Metallics JTSS7SS – Frequently Asked Questions

1) What driver bit do I need for the Metallics JTSS7SS square drive screws?
A #2 square (Robertson) bit. The spec calls out driver size 2R, with a recess 0.112 inch across flats and a gaging depth of 0.060 to 0.075 inch. Bring a square bit, not a Phillips, and seat it fully to avoid camming out of the recess.
2) Do I need to pre-drill for a #8 x 1/2 in. Type A tapping screw?
The JTSS7SS is a Type A tapping screw with a gimlet point, so it forms its own thread in sheet metal, and in thin stock it will start on its own. In heavier gauge you still want a pilot hole sized to the root of the thread. Thread pitch is 15 threads per inch to ASME B18.6.4.
3) Can I use stainless tapping screws to fasten into aluminum or steel enclosures?
You can, but watch the dissimilar metal contact. Metallics flags that fastening stainless steel parts to aluminum or steel can set up a galvanic couple and corrode in some environments, so in wet or coastal locations use an isolator or a matched fastener. Indoors and dry, 18-8 stainless is the usual choice for corrosion resistance.
4) Are these screws Buy American or ARRA compliant for a government job?
No. The JTSS7SS is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries domestic sourcing requirements, this part will not satisfy them.
5) How many Metallics JTSS7SS screws come in a jar?
They ship in a jar of 100, which is the order minimum. Metallics notes other sizes and quantities are available by request.
6) Will these screws strip when driven with an impact driver?
The JTSS7SS is rated to a minimum torsional strength of 39 lb-in. An impact driver will exceed that easily, so run a clutch-equipped drill on a low setting or drive by hand. The square recess resists cam-out better than Phillips, but the screw body is the limit, not the drive.
