Metallics JTEKDF18 – Frequently Asked Questions
1) Does the Metallics JTEKDF18 need a pilot hole drilled first?
No. It's a self-drilling screw with a #3 drill point, so the point cuts its own hole and taps the thread in one pass. That's what makes it quick for fastening strut, channel, or sheet metal boxes with a driver and no pre-drilling step.
2) Is the JTEKDF18 self-drilling screw okay for outdoor or damp locations?
The JTEKDF18 is zinc plated steel, which is a dry-location corrosion coating. It handles indoor electrical work, panel and box mounting, and sheltered areas fine. For exterior exposure, roof penetrations, or wet/corrosive locations, step up to a stainless or coated exterior-rated self-drilling screw instead.
3) What part number do I order for the Metallics #10 x 1-1/4 self-drilling flat head screw?
Order Metallics part number JTEKDF18. That one number covers the #10 x 1-1/4 Phillips flat head self-drilling screw with a #3 point in zinc plated steel, jar of 100.
4) What thickness of metal will a #3 point self-drilling screw go through?
A #3 drill point is the heavier of the common light-gauge points, meant for sheet steel and light structural stock rather than thin flashing. With a 1-1/4 inch length on the JTEKDF18, you've got enough shank to pass through a bracket plus the host metal and still get full thread engagement. For heavy plate, use a drilled and tapped fastener instead.
5) How many screws come in a jar of Metallics JTEKDF18?
100 screws per jar. The jar package is the one electricians usually keep on the truck or the bench, since it reseals and doesn't spill like a bagged count.
