Metallics JDS158SS – Frequently Asked Questions

1) Will the Metallics JDS158SS tapping screw work in sheet metal without pre-drilling?
The JDS158SS is a Type A tapping screw with a gimlet (sharp) point, so it forms its own thread in thin sheet metal, and in light gauge work it can start in a punched or pre-pilot hole. Type A is the sheet metal thread form, 12 threads per inch at a #10 diameter, 1 inch long. For thicker steel or structural sections you want a Type B or self-drilling screw instead, not a Type A.
2) Are stainless tapping screws OK to use on aluminum or galvanized steel enclosures?
Be careful. These are 18-8 stainless, and fastening stainless parts to aluminum or steel can set up a galvanic couple that corrodes the softer metal in some environments, especially outdoors or anywhere wet or salty. For a dry indoor enclosure it is a non-issue in practice. On exterior aluminum, isolate the joint or use a fastener that matches the base metal.
3) Does the JDS158SS have a built-in washer face under the head?
Yes, the indented hex head carries an integral washer with a 0.384 to 0.414 inch outside diameter and 0.019 to 0.031 inch thickness. That spread of bearing surface is why these are the common choice for strut, box covers, and straps, and it means you do not need to add a separate flat washer. Head height runs 0.105 to 0.12 inch.
4) Do these stainless screws meet Buy American requirements for a federal or institutional job?
The JDS158SS is flagged compliant for both ARRA and Buy American, which is what a government, school, or healthcare procurement file usually needs on a fastener line item. Country of origin is listed as multiple, so if your spec demands a single named origin, that is the point to settle before you submit.
5) What standards do Metallics JDS tapping screws conform to?
Head and drive dimensions follow ASME B18.6.3-2010, and the thread follows ASME B18.6.4, the tapping screw standard. Hardness is Rockwell C28-38. One caveat worth knowing across the JDS series: dimensions for #9 diameter screws fall outside ASME B18.6.4. The JDS158SS itself is a #10 diameter.
6) Is a 1 inch long #10 tapping screw too long for fastening a cover to a sheet metal box?
At 1 inch of length under the head, the JDS158SS leaves a lot of thread past thin sheet, so plan for the protrusion inside the enclosure or where it could hit a conductor. It suits strap, clip, and bracket work where you need thread engagement through a stack. For a flush cover on single-thickness sheet, a shorter #10 Type A in the same indented hex slotted style is the cleaner call.
