Forgefix TechFast Timber to Steel CSK/Wing Screws are used to join timber to steel frame buildings. The screws are fitted with breakaway wings that create a clearance hole to protect thread from engaging timber when drilling through. Breakaway wings will ream a hole, then break-off when they contact the metal surface to be drilled. The thread will then engage with metal. They have a TORX® compatible insert for a higher transmission of power. With improved countersinking from recessed ribs.

Fire and corrosion resistant. Complies with EU Safety, Health and Environmental requirements.
