Metallics QDS185V – Frequently Asked Questions
1) What size screw is the Metallics QDS185V, and what drive does it take?
The QDS185V is a #10 diameter, 2 inch long sharp point tapping screw with a 5/16 inch hex head. The head is a Quadrive type, meaning it accepts hex, slotted, Phillips and square drivers, so a 5/16 nut driver on a drill is the fast route but a Phillips or square bit will turn it if that is what is in your pouch.
2) Will a sharp point tapping screw like the QDS185V bite into wood and thin steel, or do I need a self-drilling point?
Sharp point is the key detail here. The QDS185V has a sharp point rather than a drill point, so it starts on its own in wood, plastic and thin sheet steel but it will not cut its own hole in heavier gauge metal. For structural steel or thicker channel you want a self-drilling (TEK-style) point or a pre-drilled pilot hole.
3) Are these screws zinc plated for damp or outdoor use?
The QDS185V is steel with a zinc finish. Zinc plating handles indoor and sheltered conditions and resists incidental moisture, but it is not a marine or sustained-exterior coating; for wet exterior or coastal work use a stainless or hot dip galvanized fastener instead.
4) Are Metallics QDS185V screws made in the USA?
Yes. The QDS185V hex head tapping screw is manufactured in the USA, which matters on public and institutional jobs carrying domestic sourcing requirements.
5) Do I need a washer or anything else with these hex head screws?
Nothing is included beyond the screws themselves. The 5/16 hex head is unwashered, so if you are fastening through slotted strut, sheet metal brackets or soft material and want bearing area, add a separate flat or sealing washer. No anchors come with it either, so masonry work needs a separate anchor system.
