Metallics JQK12114 – Frequently Asked Questions

1) Do I need to pre-drill a pilot hole for the Metallics JQK12114 self-piercing screw?
No pilot hole is needed in thin sheet metal. The JQK12114 is a sharp point self-piercing and tapping screw, so it pierces and forms its own thread as it drives. The twin lead threads cut driving torque, which helps when you are running a lot of them overhead in duct or box work.
2) Can I use Metallics JQK12114 screws on a federally funded job with Buy American requirements?
No. The JQK12114 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a job carrying domestic sourcing requirements you will need a fastener certified to those terms.
3) Does this Metallics screw have an integral washer under the head?
Yes, there is a washer face under the head with a 0.398 to 0.432 inch outside diameter and 0.022 to 0.039 inch thickness, which spreads the clamp load on sheet metal. There is also an undercut beneath the head so more of the shank length is available for thread engagement.
4) How coarse is the thread on a #12 x 1-1/4 self-piercing screw?
11 threads per inch on the #12 diameter, 1-1/4 inch long shank. That is a coarse twin lead thread meant to tap its own hole in sheet metal rather than thread into a tapped hole, so do not plan on it mating with a standard #12-24 machine screw nut.
5) Is the JQK12114 hard enough to pierce sheet steel without the point rolling over?
It is case hardened to Rockwell C28-38 and made from AISI 1018 to 1022 carbon steel, which is what lets the sharp point punch through sheet stock. That hardness is for sheet metal work, not for driving into structural plate or hardened material.
6) What trades actually use a #12 hex head self-piercing screw like this?
Metallics lists the JQK line for electrical, plumbing, heating and air conditioning work. Typical use is fastening to sheet metal where you cannot get behind the work to hold a nut, such as duct, strut accessories, boxes, and hangers. Note that self-piercing head dimensions differ from standard tapping screws, so if a spec calls out a standard tapping screw head this is not a straight swap.
7) Are these screws okay for damp or unconditioned areas like a mechanical room?
The JQK12114 is steel with a zinc plated finish, which handles indoor and unconditioned interior spaces. Zinc plating is not a marine or sustained outdoor exposure coating, so for exterior or wet locations step up to a stainless or hot dip galvanized fastener.
8) How are these Metallics self-piercing screws packaged and what is the minimum order?
They ship in a jar of 100, and 100 is the order minimum. Jar weight is 1.11 lbs. Metallics also offers other sizes and quantities in this line on request.
