Metallics JTEKD6 – Frequently Asked Questions

1) What gauge metal will a #2 point self-drilling screw actually drill through?
The #2 drill point on the Metallics JTEKD6 screw drills steel from 0.035 to 0.110 inches thick, which covers typical sheet metal duct, strut backing, and light enclosure steel. Thinner than 0.035 and the point can push the material rather than cut it; thicker than 0.110 and you are past what a #2 point is rated to penetrate, so you would need a heavier drill point or a pre-drilled hole with a tapping screw.
2) Do I need to pre-drill for the Metallics #10 x 3/4 inch hex head screw?
No pre-drilling. It is a Type BSD self-drilling and tapping screw, so the point cuts its own hole and the 16 threads-per-inch thread taps it in the same pass, as long as the steel falls in the 0.035 to 0.110 inch range the point is rated for. One tool, one step, no pilot bit.
3) Will a 3/4 inch self-drilling screw be long enough for my application?
Length is the part people get wrong on self-drillers. At 3/4 inch overall, this Metallics #10 screw has to drill through the full stack before the threads start pulling, so it suits a panel-to-frame joint where combined steel thickness stays in the 0.035 to 0.110 inch range the #2 point handles. Mounting a bracket or box with a thick backplate to structural steel is a job for a longer screw with a heavier point.
4) Will these fasteners satisfy a Buy American requirement on a federal or public project?
No. The Metallics JTEKD6 self-drilling screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing clause, these will not clear it and you need a domestically manufactured fastener instead.
5) What size driver or socket do I need for these Metallics indented hex head screws?
A 5/16 inch hex driver. The indented hex head measures 0.305 to 0.312 inches across the flats and 0.34 across the corners, so a standard 5/16 magnetic nut setter seats on it. The head stands 0.105 to 0.12 inches tall, which is low enough that it will not foul a panel sitting tight against the fastened surface.
6) Does this screw need a separate washer, or is one built in?
The washer is part of the head, so nothing extra to order or fumble with overhead. It runs 0.384 to 0.414 inches outside diameter and 0.019 to 0.031 inches thick, giving you a bearing surface roughly a third larger than the hex head alone. That spread is what keeps the head from pulling through thin duct or enclosure sheet and helps hold a flat seat on a slotted or oversized hole.
7) Can I run these screws with an impact driver without snapping the heads off?
They are rated to 61 lb-in minimum torsional strength at Rockwell C32-40 hardness, which is what lets the point stay hard enough to cut steel while the shank resists twisting off. That said, an impact will happily exceed 61 lb-in once the washer seats. Drive them with a screw gun or a clutched driver and back off as soon as the washer contacts the panel; running an impact past seating is the usual cause of a snapped self-driller.
8) Are zinc plated self-drilling screws OK for outdoor or damp locations?
Zinc plating over steel is a mild corrosion coating, suited to indoor electrical, plumbing, and HVAC work: enclosures, duct, equipment panels, and mechanical rooms. The core is carbon steel to AISI 1016-1024. For sustained exterior exposure, coastal air, or wet process areas, specify a stainless or coated exterior-rated self-driller instead of zinc.
9) Do these Metallics screws meet a recognized fastener standard for submittals?
Two standards are called out: the thread conforms to SAE J78-2013, the standard covering steel self-drilling tapping screws, and the head dimensions conform to ASME B18.6.3-2010. Between them you can match thread pitch and head geometry against a spec sheet or a submittal without measuring a sample.
10) What is the difference between a self-drilling screw and a self-tapping sheet metal screw?
A self-tapping screw forms its own thread but needs a pilot hole drilled first. A self-driller like this Type BSD #10 carries a drill point on the tip, so it makes the hole and cuts the thread in one pass. Pick the self-driller when you are fastening into steel in the 0.035 to 0.110 inch range and want to skip the pilot step. Pick a plain sharp-point sheet metal screw for very thin gauge or non-metal substrates, where a #2 drill point flutes will not engage properly.
11) Is the JTEKD6 the right screw for hanging unistrut brackets and mounting junction boxes to metal studs?
For metal stud and light steel work, yes. The #10 diameter with 16 TPI and a #2 point handles the 0.035 to 0.110 inch steel typical of studs, enclosures, and duct, and the integrated washer spreads the load on the knockout or mounting ear. Where the JTEKD6 is the wrong call is anchoring to structural steel beams or heavy channel, where the stack exceeds 0.110 inches.
12) How many screws come in a pack, and can I buy fewer than 100?
They ship in a jar of 100, and 100 is the order minimum, so the jar is the smallest unit you can take. The full jar weighs 0.635 lbs. For a service van or a single panel change-out that is one jar; for a duct run or a repetitive assembly, order in multiples of the jar.
