Metallics TSF22M – Frequently Asked Questions

1) Do I have to drill a pilot hole for a Type A tapping screw, or does it cut its own?
The TSF22M is a Type A tapping screw with a gimlet point, so it forms its own thread in sheet metal, thin plate or soft materials once a clearance hole is present in the mating part. The point starts the hole in light gauge material, but it is not a self-drilling (Type TEK) screw, so there is no drill flute to cut through heavier stock. Thread count is 15 per inch, which is the coarse Type A spacing that gives bite in thin material.
2) Can I use the Metallics TSF22M on a federally funded or Buy American job?
No. The TSF22M is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a project with domestic sourcing requirements in the specs, you need a domestically produced tapping screw instead.
3) What driver bit do I need for the Metallics TSF22M #8 Phillips tapping screws?
A #2 Phillips bit. The TSF22M uses a Phillips drive with a recess 0.182 in. across, 0.11 in. deep and 0.03 in. wide, which is the standard #2 recess. Keep the bit seated and square; the screw is rated to 39 lb-in minimum torsional strength, so an impact driver run wide open can twist the head off before the thread seats.
4) Are Metallics TSF22M screws okay for outdoor or damp locations?
These are carbon steel with a zinc finish, which is a dry-location plating. Zinc plated steel handles indoor electrical work, panel and enclosure assembly, and occasional condensation, but it will corrode in sustained wet, coastal or chemically aggressive conditions. For those openings go to a stainless tapping screw instead.
5) Is the TSF22M sold loose or do I have to buy a full box?
It ships as a jar of 1,000 screws, and 1,000 is the order minimum. That is the standard contractor pack for #8 tapping screws, so plan quantity in thousands rather than by the handful.
6) Do these Metallics tapping screws meet a recognized dimensional standard for submittals?
The TSF22M is made to ASME B18.6.4-1998 for dimensions and ASME B18.6.4 for the thread form, with steel to AISI 1016-1024 and a case hardness of Rockwell C28-38. Those are the three figures a submittal reviewer usually wants on a tapping screw. Note that #9 diameter dimensions in this family fall outside B18.6.4, though that does not apply to this #8 size.
7) How thick a material will a 1-1/4 in. #8 tapping screw hold in?
Overall length is 1-1/4 in. under the head, since a flat head is measured to the top of the head. Subtract the thickness of the part you are fastening through and the rest is available for thread engagement in the base material. For sheet metal work that is plenty; a few threads of engagement is all a Type A screw needs. Gaging diameter is 0.267 in., with the head protruding 0.023 to 0.039 in. above the gage.
