- Villaboard Screws are self embedding and designed for fixing fibre cement sheeting to thin gauge steel substrates (up to 0.75mm thick) and timber framing. The ribbed underside of the head allows the screw to easily countersink without mushrooming the fibre cement sheeting. Needle point tip eliminates the need for pre-drilling, saving time during install. Ideal for fixing fibre cement or villa board sheeting to thin steel substrates whilst ensuring a flush finish.
- 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 self drilling and timber 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
- How to measure the length of a Timber 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
- Thread Length: 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
