Description

Series 500 Wafer Head Self Drilling Screws have an extended drill point for drilling through steel up to 12mm by creating a hole. Commonly used for cladding and metal roofing, carports, sheds, garages and general construction when you need to drill into thicker than normal steel.
Installation: Install using a PH3 phillips driver bit in a cordless drill driver at a MAX speed of 2500 rpm. Whilst we know in most instances using an IMPACT driver does work it is recommended NOT to use an IMPACT driver due to the power, speed and drilling nature and action of an Impact drill.
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 measure ½” of an inch and multiply the number you counted 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:Extended (no.5) series 500 point is designed for drilling through steel up to 12mm thick
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
Dimensions: Our stock is sourced from various suppliers, therefore differences may exist between batches such as height, length, width, head style, visible stamped markings, appearance or actual finish
Photos: are of the product but may not be the actual diameter, length, thread length, colour you require, always refer to the size in the description and additional specifications data provided prior to ordering
