Metallics JDS185 – Frequently Asked Questions

1) Will a #10 x 2 inch Type A tapping screw hold in sheet metal without pre-drilling?
Gimlet point, so it starts its own hole and forms its own thread in light gauge metal. That is the whole point of the Type A design on the Metallics JDS185: sharp point, 12 threads per inch, and it cuts as it drives. It is meant for light metal assembly such as electrical outlets, framing and other sheet metal work. For heavy structural steel you want a self-drilling point instead, not a gimlet point.
2) Can I use these screws on a Buy American or ARRA funded job?
No. The Metallics JDS185 tapping screw is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On federally funded work with domestic sourcing requirements you need a fastener that carries a domestic origin statement.
3) How much can I torque a #10 Type A tapping screw before it snaps?
48 lb-in is the minimum torsional strength on the JDS185, so treat that as your ceiling when setting an impact or clutch driver. The screw is hardened to Rockwell C28-38, which is what lets it form threads in light gauge without the point rolling over. Driving past the seat in thin metal will strip the formed thread long before the screw itself breaks.
4) Is a zinc plated tapping screw OK for outdoor or damp locations?
Zinc finish over AISI 1016-1024 carbon steel is a plated coating, not stainless. It handles indoor electrical and sheet metal work and incidental moisture fine. For sustained wet exposure, coastal air, or anywhere galvanic contact with dissimilar metal is a concern, a stainless or hot dip fastener is the better call.
5) Is 2 inches too long for fastening a device box to metal stud?
2 inches of fastener length gives you a lot of reach, which is what you want going through a box ear, a bracket, or a spacer into light gauge framing. On a straight sheet-to-sheet joint of two thin panels most of that length ends up projecting past the back side, so a shorter #10 is tidier there. Pick the length by total stack thickness plus a few threads of engagement.
6) What is the difference between a Type A tapping screw and a self-drilling TEK screw?
A Type A like the JDS185 has a gimlet point: it pierces and forms threads in thin material, but it needs the metal soft or light enough to punch through. A self-drilling screw has a drill flute point that bores a hole first, which is what you need in thicker gauge or doubled-up steel. For outlet boxes, register mounting, and general sheet metal, the Type A drives faster and cheaper. Once you are into heavier structural or stacked members, go self-drilling.
7) How many screws come in a jar of Metallics JDS185?
100 pieces per jar, and the jar is the minimum order unit. That is the pack a service van carries, not a bulk box, so if you are fastening out a whole floor of duct or strut, plan the count in jars.
8) Does the indented hex head on this Metallics screw take a sealing washer?
The head is sized for a washer with a 0.384 to 0.414 inch outside diameter and 0.019 to 0.031 inch thickness. The indented hex profile itself is a plain head, no bonded washer built in, so if you need a seal on duct or panel work you add the washer at install.
