a durable, corrosion-resistant silver organic finish that withstands up to 500 hours of salt-spray testing, making these screws ideal for exterior applications where weather resistance is critical.

Supplied in a convenient box of 100 pieces, this product is perfect for roofing, cladding, and general construction projects. Whether you are a professional tradesperson or a dedicated DIY enthusiast, these screws offer a reliable, high-performance solution for securing composite materials to metal substrates with confidence and ease.
