Metallics JTS3 – Frequently Asked Questions
1) Will a #4 x 5/8 in. sharp point tapping screw bite into sheet metal without a pilot hole?
The JTS3 is a Type A tapping screw with a gimlet (sharp) point, which is the point style meant to start in thin sheet metal and form its own thread as it drives. It is specified for sheet metal application with 24 threads per inch in a UNC thread form. In heavier gauge stock a pilot hole is still the right practice; the sharp point is for light sheet, not structural steel.
2) Do these Metallics tapping screws meet Buy American and ARRA requirements for a public project?
The JTS3 is flagged ARRA compliant and Buy American compliant, with country of origin listed as multiple. For a federally funded job, those two compliance flags are the ones procurement usually asks for on fasteners.
3) Is a Type A tapping screw the right choice, or do I need a self-drilling screw?
A Type A screw like the JTS3 taps its own thread in a pre-punched or pre-drilled hole in thin sheet, using a sharp gimlet point. It does not drill its own hole. If you are fastening into stock with no existing hole and do not want to pre-drill, a self-drilling (Type TEK) screw is the one to use. For enclosure, raceway, and sheet metal work where the hole is already there, the Type A is the standard pick.
4) Can I drive the Metallics JTS3 tapping screw with a Phillips bit, or does it need a slotted driver?
Either works. The JTS3 has a combination slotted/Phillips pan head, so a #1 Phillips bit or a flat blade will drive it. The Phillips recess is 0.115 in. diameter with a 0.053 to 0.071 in. gaging depth, and the slot runs 0.031 to 0.039 in. wide and 0.027 to 0.04 in. deep, so a small cabinet-tip flat blade seats properly.
5) Is the pan head on these #4 screws low enough to clear a device plate or box cover?
Head height runs 0.07 to 0.08 in. with a head width of 0.205 to 0.219 in. That is a low, broad pan profile, so it sits close to the surface and spreads bearing on thin sheet without pulling through. Useful to check against any cover or trim that needs to lie flat over the fastener.
6) Will these zinc plated tapping screws hold up outdoors or in a damp mechanical room?
The JTS3 is steel with a zinc finish, which is an indoor and sheltered-use plating. It handles the humidity of a mechanical room or an interior enclosure, but zinc plated carbon steel is not a marine or sustained-wet-exposure finish. For direct weather or washdown areas, specify a stainless fastener instead.
7) What standards do the Metallics JTS tapping screws conform to?
Dimensions follow ASME B18.6.3-2013 and the thread form follows ASME B18.6.4. Steel is to AISI 1016 through 1024, case hardened to Rockwell C28 to 38. One note worth carrying to a submittal: dimensions for the #9 diameter in the JTS line sit outside ASME B18.6.4.
8) How are the JTS3 screws packaged and is there a minimum I have to buy?
They ship in a jar, with a 100 count order minimum. So the smallest buy is a 100 piece jar, which weighs 0.22 lbs.
