Aluminium Bonded Washer 50mm – Type 17 – Painted – Screw

Colorbond Painted Type 17 Screws with an aluminum bonded washer are specifically designed for fastening sheets to timber in wet and corrosive environments. The aluminum washer is compatible with Colorbond sheets and provides enhanced corrosion resistance, ensuring long-term durability in harsh conditions. The bonded washer effectively prevents leakage through fastener fixings, maintaining the integrity of the roofing or cladding system and preventing water infiltration. This feature makes these screws particularly suitable for use in areas prone to heavy rainfall or exposure to moisture.
