Metallics JQK17 – Frequently Asked Questions

1) Do I need to pre-drill a pilot hole for the Metallics JQK17 self-piercing screw?
No pilot hole needed in sheet metal. The JQK17 is a sharp point self-piercing and tapping screw, so it pierces and forms its own thread as you drive it. Twin lead threads cut the driving torque, and the hardness runs Rockwell C28-38 so the point holds up while it works through the metal.
2) What driver do I need for the JQK17 hex head screw?
A 1/4 inch hex driver or nutsetter. The head measures 0.244 to 0.25 in. across and stands 0.096 to 0.11 in. high. There is also a slot on top (0.045 to 0.054 in. wide, 0.052 to 0.074 in. deep), so a flat blade works in tight spots where a nutsetter will not reach.
3) Do Metallics JQK17 screws meet Buy American or ARRA requirements for a federal project?
No. The JQK17 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing clause, this part will not satisfy it.
4) Does the JQK17 screw have an integral washer, and how much does it cover?
Yes, it has a washer face 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 spreads the bearing load on thin sheet, but it will not bridge an oversized or torn hole, so you still want the point starting in solid metal.
5) What is the thread count on the Metallics JQK17 #8 screw?
15 threads per inch on a #8 diameter, 1-1/2 inch long screw. The undercut area beneath the head gives you more usable thread engagement than a standard tapping screw of the same nominal length.
6) Will these screws rust if I use them in a damp mechanical room?
The JQK17 is zinc plated carbon steel, made from AISI 1018 to 1022 steel. Zinc plating handles normal indoor and mechanical room conditions. For direct exposure to weather, salt air, or standing moisture, step up to a stainless or coated exterior fastener instead.
7) How are the Metallics JQK17 screws packaged and what is the minimum order?
They ship in a jar of 100 pieces, and 100 is the minimum order quantity. Metallics notes other sizes and quantities are available by request.
8) What are these self-piercing screws normally used for on the job?
Electrical, plumbing, heating and air conditioning work. Typical use is fastening into sheet metal: duct, boxes, straps, hangers and brackets where you want to drive without drilling first. The 1-1/2 inch length gives you reach through insulation or stacked material to the metal behind.
9) Can I match self-piercing screw head dimensions to a standard tapping screw I already have?
Not reliably. Metallics states head dimensions on self-piercing screws differ from standard tapping screws, and there is no single industry standard for self-piercing screw dimensions, so the published figures are a guide and deviations can occur. If a cover plate or clip depends on an exact head size, test one before committing the run.
10) How much does a jar of 100 JQK17 screws weigh and how big is the container?
About 0.71 lbs for the jar of 100, in a container measuring 3 x 2.7 x 3 in. Light enough to drop several part sizes into one van bin without eating payload.
