- Material / Coating: Galvanised coated fasteners have been used for roofing and cladding for over 150 years. Since galvanising was first introduced, we have seen a lot of new terms like Class 3, Class 4, B8, Climaseal 3, Climaseal 4, Climaseal 5, Armour Ceramic Coating, Mechanical Galvanised and Ruspert. They are all variations of the original galvanise. All self drilling and timber T17 screws from Bolt and Nut Australia are guaranteed to comply to a minimum of Class 4 and the ultimate of protection B8. Please refer to our technical pages for more information or contact us for advice on choosing the right fastener
- What does TPI stand for?: TPI stands for “threads per inch” which literally means the number of threads within each inch on a screw, a bolt, or a fastener. To determine the TPI of a screw, count the number of threads contained within an inch of length on the fastener. If the screw is less than an inch count ½” of an inch and multiply by 2
