Metallics JTTS21 – Frequently Asked Questions

1) What drivers fit the Metallics JTTS21 tri-drive tapping screw?
The JTTS21 has a tri-drive pan head, so it takes a slotted bit, a Phillips bit, or a square (Robertson) bit. That is useful on service calls where you are not carrying a full bit set, and it lets a crew back out screws driven by someone with a different driver.
2) What size screw is the Metallics JTTS21?
It is a #8 diameter by 1 inch long tapping screw. The 1 inch length suits anchoring boxes, straps, and plates to studs or sheet material where you want thread engagement without blowing through the back side.
3) Will a pan head screw sit flush, or do I need a flat head?
A pan head does not sit flush. The JTTS21 has a rounded pan head that seats on top of the surface, which is what you want for clamping down straps, box ears, cover plates, and clips. If the hardware is countersunk and the head has to finish level with the surface, use a flat head screw instead.
4) Are these zinc screws OK for outdoor or damp locations?
The JTTS21 is zinc plated steel, which is a dry indoor-duty finish. It handles normal interior conditions fine, but for exterior, wet, or corrosive environments you want stainless or a hot-dip galvanized fastener rather than zinc plate.
5) Do I need to pre-drill for these tapping screws?
These are tapping screws, so they cut their own thread into a pilot hole. In sheet metal and light steel you still drill a pilot sized to the screw's root diameter; in wood or plastic the #8 thread will usually pull in on its own. They are not self-drilling, so they will not start a hole in steel without one.
6) How are the Metallics JTTS21 screws packaged for a shop or van stock?
They come in a jar, which is how most electrical contractors want loose fasteners for the bench or the truck shelf. Easy to scoop from, easy to re-stock, no torn bags in the bottom of a bucket.
7) Are Metallics tri-drive tapping screws made in the USA?
Yes. The JTTS21 is manufactured in the USA, which matters on public and institutional jobs carrying domestic-content requirements.
