ManoMano

General description Forgefix TechFast Timber to Steel CSK/Wing Screws are specifically designed for joining timber to steel frame buildings. These screws feature breakaway wings that create a clearance hole during drilling, preventing the thread from engaging the timber and protecting it from damage. Once the wings contact the metal surface, they break off, allowing the screw to engage securely with the steel. Equipped with a TORX® compatible insert, these screws ensure higher torque transmission and improved countersinking with recessed ribs. They are also fire and corrosion resistant, protected by a durable coating that withstands salt spray testing.
