- Pan Head Self Drilling Screws are a rounded head with a flat underside used in metal sheeting applications.
- Easy to install with a PH2 Phillips screwdriver or PH2 Phillips Driver Bit in a power tool.
- Material / Coating: Zinc Plated is the most common fastener of plating due to its the low cost and shiny bright silver finish. A thin layer of Zinc is applied by either electroplating or mechanically. The coating is intended to be used internally as it only offers an average level of protection against corrosion. If you want a fastener that will withstand the outdoor elements choose from our Stainless steel or Galvanised range
- 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
