Metallics JDS178SS – Frequently Asked Questions

1) Do the JDS178SS screws need a pilot hole, or will they drill their own?
These are Type A tapping screws with a gimlet (sharp) point. The point starts in sheet metal and forms its own thread, but it is not a self-drilling screw, so there is no cutting tip to make the hole in heavier stock. In thin sheet the sharp point will pierce and tap; in thicker material drill a pilot first. Thread pitch is 10 threads per inch to the ASME B18.6.4 thread standard, which is what sizes the pilot.
2) Are these stainless screws safe to use on aluminum or galvanized steel?
Watch for galvanic corrosion. The JDS178SS is 18-8 stainless, and fastening stainless parts to aluminum or steel can set up a galvanic couple in some environments, which attacks the softer base metal around the screw. Indoors and dry it is usually a non-issue; in wet, coastal, or chemically exposed locations, isolate the joint or use a fastener matched to the base metal.
3) What driver do I need for the Metallics JDS178SS tapping screws, and can I run them with a drill?
The JDS178SS has an indented hex washer head with a slot, so it takes either a 3/8 inch hex driver or a flat blade. The head measures 0.367 to 0.375 inch across the flats and 0.409 across the corners, so a 3/8 nut setter seats it. The slot is 0.064 to 0.075 inch wide and 0.083 to 0.101 inch deep, which is there for hand finishing or backing a screw out when the hex is fouled. Most installers run the hex with a nut setter in a drill and keep the slot as a backup.
4) How thick a material will a 14 x 1-1/2 in. tapping screw hold in?
The JDS178SS is a #14 diameter screw at 1-1/2 inch length, so you get usable thread engagement through a stack well over an inch thick before the point runs out. Allow for the head height of 0.172 to 0.19 inch sitting above the surface, plus the integral washer face (0.480 to 0.520 inch outside diameter, 0.030 to 0.050 inch thick) that spreads the clamp load. For thin sheet only a few threads engage, which is normal for Type A, so the holding power comes from the sheet, not the screw.
5) How are the JDS178SS screws packaged and what is the minimum I can order?
They ship in a jar, with an order minimum of 100 count. Total package weight is 2.22 lbs. Typical use is a jar on the truck for strut, sheet metal enclosures, and box mounting work.
6) Do these screws meet Buy American and ARRA requirements for a federal job?
Metallics lists the JDS178SS as compliant for both Buy American and ARRA. Country of origin is recorded as multiple, so if your submittal requires a single named origin per lot, that is worth confirming against the shipped lot.
7) What dimensional standard do these indented hex head tapping screws conform to?
Head dimensions follow ASME B18.6.3-2010 and the threads follow ASME B18.6.4. That matters on a spec job where the submittal calls out a standard rather than a part number. One exception Metallics notes: dimensions for #9 diameter screws in this family are independent of ASME B18.6.4. The JDS178SS is a #14, so it is within the standard.
8) Can I get this screw in a different length or a bigger quantity?
The JDS series indented hex head slotted tapping screws run in other diameters and lengths, and other pack quantities, available by request. The JDS178SS specifically is the #14 x 1-1/2 inch 18-8 stainless version with the 3/8 hex head.
