Description

Countersunk Head Self Drilling Screws provide a flush or recess finish making then ideal for many applications, like mounting hinges or gate hardware. Will require countersinking.
Installation: Install using a PH2 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: Excellent grade for self-drillng screws due to its hardness. It is a magnetic stainless steel, hardened by heat treatment (which grades G304 and G316 cannot be). For this reason, it has excellent drilling properties – however G410 has lower corrosion resistance than G304 and G316 and should not be used in highly or even moderately corrosive environments or tea-staining will result
Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material
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
To determine Thread Length: Before buying countersunk screws, it is recommended to work out the overall length you need. Because the overall length includes head height and drill point length you have to add the 2 together then minus that from the overall length to get the approx thread length. For example: a 10g-16 x 40mm countersunk self drilling screw has a 4mm head height and a drill point of approx. 12.50mm equalling 16.50mm approx, so, on a 40mm screw you are going to be left with approx. 23.50mm of actual thread. This detail is often overlooked and it is only when the screws turn up you find they are too short and your project is delayed. All this data along with other specifications is on the specifications table and as always, measurements are approx and do vary between batches and suppliers, if critical always check with us prior
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
