Metallics JQK16GR – Frequently Asked Questions

1) Can the Metallics JQK16GR self-piercing screw be driven without drilling a pilot hole?
Yes. The JQK16GR is a sharp point self-piercing and tapping screw, so it pierces thin sheet metal and cuts its own thread as it drives. Twin lead threads cut driving torque, and the undercut under the head gives you more thread engagement once it seats.
2) What driver do I need for the JQK16GR screw, a hex socket or a flat blade?
Either one works. The head is a 1/4 inch hex with a slotted drive across the top, so you can run it with a 1/4 inch hex driver in a drill or back it out with a flat blade screwdriver. Head width measures 0.244 to 0.25 inch, slot width 0.045 to 0.054 inch and slot depth 0.052 to 0.074 inch.
3) Do the JQK16GR screws meet Buy American or ARRA requirements on a public project?
Metallics lists the JQK16GR as compliant for both Buy American and ARRA purposes. Country of origin is China, so if your specification demands domestic melt and manufacture rather than compliance status, check the project language before you substitute.
4) Will a JQK16GR drop in for a standard #8 sheet metal tapping screw?
Not always flush with the same head footprint. Head dimensions on self-piercing screws differ from standard tapping screws, and there is no single dimensional standard for self-piercing heads, so the published figures are a guide and deviations occur. If the hole or counterbore was prepped for a standard #8 tapping screw head, confirm the 0.244 to 0.25 inch hex and 0.322 to 0.348 inch washer face clear it.
5) What size and thread count is the Metallics JQK16GR?
It is a #8 diameter screw, 1-1/4 inches long, with 15 threads per inch. That thread pitch and the sharp piercing point suit sheet metal work such as fastening to boxes, straps and light-gauge framing.
6) Is the JQK16GR screw hard enough to tap into steel, and will it rust?
Case hardness runs Rockwell C28-38 on AISI 1018 to 1022 steel, which is what lets the point pierce and thread sheet steel instead of stripping. The finish is zinc plated for general indoor corrosion resistance, with a gray head.
7) Does the JQK16GR come with a built-in washer under the head?
The head is formed with an integral washer face measuring 0.322 to 0.348 inch outside diameter and 0.019 to 0.031 inch thick. That spreads the clamp load on thin sheet so you don't need a separate washer for most sheet metal fastening.
8) How are these Metallics self-piercing screws packaged and what is the minimum order?
They ship in a jar of 100, and 100 count is the order minimum. Jar packaging keeps them together on a service van or in a shop drawer rather than loose in a bag.
