Screws to Wood With a 19mm Bonded Washer (Pack of 100)
When fixing roofing or cladding sheets to timber purlins, these TEK self‑drilling screws provide a secure, water‑tight solution. Featuring a 5/16″ hex head and a 19mm bonded sealing washer, they help deliver a reliable and professional finish. We recommend using 32mm screws for box profile sheets, while 45mm screws are better suited to tile form sheets.
