For fixing timber to heavy section steel. Salt spray tested to 1,000 hours. Torx bit in each pack.
If you're joining timber to heavy section steel, these TechFast roofing screws will give you a strong and secure fix. The screws are fitted with breakaway wings to protect the thread from engaging timber while drilling through. The wings ream a hole, then break off when they come into contact with the metal surface being drilled - this engages the thread with the metal, and not the wood.
