Metallics JTEKD12212SS – Frequently Asked Questions

1) Will a #12 x 2-1/2 in. self-drilling screw hold in exterior or damp locations?
It is 410 stainless steel, a hardenable stainless that gives you corrosion resistance while still being hard enough to drill its own hole (Rockwell C38-46). That combination is why 410 is used for self-drillers rather than 300 series. For heavy salt or chemical exposure 410 is not as resistant as austenitic stainless, so judge it against your site conditions.
2) What driver do I need for the Metallics JTEKD screw with the indented hex washer head?
Hex drive, with a 5/16 in. indented hex head measuring 0.305 to 0.312 in. across the flats and 0.34 in. across corners. A 5/16 in. magnetic hex driver in an impact or screw gun seats it. Head height runs 0.139 to 0.155 in.
3) Does the washer head on this self-drilling screw seal or just spread the load?
The integral washer on the JTEKD12212SS is a bearing surface, not a gasket. It runs 0.398 to 0.432 in. outside diameter with a 0.022 to 0.039 in. thickness, which spreads clamp load over sheet metal, strap, and thin panel material so the head does not pull through. If you need a weathertight joint on a roof or wall panel, you need a screw with a bonded EPDM sealing washer.
4) How much torque can a #12 self-drilling stainless screw take before it twists off?
Minimum torsional strength is 92 lb-in. That is the failure floor, not a driving target, so set your impact driver or clutch well under it. Metallics notes minimum torques are the same for stainless and steel self-drill screws, and drill time is about 2.5 seconds through a 1 mm plate.
5) What thread pitch and standard does the Metallics JTEKD12212SS follow?
14 threads per inch on a #12 diameter, 2-1/2 in. long body. Threads conform to SAE J78 - 2013 and head dimensions to ASME B18.6.3-2010, which is what lets you substitute it for any other Type BSD #12-14 self-drilling screw called out on a drawing.
6) Are these screws acceptable on a federally funded project with Buy American requirements?
Metallics lists the JTEKD12212SS as both ARRA compliant and Buy American compliant, with country of origin China. Procurement officers should take the compliance flag together with the origin when the specification calls for domestic melt and manufacture.
7) Is a 2-1/2 in. self-driller too long for attaching conduit strap to a steel stud?
Often yes. The 2-1/2 in. length on the JTEKD12212SS is meant for going through thick assemblies, wood blocking, or standoff into 0.110 to 0.210 in. steel. Fastening a one-hole strap flat to a stud leaves most of the shank projecting behind the stud face. For flush sheet-to-sheet work, a shorter #12-14 self-driller in the same JTEKD series is the better call, and Metallics offers other lengths in the line.
8) How are these Metallics self-drilling screws packaged and what is the minimum order?
They come in a jar, 100 count, and 100 is the minimum order quantity. Shipping weight on the jar is 2.07 lbs.
