Metallics JTEKD8SS – Frequently Asked Questions
1) How thick a metal panel will the Metallics JTEKD8SS self-drilling screw drill through?
The JTEKD8SS is rated for panel thicknesses of 0.110 to 0.175 inch. That is the range the #3 drill point is sized to cut and tap in one pass. Thinner sheet than 0.110 inch or steel heavier than 0.175 inch calls for a different drill point number.
2) Is this screw suitable for exterior or damp locations?
The screw is 410 stainless steel, which gives corrosion resistance that plain carbon steel self-drillers do not have, while staying hard enough to drill its own hole. Hardness is Rockwell C38-46. For hardware mounted outdoors or in wash-down and humid areas, that is the reason to pick a 410 stainless self-driller over a zinc-plated one.
3) Does the washer come attached to the screw, and how wide is it?
Yes, the sealing washer is part of the assembly on the JTEKD8SS. Washer outside diameter runs 0.384 to 0.414 inch with a thickness of 0.019 to 0.031 inch, so it spreads the load across the sheet metal without needing a separate loose washer in your pouch.
4) How many Metallics JTEKD8SS screws come in a pack?
They ship in a jar of 100, which is the order minimum (100 count). One jar weighs 1.14 lbs.
5) What thread does a #10 self-drilling screw like this use, and will it hold in tapped steel?
It is a UNC thread at 16 threads per inch in a #10 diameter, cut to SAE J78 - 2013. The screw taps that thread itself as it drills, so it mates with the hole it creates. Minimum torsional strength is 61 lb-in, which is the figure that matters when you are running these with an impact or a high-torque screwgun.
6) Do these Metallics screws meet Buy American requirements for a government or institutional job?
The JTEKD8SS is flagged as both Buy American compliant and ARRA compliant in the manufacturer data. Country of origin is listed as multiple, so if your contract requires a single named origin on the submittal, that is the point to verify before you spec it.
7) Will stainless self-drillers drive slower than steel ones?
No. Per the Metallics data, minimum torques are the same for stainless and steel self-drill screws, with a drill time of 2.5 seconds through a 1 mm thick plate. You are not trading drive speed for the 410 stainless corrosion resistance.
8) What dimensional standard does this indented hex washer head screw conform to?
Head geometry follows ASME B18.6.3-2010 and the thread follows SAE J78 - 2013. That pairing is what lets a specifier call out a Type BSD self-drilling and tapping screw on a drawing and get a repeatable head and thread from any lot.
