Metallics JDS171SS – Frequently Asked Questions

1) Will a #12 Type A tapping screw bite into sheet metal without a pilot hole?
The JDS171SS is a Type A tapping screw with a gimlet (sharp) point and 11 threads per inch, so it starts itself in thin sheet metal, duct, and sheet metal enclosures. Type A is a sheet metal screw thread, not a self-drilling screw, so it will not cut its own hole in heavy gauge steel. For thicker material, drill a pilot hole first.
2) Can I use these stainless screws to fasten into aluminum strut or steel boxes?
You can, but be aware of the metallurgy. 18-8 stainless fasteners in contact with aluminum or steel can set up a galvanic couple and corrode in some environments, particularly outdoors or anywhere damp or salty. Indoors and dry, it is a non-issue. If the connection is exposed, isolate the joint or use a fastener matched to the base metal.
3) Do these screws meet a dimensional standard I can put on a submittal?
Yes. The indented hex head conforms to ASME B18.6.3-2010 and the thread form to ASME B18.6.4. Hardness is Rockwell C28-38. Note that dimensions for #9 diameter screws in this family fall outside ASME B18.6.4, though that does not apply to this #12 size.
4) Are these screws Buy American and ARRA compliant for a government or institutional job?
The JDS171SS carries Buy American and ARRA compliance flags of C, with country of origin China. If your contract requires domestic melt and manufacture rather than ARRA-level compliance, check the flag against your specific clause.
5) Does the indented hex washer head need a separate washer?
No separate washer is needed. The head is an integral washer type with an outside diameter of 0.398 to 0.432 inch and a washer thickness of 0.022 to 0.039 inch, which spreads the clamp load over the sheet. Overall head height runs 0.139 to 0.155 inch.
6) What size and length is the Metallics JDS171SS?
It's a #12 diameter screw, 1 inch long, with a 5/16 inch indented hex head. The 1 inch length gives you grip through a layer of sheet metal plus insulation or a mounting flange; for thicker stack-ups you need a longer screw in the same JDS series.
