Metallics JTEKD1V – Frequently Asked Questions

1) What metal thickness can the Metallics JTEKD1V self-drilling screw drill through?
The JTEKD1V is rated for panel thicknesses of 0.035 to 0.100 inch, so it handles light to medium gauge sheet steel, studs, and strut. Go thicker than 0.100 inch and the #2 drill point is out of its range, so you want a larger drill point size instead.
2) Do I need to pre-drill a pilot hole for these #8 hex head screws?
No. This is a Type BSD self-drilling and tapping screw with a #2 drill point, so it cuts its own hole and forms its own thread in one pass within the 0.035 to 0.100 inch panel range. The description notes a 2.5 second drill time on a 1 mm plate.
3) What size driver bit fits the JTEKD1V screw head?
It takes a 1/4 inch hex driver. The indented hex washer head measures 0.244 to 0.25 inch across the flats and 0.272 inch across the corners, with a head height of 0.096 to 0.11 inch. A standard 1/4 inch magnetic nut setter in a screw gun is all you need.
4) How many screws come in a jar, and is there an order minimum?
They ship in a jar of 500 count, which is also the order minimum. Jar weight is listed at 1.69 lbs.
5) Will the washer head on these screws seal or hold thin sheet metal without pulling through?
The integral washer head spreads the clamp load: washer OD runs 0.322 to 0.348 inch with a washer thickness of 0.019 to 0.031 inch. That bearing surface is what keeps a #8 screw from pulling through light gauge sheet. It is a bonded-washer style head for load spread, not a rubber sealing washer, so it is not a weatherproofing fastener.
6) Are these screws Buy American and ARRA compliant for a government or institutional job?
Both flags are marked compliant on the Metallics JTEKD1V, with country of origin listed as multiple. Procurement buyers specifying for federally funded work should note the compliance designation along with the governing standards: ASME B18.6.3-2010 dimensionally and SAE J78-2013 for the thread.
7) Can I use these zinc plated screws outdoors or in a damp location?
The JTEKD1V is carbon steel with a zinc finish, which is a dry-interior-rated coating. For exterior, roof, or wet-location work, specify a stainless self-drilling screw instead. Metallics notes minimum torques are the same for stainless and steel self-drill screws, so you lose nothing in driving performance by going stainless.
8) What thread does the JTEKD1V run, and will it match a #8-18 spec on my drawing?
Thread is UNC at 18 threads per inch on a #8 diameter, 1/2 inch long, which is the standard #8-18 self-drilling callout to SAE J78-2013. Note that SAE J78 does not cover #7 diameter drill screws, so if a drawing calls out a #7, it is not a J78 item.
9) How much torque can a #8 self-drilling screw take before it snaps in the gun?
Minimum torsional strength is 42 lb-in, with case hardness at Rockwell C32-40 and base material to AISI 1016-1024. Set your impact or screw gun clutch below that and you will not shear heads off driving into 0.035 to 0.100 inch panel.
