Metallics QDS80 – Frequently Asked Questions
1) What driver do I need for the Metallics QDS80 tapping screw?
The QDS80 takes a 5/16 inch hex driver on the head, and the Quadrive head also accepts a hex, slotted, Phillips, or square drive. In practice a 5/16 nut driver or impact socket is the fastest way to run them, with a square or Phillips bit as the backup when you cannot get a socket onto the head.
2) What size and length is the Metallics QDS80 screw?
It is a #10 diameter screw, 2-1/2 inches long, with a sharp point for self-starting into wood and light metal. That length is what you reach for when you are fastening through strap, box mounting ears, or plywood into framing rather than sheet-to-sheet.
3) Is the QDS80 a self-drilling screw or a sharp point screw?
Sharp point, not self-drilling. The QDS80 taps its own thread as it drives, but it has no drill flute on the tip, so it is intended for wood, light-gauge steel, and similar substrates. For heavier gauge steel you want a self-drilling point instead.
4) Are these zinc plated screws OK for damp or outdoor electrical work?
The QDS80 is steel with zinc plating, which is a mild corrosion coating meant for dry interior service. For wet locations, exterior runs, or corrosive atmospheres, specify a stainless or heavier coated fastener rather than standard zinc plated steel.
5) How do I order the Metallics QDS80 and what part number should I quote?
Order it by Metallics part number QDS80. There is one configuration, the #10 by 2-1/2 inch 5/16 hex head sharp point tapping screw in zinc plated steel, so there is no finish, drive, or length option to specify beyond that number.
6) Where are Metallics QDS80 screws made?
Made in the USA. That matters on public and institutional jobs where domestic sourcing is a condition of the contract.
