Metallics JSTSP36 – Frequently Asked Questions

1) What driver bit do I need for the Metallics JSTSP36 tapping screws?
A #3 Phillips bit. The recess on these 1/4 x 1 inch pan head screws is 0.281 to 0.268 inch in diameter, 0.161 inch deep, with a 0.036 inch recess width, so a #2 bit will cam out and chew the recess under torque. Keep a #3 in the driver if you are running a jar of these.
2) Do Type A tapping screws like the JSTSP36 need a pilot hole, or do they self-drill?
They need a pilot hole. The JSTSP36 is a Type A tapping screw with a gimlet point, which means it is pointed and cuts its own thread in sheet metal or a pre-drilled hole, but it does not drill through material the way a self-drilling point does. Drill or punch first, then drive the screw to form the thread.
3) Will stainless tapping screws cause corrosion if I fasten them into aluminum or steel?
They can. These are 18-8 stainless screws, and fastening stainless parts to aluminum or steel sets up a galvanic couple in some environments, which corrodes the less noble metal. On exterior or damp work into aluminum enclosures or strut, isolate the joint or use a matched-metal fastener instead. Dry indoor electrical work with stainless into steel is the common use and is where these fit.
4) What standards do the Metallics JSTSP tapping screws conform to?
Head and recess dimensions follow ASME B18.6.3-2013, and the thread follows ASME B18.6.4. For a submittal, that is the pair of designations to cite. One caveat worth knowing across the JSTSP series: dimensions for #9 diameter screws are independent of ASME B18.6.4.
5) Are Metallics JSTSP36 screws acceptable on a Buy American or ARRA job?
The JSTSP36 is flagged both ARRA compliant and Buy American compliant, with country of origin China. If your specification is a strict domestic-melt-and-manufacture clause rather than an ARRA-style provision, have the spec writer confirm which rule applies before you submit these.
6) Is a 1 inch tapping screw long enough for sheet metal boxes and strut?
The JSTSP36 has a 1 inch fastener length under a 1/4 inch diameter, which is sized for threading into sheet metal, thin plate, and bracket stock where you only need a short thread engagement. Type A threads form in the material, so you want the hole thickness matched to the screw rather than trying to pull a deep clamp load. For thicker structural steel or a through-bolted connection, a machine screw and nut or a self-drilling screw rated for that thickness is the better call.
7) How are the JSTSP36 screws packaged and what is the minimum I can order?
They ship in a jar of 100, and 100 count is the order minimum, so you are buying by the jar rather than by the piece. Figure about 1.43 lbs for the packed jar. Other sizes and quantities in the JSTSP series are available by request.
