Metallics JTSF20 – Frequently Asked Questions

1) Will the Metallics JTSF20 screw sit flush in a countersunk hole?
Yes, it is a flat head, so it seats flush in a countersunk or dimpled hole. The head measures 0.285 to 0.312 in. across with a head height of 0.084 to 0.100 in., so plan the countersink around that diameter if you need a truly flush face.
2) What pilot hole should I drill for an 8 x 3/4 in. Metallics tapping screw?
Size the pilot off the shank: the JTSF20 has an outside diameter of 0.162 to 0.168 in. with a thread width of 0.116 to 0.123 in., so the hole wants to be close to that minor thread dimension in sheet metal so the threads cut and hold. Thread count is 15 per inch at a 0.164 pitch.
3) Are Metallics JTSF20 screws acceptable on a Buy American or ARRA funded job?
No. The JTSF20 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On federally funded work with domestic sourcing language, you will need a domestic fastener instead.
4) What size driver bit do I need for the Metallics JTSF20 tapping screws?
A #2 Phillips bit drives the JTSF20. The screw uses a Phillips drive with a #2 point size, which is the standard bit most electricians already have in the pouch for #8 screws.
5) Are these Metallics screws hard enough to cut their own threads in steel boxes and strut?
They are case hardened to Rockwell C28-38 and made from AISI 1021-1045 steel, which is what lets the thread form cut into sheet steel rather than strip. For enclosures, device boxes, and duct work that is the normal working range.
6) Do Metallics JTSF20 screws meet a recognized dimensional spec?
They are built to ASME B18.6.4-1998, the standard covering thread forming and thread cutting tapping screws. If a submittal calls out B18.6.4 dimensions for a #8 flat head Phillips, these conform.
7) Will these zinc plated screws hold up outdoors or in a damp mechanical room?
The JTSF20 is steel with a zinc finish, which is a plated coating meant for dry interior and protected work, electrical, plumbing, and HVAC applications. For sustained wet exposure or exterior use, a stainless fastener is the better call.
8) How do these Metallics tapping screws come packaged, and is there a minimum order?
They ship in a jar of 100, and 100 is the order minimum. The jar runs about 163 g, so it is an easy item to stage on a truck or in a stockroom bin.
9) Can I get this Metallics flat head Phillips tapping screw in other lengths or pack counts?
Yes. The JTSF series covers other diameters, lengths, and quantities beyond the 8 x 3/4 in. JTSF20, available by request. Give the diameter, length, and count you need.
