Metallics QTEKD8 – Frequently Asked Questions

1) What size screw is the Metallics QTEKD8, and what drive and head does it take?
The QTEKD8 is a #12 diameter self-drilling, self-tapping screw 1 inch long, with a 5/16 inch hex-style head and Quadrive drive. Driver choice matters on the job: the 5/16 head takes a 5/16 nut setter, and the Quadrive recess lets you drive the same screw with a bit when a socket will not clear.
2) Will a #3 drill point self-drilling screw go through steel studs or heavier channel?
The QTEKD8 carries a #3 drill point, which is the heavier point used for thicker steel than the #1 and #2 points found on light-gauge sheet metal screws. It drills its own hole, so no pilot is needed, and it taps its own thread as it goes.
3) Are the Metallics QTEKD8 screws made in the USA?
Yes. The QTEKD8 is domestic product, made in the USA, which is what lets it clear Buy American and domestic-content requirements on federal and institutional electrical work. The material is domestic steel with a zinc finish.
4) Is a zinc plated screw okay for outdoor or damp locations?
Zinc plating on the QTEKD8 is a general-purpose indoor and dry-location coating. For sustained exterior exposure, wet locations, or treated lumber contact, specify a stainless or heavier coated self-drilling screw instead; zinc plated steel will corrode in those conditions.
5) Do I need to drill a pilot hole before driving the QTEKD8?
No pilot hole. The drill point on the QTEKD8 cuts the hole and the screw threads tap it in the same operation, so it goes in with one driver and one pass. Run it at a lower speed with steady pressure so the point cuts rather than work-hardens the steel.
6) What is the Metallics QTEKD8 typically used for on electrical jobs?
It is an electrical-trade fastener, used for hanging strut, straps, boxes, and enclosures to steel where you want to drill and tap in one pass. The 1 inch length suits attaching hardware through a bracket or flange into steel rather than long standoff work.
