Metallics QTEKD2V 8 x 3/4 in. 1/4 Hex Head Quadrive Self-Drilling & Tapping Screws - #2 Drill Point - Domestic Steel Zinc - Each

No pilot hole needed. The QTEKD2V has a #2 drill point, so it drills and taps its own hole in one pass. The #2 point is the common choice for light to medium gauge sheet metal and steel studs, which is why these turn up on electrical rough-in work hanging strut, box brackets and plates.

A 1/4 inch hex driver seats the head. The QTEKD2V is a 1/4 hex head screw, so a 1/4 inch magnetic nut setter in a drill or impact is the fastest way to run them. The head also carries a Quadrive recess, which gives you a square-drive bit as a backup if you need to back one out in a tight spot where a nut setter won't fit.

Yes. The QTEKD2V is domestic steel and made in the USA, which is what public, government and institutional specs with domestic sourcing language are looking for on fasteners.

These are zinc plated domestic steel. Zinc plating handles interior and dry or occasionally damp conditions, but it is not a stainless screw. For exposed exterior, coastal or wet locations, specify a stainless self-drilling screw instead of the zinc QTEKD2V.

A self-drilling screw like the QTEKD2V carries a drill point on the tip, so it bores and threads the hole itself with no pre-drilling. A plain self-tapping sheet metal screw has a sharp or blunt point and still needs a pilot hole in anything but the thinnest stock. If your crew is fastening to steel studs or sheet metal all day, the drill point version saves the second pass.

Order Metallics QTEKD2V. That part number covers the #8 diameter by 3/4 inch length, 1/4 hex head with Quadrive recess, #2 drill point, zinc plated domestic steel configuration.
