Metallics JTSF18SS – Frequently Asked Questions

1) What size pilot hole and material thickness suit a #8 x 1/2 in. Type A tapping screw?
The Metallics JTSF18SS is a Type A tapping screw with a gimlet point, 15 threads per inch, and a 0.267 in. gaging diameter. Type A with a gimlet point is meant for thin sheet metal, where the point starts the hole and the coarse thread forms its own mating thread. At 1/2 in. total length under a flat head, usable thread engagement is short, so it suits sheet metal, enclosures, and panel work rather than thick stock.
2) Will these stainless screws cause corrosion if I drive them into aluminum enclosures?
They can. Driving 18-8 stainless fasteners into aluminum or steel creates a galvanic couple in some environments, which corrodes the lighter metal around the screw. On exterior aluminum or damp locations, isolate the joint or use a fastener matched to the base metal. For dry interior panel and enclosure work the 18-8 stainless material is the reason to pick it, since the screw itself will not rust.
3) What driver bit do I need for the JTSF18SS flat head screws?
A #2 Phillips bit. The recess measures 0.182 in. diameter, 0.11 in. deep, with a 0.03 in. recess width, which is standard #2 Phillips geometry. Using a #1 bit will cam out and chew the recess; stainless recesses are softer than hardened steel, so seat the bit fully and keep the drill speed down.
4) How tight can I drive these before they snap?
Minimum torsional strength is 39 lb-in. That is the twist the screw body will take before failing, and it is low enough that an impact driver will shear the heads in a hurry. Drive them with a clutch-set drill or by hand and stop as soon as the flat head seats.
5) Do these Metallics tapping screws meet a published dimensional standard for spec work?
Yes. The JTSF series is built to ASME B18.6.4-1998 for dimensions and ASME B18.6.4 for threads, which is the standard a submittal reviewer will look for on tapping screws. One caveat the manufacturer notes: dimensions for #9 diameter screws fall outside ASME B18.6.4. The #8 size is covered.
6) Are these screws acceptable on a Buy American or ARRA funded project?
The JTSF18SS is flagged ARRA compliant and Buy American compliant in the manufacturer's data, with country of origin listed as multiple. For federally funded work, carry that compliance flag on your submittal.
7) How are the JTSF18SS screws packaged and what is the minimum order?
They ship in a jar of 100, which is the order minimum (100 count). Jar packaging suits a service van or a stockroom bin better than a loose bag. The jar runs 0.31 lbs.
8) Can I get the same screw in a longer length or a bigger jar?
Other sizes and quantities in the JTSF flat head Phillips tapping screw line are available by request. The JTSF18SS itself is fixed at #8 diameter by 1/2 in. length in 18-8 stainless, one model, so if you need more thread engagement than 1/2 in. gives you, ask for the longer length rather than ordering this one.
