Metallics QK15GR10M – Frequently Asked Questions

1) Does the Metallics QK15GR10M self-piercing screw come in small quantities, or is it a bulk box only?
Bulk only. The QK15GR10M ships as a box with an order minimum of 10,000 pieces, and the packed box weighs 54 lbs. If you need a few hundred for a single job, this is the wrong pack; Metallics offers other sizes and quantities by request.
2) Do self-piercing screws need a pilot hole in sheet metal?
No pilot hole. The sharp point pierces thin sheet as it drives, and the twin lead threads cut their own thread while reducing driving torque. Thread pitch is 15 threads per inch on a #8 diameter, 1 inch long screw. For heavier gauge steel you would move to a self-drilling point instead, since a sharp point relies on the material being thin enough to pierce.
3) Can I use these screws on a Buy American or ARRA funded project?
Metallics lists the QK15GR10M as both Buy American compliant and ARRA compliant. Country of origin is recorded as multiple, so if your specification requires a single named origin, confirm the origin on the box you receive.
4) Is this screw hard enough to tap its own thread, and what steel is it made from?
It is case hardened to Rockwell C28-38 and made from AISI 1018 to 1022 low carbon steel, which is what lets the sharp point pierce and the thread form in sheet material. Finish is zinc over steel.
5) Does the QK15GR10M have an integral washer head, and how much does it cover?
Yes, there is a washer under the hex head with an outside diameter of 0.322 to 0.348 in. and a thickness of 0.019 to 0.031 in. That spread gives you bearing surface over a pierced hole without a separate washer. There is also an undercut beneath the head, which gives you more usable thread engagement than a plain tapping screw of the same length.
6) Are self-piercing screw head dimensions the same as a standard tapping screw?
No. Metallics states plainly that head dimensions on self-piercing screws differ from standard tapping screws, and that there is no single industry standard for self-piercing screw dimensions. The published figures (0.244 to 0.25 in. across flats, 0.096 to 0.11 in. head height) are a guide and small deviations can occur. Worth knowing if you are matching an existing fastener for appearance or clearance under a cover.
7) Will a gray hex head screw blend in with painted trim or raceway?
The head is gray, which sits close to most mill-finish and gray-painted surface raceway, strut and sheet metal work. Underlying finish is zinc plated steel. If you need a color match to white or ivory devices, this is not it.
8) What is the exact part number to reorder these Metallics self-piercing screws?
Order Metallics part QK15GR10M, series JQK: a #8 x 1 in. sharp point self-piercing and tapping screw, 1/4 in. hex head with slotted drive, gray head, zinc plated steel.
