Metallics JSTS26 – Frequently Asked Questions

1) Will #12 x 1/2 in. stainless tapping screws corrode if I drive them into aluminum strut or a steel enclosure?
They can. Metallics flags that fastening 18-8 stainless parts to aluminum or steel sets up a galvanic couple in some environments. On exterior, damp, or coastal work that matters; indoors in dry conditions it usually does not. If you are fastening to bare aluminum outdoors, isolate the joint or pick a fastener matched to the base metal.
2) Do I need to drill a pilot hole for a Metallics JSTS26 Type A tapping screw, or does it cut its own thread?
It is a Type A tapping screw with a gimlet point, so it forms its own thread in a pilot hole or in thin sheet. The gimlet point starts the hole, but Type A screws are not self-drilling, so you still need a pilot in steel of any real thickness.
3) Can I use Metallics JSTS26 screws on a federally funded job with Buy American requirements?
No. The JSTS26 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. On a job with domestic sourcing language in the spec, you need a domestically produced fastener instead.
4) How many Metallics JSTS26 tapping screws come in a jar, and can I buy fewer than that?
The JSTS26 ships in a jar of 100, and 100 is the order minimum. If you need a different size or count, Metallics notes other sizes and quantities are available by request.
5) How much torque can a #12 slotted pan head stainless tapping screw take before it twists off?
Minimum torsional strength on the JSTS26 is 83 lb-in. Slotted drive is the limiting factor in practice, since a flat blade cams out of the slot long before you reach that. Slot width runs 0.056 to 0.067 in. and slot depth 0.061 to 0.077 in., so use a driver bit matched to that slot rather than an impact gun.
6) What are the head dimensions on the Metallics JSTS26, and will the head sit inside a knockout or clearance hole?
Pan head, 0.407 to 0.425 in. across and 0.112 to 0.125 in. tall. That head bears on the surface rather than countersinking, so the hole underneath only needs shank clearance, not a chamfer. If the fixture calls for a flush face, a pan head is the wrong profile.
7) What thickness of material can a 1/2 inch #12 tapping screw hold, and how coarse is the thread?
Thread count is 11 per inch, which is the coarse Type A pitch meant for sheet metal and thin stock. With 1/2 in. of total length, engagement is short: figure on thin gauge sheet, boxes, straps, and covers. For thicker stock or a deeper stack you want a longer screw in the same JSTS series.
8) What standards do Metallics JSTS tapping screws conform to?
Head and drive dimensions follow ASME B18.6.3-2013; the thread is to ASME B18.6.4. One caveat from Metallics: dimensions for #9 diameter screws in this family fall outside ASME B18.6.4.
9) What trades actually use the Metallics JSTS26 stainless tapping screw?
Metallics lists it for the electrical, plumbing, heating and air conditioning industries. In practice that means mounting plates, straps, covers, and sheet metal work where stainless is wanted for corrosion resistance and a slotted pan head is acceptable.
10) How much does a jar of 100 Metallics JSTS26 screws weigh and how big is the container?
The jar weighs 0.66 lbs and measures 3 x 3 x 2.15 in. Small enough to keep several sizes on the van without giving up a drawer.
