These Forgefix TechFast Roofing Screws are designed for use in joining timber to steel and for light section purlins. They have a Torx, countersunk head to sit flush to the surface. The self-drilling point enables speedy insertion, and the wings create a clearance hole in the timber to eliminate the chance of ‘jacking’ when fixing.
The screws are zinc plated and have an ‘Elementech’ coating for superior anti-corrosion, which has been salt spray tested to 1,000 hours.
