Metallics QTEKD14 – Frequently Asked Questions
1) Do I need to pre-drill a pilot hole for the Metallics QTEKD14 self-drilling screw?
No pilot hole needed. The QTEKD14 has a #2 drill point, which cuts its own hole as you drive it into steel. That is the whole point of a self-drilling and tapping screw: the point drills, then the threads tap, in one pass.
2) Are Metallics QTEKD14 screws made in the USA for Buy American jobs?
Yes. The QTEKD14 is domestic steel and made in the USA, which is what procurement on federally funded or Buy American specified work usually needs to see on the submittal.
3) Will a #2 drill point screw go through heavy structural steel?
No. A #2 point is built for light to medium gauge metal, not structural thickness. If you are fastening into heavy plate or thick beam flange, you need a higher numbered drill point with a longer flute, or a pre-drilled and tapped hole. The QTEKD14's 1 inch length also limits how much material it can pass through and still engage.
4) What driver do I need for the Metallics QTEKD14 hex head screw?
A 1/4 inch hex nut driver or socket handles it, and the head also carries a Quadrive recess so a square/Phillips-style bit works when you cannot get a nut setter into a tight spot. Useful when you are running screws behind a strut channel or inside a panel.
5) What size is the Metallics QTEKD14 screw?
It is a #8 diameter screw, 1 inch long. That length suits fastening through sheet metal into light gauge steel where you need a short, self-drilling fastener, common on electrical boxes, brackets, and duct or panel work.
6) Are the Metallics QTEKD14 screws zinc plated, and can I use them outdoors?
The QTEKD14 is domestic steel with a zinc finish. Zinc plating is a general corrosion coating suited to interior and protected applications. For direct exposure to weather or coastal conditions, choose a stainless or coated exterior-rated self-drilling screw instead.
7) What is the part number to order for the 8 x 1 inch hex head self-drilling screw from Metallics?
Order Metallics QTEKD14. That covers the #8 x 1 inch, 1/4 inch hex head, Quadrive, #2 drill point screw in zinc plated domestic steel.
