Ruwag Top Speed Screws Type 17 are used in conjunction with bonded washers for a water-tight seal on corrugated or IBR roof sheeting into soft or hard wood. The Type 17 cutting point makes a one-step installation process possible as no pre-drilling or pilot holes are required.
QUESTIONS & ANSWERSAsk a Question
I am using the 5.5mm top speed screws to fasten roof sheets onto a wooden frame. The only bonded washer I can find is a 6x19mm, is that hole size not to big?
Thank you for the enquiry
Our Type 17 Top Speed Screws have a flanged head to distribute force evenly and prevent pull through. Using the 6x19 bonded washer will be a perfect water tight installation and the hole size of the washer is ideal.
