Metallics QDS172 – Frequently Asked Questions

1) What size screw is the Metallics QDS172, and how long is it?
The QDS172 is a #12 diameter sharp point tapping screw, 1-1/4 inches long, with a 5/16 inch hex head. That length gives you enough bite to pull two layers of sheet metal or light gauge framing together without punching through drywall on the back side.
2) Can I drive the Metallics QDS172 with a nut driver, or do I need a screwdriver bit?
Either works. The head is a 5/16 inch hex, so a 5/16 nut driver or impact socket seats on it directly, and the Quadrive top takes hex, slotted, Phillips, or square drive. Handy when you are up a ladder with one tool and no time to go back down for another.
3) Do I need to pre-drill for these sharp point tapping screws?
No. The QDS172 is a sharp point tapping screw, so it pierces and forms its own thread in sheet metal, light gauge stud, and wood without a pilot hole. If you are going into heavy gauge steel or structural plate, that is a job for a self-drilling point instead.
4) Is the Metallics QDS172 OK to use outdoors or in a damp mechanical room?
It is zinc plated steel, which handles indoor and normally dry conditions and gives some protection in occasional damp. For direct weather exposure, coastal air, or anywhere it will sit wet, zinc plating will eventually rust through and you want stainless instead.
5) What are these hex head tapping screws typically used for on electrical work?
Mounting work. A #12 by 1-1/4 inch hex head tapper is the usual fastener for hanging strut, box supports, panel and enclosure backs, and raceway brackets to sheet metal or light framing. The 5/16 hex head lets you run them fast with a driver and gives a wide bearing surface so the head does not pull through a thin bracket.
6) Are Metallics QDS172 screws made in the USA?
Yes, the QDS172 tapping screw is US made, which is what you need when a public or institutional job carries a domestic sourcing requirement on fasteners.
