Queensland Sheet Metal Screws / Fasteners Installation Guide
Fasteners are used to securely connect sheet metal flashings to wall claddings or other sheet metal. Fasteners are required for roofs, walls and a number of different applications on buildings. The specific number of fasteners you need will depend on the number of supports you are using, the type of metal you use, and the width of the sheet.
There are three common types of fasteners: timber fixing screws, metal and timber zips and self-drilling screws. When fixing metal roofing, all these types of screws will have washers on them that will hold your fastener in place, and provide a watertight seal.
