Metallics QTEKD14V – Frequently Asked Questions
1) What size and length is the Metallics QTEKD14V self-drilling screw?
The QTEKD14V is a #8 diameter screw, 1 inch long, with a 1/4 inch hex head and Quadrive drive recess. The hex head lets you run it with a 1/4 inch magnetic nut driver, and the Quadrive recess gives you a square-drive backup if you'd rather use a bit.
2) Do I need to pre-drill a pilot hole for these hex head screws into metal studs?
No. The QTEKD14V has a #2 drill point, so it drills its own hole and taps its own thread in one pass. That is what the self-drilling and tapping designation means: set the screw, run it, done. No pilot hole and no separate tap.
3) Are Metallics QTEKD14V screws made in the USA for Buy American jobs?
Yes. The QTEKD14V is made in the USA from domestic steel with a zinc finish. That matters on federally funded and institutional work where domestic-origin fasteners are called out on the submittal.
4) What thickness of metal will a #2 drill point screw go through?
The #2 point on the QTEKD14V is the light-gauge point, intended for sheet metal and light steel rather than structural stock. With a 1 inch overall length, the usable drilling and clamping range is limited to thin material plus whatever you are fastening to it. For heavier steel, step up to a #3 or #5 point screw in a longer length.
5) Are these screws coated for corrosion resistance, and can I use them outdoors?
Material is domestic steel with a zinc finish. Zinc plating handles interior and dry service well, including metal stud framing, strut, and enclosure work. For sustained outdoor exposure or damp locations, a zinc-plated carbon steel screw is not the right choice; specify a stainless or a coated exterior-rated fastener instead.
6) What driver do I need to install 1/4 inch hex head Quadrive screws?
A 1/4 inch magnetic hex nut setter in a drill or impact driver is the normal way to run these. The Quadrive recess in the top of the head is a second option if the hex gets chewed or you are working in a spot where a nut setter will not seat. No specialty bit needed either way.
7) Will a hex washer head screw like this hold strap, clip, and plate without pulling through?
The 1/4 inch hex head gives a broader bearing surface than a pan or trim head, so it seats flat against straps, clips, channel, and box flanges without pulling through sheet material. It does not countersink, so it is not the screw to use where you need a flush surface.
8) What is the Metallics part number to reorder these screws?
Order by Metallics part number QTEKD14V. That designation covers the #8 x 1 inch, 1/4 hex head Quadrive self-drilling and tapping screw with the #2 drill point in domestic steel zinc.
