- Chipboard Screws, ideal for all types of timber including Treated Pine are a coarse thread screws with a countersunk flat head and ribs under the head that self embed with the timber surface for a flush or countersunk finish. The screw provides maximum grip and minimum stripout into chipboard, MDF, other composite and soft timbers. It is recommended to drill a pilot hole into some hardwoods so if possible, test on an outcut as performance and outcome vary depending on the type of timber and age. We suggest to choose a screw long enough to provide approx. 20mm of thread embedment into the chipboard or wood being fastened to
- 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 T17 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
