Metallics JTEKD4V – Frequently Asked Questions
1) What metal thickness can the Metallics JTEKD4V self-drilling screw drill through?
The JTEKD4V is rated for panel thicknesses of 0.035 to 0.110 inch, which covers typical light-gauge steel studs, strut, and sheet metal enclosures. Its #2 drill point cuts its own hole, so no pilot drilling is needed within that range. Go thicker than 0.110 inch and you want a larger drill point.
2) Are these screws suitable for a Buy American or ARRA funded job?
Metallics lists the JTEKD4V as both ARRA compliant and Buy American compliant. Country of origin is multiple, so if your specification requires documentation of a single origin, request the mill paperwork for the lot you receive.
3) Do I need to pre-drill before driving these screws into metal studs?
No pilot hole. The #2 drill point drills, taps, and fastens in one pass, and Metallics cites roughly 2.5 seconds of drill time on a 1 mm plate. Use a drill or impact driver with a 1/4 inch nut setter and keep steady pressure so the point cuts rather than work-hardens the steel.
4) How many screws come in a jar of Metallics JTEKD4V?
They ship 500 to a jar, and 500 count is the order minimum. That is the usual quantity an electrical contractor buys for mounting straps, boxes, and strut to light-gauge steel.
5) Will the washer head on these #10 self-drilling screws seal or spread load on sheet metal?
The integral washer runs 0.384 to 0.414 inch outside diameter and 0.019 to 0.031 inch thick, which spreads clamp load over thin sheet so the head does not pull through. It is a bare steel washer head, not a bonded rubber sealing washer, so treat it as a bearing surface rather than a weather seal.
6) What standards do these Metallics Type BSD self-drilling screws meet?
Dimensionally they are built to ASME B18.6.3-2010, with threads per SAE J78-2013 in a UNC form at 16 threads per inch. Steel is AISI 1016 to 1024, case hardened to Rockwell C32-40, with 61 lb-in minimum torsional strength. That hardness is what lets the point drill steel without the screw snapping.
7) Can I use these zinc plated self-drilling screws outdoors or in a wet location?
Zinc plated carbon steel is a dry indoor finish. The JTEKD4V is steel with a zinc plating, fine for interior stud work, strut, panels, and enclosures, but exposed exterior or damp runs will corrode the plating over time. For outdoor or corrosive service choose a stainless self-drilling screw instead.
8) Is a 1/2 inch long #10 screw long enough for my application?
At 1/2 inch overall it is a short fastener, sized to drill and tap a single light-gauge member plus whatever thin strap or clip you are holding to it. Panel thickness capacity is 0.035 to 0.110 inch. If you are stacking a thicker bracket or passing through a thick spacer, step up to a longer length in the same JTEKD series.
