ForgeFix TechFast Timber to Steel CSK/Wing Screws 5.5x150mm (Box 50)

The ForgeFix TechFast Timber to Steel CSK/Wing Screws are specially designed for joining timber to steel frame buildings. These innovative screws feature breakaway wings that create a clearance hole to protect the threaded portion from engaging with the timber during drilling. Once the wings make contact with the metal surface, they snap off, allowing the thread to engage securely with the metal. The screws are equipped with a TORX® compatible insert for superior power transmission and torque control. Additionally, they offer improved countersinking thanks to recessed ribs.

Engineered for durability, these screws are both fire and corrosion-resistant, ensuring long-lasting performance even in demanding conditions. They comply with strict EU Safety, Health, and Environmental requirements, making them a reliable choice for construction applications.
