Metallics QTEKD12 – Frequently Asked Questions

1) Do the Metallics QTEKD12 screws need a pilot hole drilled first?
No pilot hole needed. The QTEKD12 is a self-drilling, self-tapping screw with a #3 drill point, so it cuts its own hole and threads in one pass through sheet metal. The #3 point is the heavier of the common small-diameter points and is suited to thicker gauge steel than a #2.
2) Are Metallics QTEKD12 screws made in the USA for a Buy American job?
Yes. The QTEKD12 is made in the USA from domestic steel, then zinc plated, which is what a public or federally funded project asks for when domestic sourcing is written into the spec.
3) What driver do I need for a Quadrive 5/16 head self-drilling screw?
Two choices on the QTEKD12: it has a 5/16 inch hex washer head you can run with a 5/16 inch magnetic nut setter, and the head is also Quadrive, meaning it takes a square drive bit. Handy when you are working in a tight spot where a nut setter will not seat squarely.
4) Will a 3/4 inch long #10 self-drilling screw hold in sheet metal strut and electrical boxes?
At 3/4 inch overall length and #10 diameter, the QTEKD12 is sized for attaching into sheet metal and light structural steel, which is why it is stocked as an electrical fastener. The usable penetration is short, so it is meant for thin material and stacked sheet connections, not for driving through thick framing or multiple layers of plywood.
5) Are these Metallics screws rated for outdoor or damp locations?
The QTEKD12 is domestic steel with a zinc plating. Zinc plating is a corrosion-resistant coating for dry and protected interior work. For sustained outdoor exposure, wet locations, or coastal air, go to a stainless or a heavier coated fastener instead.
6) What is the Metallics part number for a #10 x 3/4 inch hex head self-drilling screw?
QTEKD12 is the Metallics number for the 10 x 3/4 inch screw with a 5/16 inch Quadrive head and a #3 drill point in domestic steel zinc. That is the full ordering designation, no suffix to add.
