Metallics JTSS36 – Frequently Asked Questions

1) What driver bit do I need for the Metallics JTSS36 square drive tapping screws?
Use a #3 square (Robertson) bit. The JTSS36 is specified with a square drive and a 3R driver size. The recess measures 0.133 across the flats with a gaging depth of 0.080 to 0.095 inch, so a worn or undersized bit will cam out and chew the recess.
2) Is a Type A tapping screw the right choice for sheet metal, or do I need a self-drilling screw?
A Type A tapping screw like the JTSS36 forms its own thread but does not drill its own hole. The gimlet point starts in thin sheet metal and soft materials, but you still need a pilot hole in heavier gauge stock. If you want to skip the pilot hole entirely in steel, you want a self-drilling (Type TEK) screw instead.
3) Do these Metallics screws meet Buy American requirements for a federal job?
No. The JTSS36 is not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your project has domestic-sourcing language in the spec, you will need a documented domestic fastener instead.
4) What size and thread does the Metallics JTSS36 screw have?
It is a #12 diameter screw, 1-1/2 inches long, with 11 threads per inch on the Type A thread form. Threads are made to ASME B18.6.4 and head dimensions to ASME B18.6.3-2013, so it interchanges with any other #12 x 1-1/2 Type A pan head from a spec-compliant source.
5) How much room does the pan head take up, and will it sit flat against a panel?
The pan head runs 0.407 to 0.425 inch across and 0.139 to 0.151 inch high. A pan head bears on the surface rather than countersinking, so it sits proud by about an eighth of an inch and needs a flat, unrecessed landing. If you need the head flush, a flat head screw and a countersunk hole are what you want.
6) Are these Metallics tapping screws tough enough to drive without snapping heads?
They are heat treated to Rockwell C28-38 with a minimum torsional strength of 83 lb-in, made from AISI 1016-1024 steel. That is the standard duty range for Type A tapping screws. Drive them with a clutch or torque-limiting driver rather than an impact gun and you will not twist heads off.
7) Can I use zinc plated tapping screws outdoors or in a damp mechanical room?
The JTSS36 is zinc plated steel, which handles indoor and dry mechanical spaces fine but is not a marine or sustained-wet finish. For rooftop units, exterior walls, or washdown areas, step up to stainless or a hot dip galvanized fastener.
8) How do the Metallics JTSS36 screws come packaged and what is the minimum order?
They ship in a jar of 100, which is the order minimum. The jar weighs 1.38 lbs. Handy for a truck stock bin rather than a loose-count bag.
9) What trades actually use these pan head square drive tapping screws?
Metallics lists the JTSS36 for electrical, plumbing, heating and air conditioning work. Typical uses are fastening to sheet metal enclosures, duct, strut accessories and panel work where a square drive keeps the bit from camming out overhead.
