Metallics JTEK2PSS – Frequently Asked Questions
1) What metal thickness can the Metallics JTEK2PSS #8 self-drilling screw drill through?
The JTEK2PSS is rated for panel thickness of 0.035 to 0.100 inch, so it handles light gauge steel like studs, strut, raceway and enclosure panels. Below 0.035 inch the #2 drill point can strip rather than tap clean threads; above 0.100 inch you need a heavier drill point.
2) How much torque will these screws take before they snap?
Minimum torsional strength is 42 lb-in, with the screw hardened to Rockwell C38-46. Metallics notes minimum torques are the same for stainless and steel self-drill screws, and drill time runs about 2.5 seconds through a 1 mm plate. Set an impact or screwgun clutch below that 42 lb-in figure; running a high-torque impact wide open is how these break off in the panel.
3) Do I need to pre-drill a pilot hole for these self-drilling screws?
No. The JTEK2PSS is a Type BSD self-drilling and tapping screw with a #2 drill point, so it cuts its own hole and forms the thread in one pass on panel 0.035 to 0.100 inch thick. One tool, one operation, no pilot and no tap.
4) Is a 410 stainless self-drilling screw okay for outdoor or damp electrical work?
410 stainless is a hardenable martensitic stainless, which is what lets this screw drill its own hole and still resist corrosion better than plain carbon steel. It suits damp and exterior light-gauge metal work. For salt spray or coastal exposure, 410 is less corrosion resistant than 300 series stainless, so specify accordingly.
5) What driver bit do I need for these Metallics pan head Phillips self-drilling screws?
A #2 Phillips bit. The recess diameter is 0.175 inch with a gaging depth of 0.071 to 0.097 inch, so a worn or oversized bit will cam out before the screw seats.
6) Will a #8 pan head sit flush enough under a cover plate or clamp?
No, a pan head sits on top of the surface. Head width runs 0.306 to 0.322 inch and head height 0.105 to 0.115 inch, so budget roughly an eighth of an inch of projection. If you need the fastener below the surface you want a flat or wafer head instead.
7) What thread pitch and standard do these Metallics JTEK screws follow?
18 threads per inch on a #8 diameter, built to SAE J78 - 2013 for the thread and drill screw requirements and ASME B18.6.3-2010 for head dimensions. That matters on spec jobs where the submittal calls out a dimensional standard rather than a brand.
8) Do these Metallics screws meet Buy American and ARRA requirements for a public job?
Metallics lists the JTEK2PSS as both Buy American compliant and ARRA compliant, with country of origin recorded as multiple. That is the documentation a government, school or healthcare procurement file usually asks for on fasteners.
9) How are the Metallics JTEK2PSS screws packaged and what is the minimum order?
They ship in a jar, 100 count minimum. Jar weight is 0.46 lbs. Other sizes and quantities are available by request.
