Timco Composite Panel Hex Head Self-Drilling Screw 5.5/6.3 x 150 mm, 100 pcs

Overview

The Timco Composite Panel Hex Head Self‑Drilling Screw provides a premium, time‑saving fastening solution for attaching composite panels to light‑section steel. Its hardened carbon‑steel case and core give exceptional durability and shear resistance, while the self‑drilling point (No.3 type) penetrates steel up to 5 mm without pre‑drilling.

Key Features

• Fixed washer – 12 mm diameter for a wide bearing surface that prevents the head pulling through the panel and ensures a watertight finish.
• Split‑thread design – delivers superior grip and pull‑out resistance, creating a vibration‑resistant joint.
• Hexagon head – fits an 8 mm socket for high‑torque application with standard power tools.
• Silver organic finish – corrosion‑resistant, tested to 500 hours of salt‑spray exposure, ideal for exterior use.
