Metallics QK17CCL – Frequently Asked Questions

1) Do I need to pre-drill a pilot hole for the Metallics QK17CCL self-piercing screw?
No. The QK17CCL is a sharp point self-piercing and tapping screw, so it pierces and forms its own thread in sheet metal as you drive it. Twin lead threads cut the driving torque, which helps when you are running a lot of them overhead or into studs by hand.
2) What driver do I need for the QK17CCL hex head screw?
It takes a 1/4 inch hex driver or nutsetter. The head is hex with a slot as a backup drive, so a flat blade works if you cannot get a nutsetter onto it. Head width runs 0.244 to 0.25 inch, slot width 0.045 to 0.054 inch and slot depth 0.052 to 0.074 inch.
3) Is there an integral washer under the head on these Metallics screws?
Yes, the head carries a washer section with an outside diameter of 0.322 to 0.348 inch and a thickness of 0.019 to 0.031 inch, so it seats against sheet metal or a strap without pulling through. There is also an undercut beneath the head that gives you more thread engagement in thin material.
4) How many QK17CCL screws come in a jar, and is there a minimum order?
They come packed in a jar of 250, and 250 count is the order minimum. Other sizes and quantities can be requested.
5) Will these zinc plated screws hold up in a damp or exterior electrical application?
The QK17CCL is carbon steel with a zinc plating, which is a mild indoor corrosion coating. It is fine for dry interior work such as boxes, straps, and raceway in conditioned space. For wet locations, exterior runs, or treated lumber contact, specify a stainless or hot dip galvanized fastener instead.
6) Do these Metallics screws meet Buy American and ARRA requirements for a public job?
Both the ARRA and Buy American compliance fields on the QK17CCL are flagged compliant, which is what a government, school, or healthcare procurement office needs to see on the submittal. Country of origin is listed as multiple.
7) Why don't the head dimensions on these self-piercing screws match a standard tapping screw?
Head dimensions on self-piercing screws differ from standard tapping screws, and there is no single industry standard governing them. The values given, including head height of 0.096 to 0.11 inch, are a guide and small deviations can occur. If you are matching an existing driver setup or a countersink, work from the ranges rather than a nominal tapping screw table.
8) What grade of steel are these screws made from and how hard are they?
AISI 1018 to 1022 carbon steel, case hardened to Rockwell C28-38. That is enough surface hardness for the point to pierce light gauge steel while the core stays ductile enough to resist snapping off in the hole.
9) How coarse is the thread on the #8 x 1-1/2 in. QK17CCL?
15 threads per inch on a #8 diameter, 1-1/2 inch long screw, with twin lead threads. That is a coarse pitch, which is what you want for sheet metal and for driving into wood framing without stripping.
