Metallics JTSF59 – Frequently Asked Questions
1) What size are the Metallics JTSF59 screws, and how many come in a jar?
The JTSF59 is a #14 x 1 inch flat head Phillips self-tapping sheet metal screw in zinc plated steel, packed 100 to a jar. The jar pack is the form electrical contractors keep on the truck for panel, strap, and box mounting work rather than a loose bulk box.
2) Do these self-tapping screws need a pilot hole drilled first?
Yes. The JTSF59 is a thread-cutting sheet metal screw, not a self-drilling point, so it needs a pilot hole sized for a #14 thread. It cuts its own threads in the hole once started, which is why it holds in sheet steel without a nut.
3) Will a flat head screw sit flush, or will it stand proud of the surface?
Flat head means it seats flush when driven into a countersunk or dimpled hole. If the material is flat sheet with a plain drilled hole, the tapered head will pull down but still leave a slight crown, so countersink the hole where a flush face matters.
4) Are zinc plated screws OK for outdoor or damp locations?
Zinc plating on these #14 screws is a light corrosion coating meant for dry interior work, panel and enclosure fastening, and similar indoor electrical use. For exterior, wet, or corrosive locations, go with a stainless or hot dip galvanized fastener instead.
5) How thick a material will a 1 inch screw hold in?
The JTSF59 gives 1 inch of overall screw length measured from the top of the flat head down, since flat heads are measured overall rather than under the head. Subtract whatever the countersunk piece takes up to see how much thread is left engaging the substrate.
6) What driver do I need for the Metallics JTSF59?
Phillips. A #14 flat head in this size takes a #3 Phillips bit; a #2 will cam out and chew the recess under torque.
7) Is the Metallics JTSF59 ordered as a single jar or by the screw?
It is ordered as a jar of 100. One part number, JTSF59, covers the complete jar, so a quantity of one gets you 100 screws.
