- Painted Roofing Screws for fastening metal roof sheet to metal battens, steel purlins or other steel substrates. This screw is perfect in steel roof construction where a heavy duty roofing screw is required. The head is painted to match the corresponding colorbond colour.
- Top Grip: Top grip thread ensures a secure hold on sheeting, prevents dimpling and stops the roof sheet moving down the shank when the roof is walked on. The screw also come with upper shank protection the removes burrs that may damage the EPDM washer, and helps protect the galvanised coating on the upper thread
- Also known as:: XGP, High Grip, Double Grip, Crest Grip
- Installation: Easy to install using a 5/16” impact rated nutsetter or appropriate driver bit in a power tool, a large range available in the drilling driving tools section of our website.
- Material / Coating: Galvanised coated fasteners have been used for roofing, cladding, steel buildings, trailers, bridges, fencing, power poles, outdoor furniture, house framing, fencing and marina’s 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 metal self drilling screws from Bolt and Nut Australia are guaranteed to comply to a minimum of Class 3 and extend to 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
- Length of Thread: Always choose a self driller with enough threads to fully engage in the base metal. For attachments to 1/4" base steel, a self-drilling screw should have at least 1/4" of threads. It is helpful, but not critical, that the threads also engage in the material being fastened. The head of the fastener provides the bearing force for the material being fastened, while the threads provide the clamping force in the base material
- Thread Length: Thread lengths have been included as a guide only. Due to stock being sourced from multiple suppliers variations do exist. We will always ship the same brand and thread length but subsequent orders may be another brand and the thread length may be different. If thread length is critical, please message us prior to ordering as we are happy to physically check our stock and advise prior to shipping
- Drill Point Style: A twist drill style hardened point for fast driving into light gauge sheeting, cladding panels, sections and assemblies. The length of the drilling flutes determine the amount of drilling swaft that can be expelled and therefore the depth of metal can be drilled
- How to measure the length of a Metal Screw: Fastener length is generally measured from the point where the surface of the material will be when the fastener is installed to the end of the fastener. Thus, fasteners with heads that sit above the surface are measured from under the head to the end of the fastener, while fasteners that sit flush with the surface are measured from the top of the head to the end of the fastener
- Need a Driver Bit?: A large range of suitable driver bits are available in the "Driving" section of our website
- Measurements: Every effort has been made to ensure all measurements on our site are accurate and to the relevant standard, they should only be used as a guide. If you see a problem with our specifications please contact us
