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.
These light section roofing screws are suitable for fixing timber to steel thicknesses of 1.5mm to 4mm. Each pack is supplied with a free Torx bit.
