Metallics JTEKD35 – Frequently Asked Questions

1) How thick a steel panel will the Metallics JTEKD35 #3 point self-drilling screw go through?
The JTEKD35 is rated for panel thickness of 0.110 to 0.210 inch, which is the working range of its #3 drill point. Below 0.110 inch the point can strip rather than form clean threads; above 0.210 inch you need a heavier drill point. Thread count is 14 per inch, UNC.
2) Are zinc plated self-drilling screws like these OK for outdoor or damp electrical work?
The JTEKD35 is carbon steel with a zinc plated finish, which is a mild corrosion coating intended for dry indoor use, interior strut, duct, and panel work. For exterior, coastal, wash-down or wet-location mounting, specify a stainless self-drilling screw instead; zinc plating will eventually rust through in those conditions.
3) Will a #12 self-drilling screw hold in 16 gauge steel stud without pre-drilling?
Yes. The #3 drill point drills and taps its own hole in one pass, no pilot needed, within the 0.110 to 0.210 inch panel range. Common 16 gauge structural stud at roughly 0.060 inch is thinner than that range, which means the point can over-drill and spin out before the threads engage; for light gauge stud a #2 point screw is the better match. Use the JTEKD35 on heavier plate, channel, and bar stock inside its stated range.
4) Do these self-drilling screws come with a washer, or do I buy them separately?
The washer is integral to the head, so nothing extra to order. The bonded washer has an outside diameter of 0.398 to 0.432 inch and a thickness of 0.022 to 0.039 inch, giving you a wider bearing surface against sheet metal or strut than a plain hex head would.
5) How many Metallics JTEKD35 screws come in a pack and can I buy just a few?
These ship in a jar with a 100 count minimum, so the smallest purchase is 100 pieces. The jar runs about 1.03 lbs.
6) What standards do these Metallics hex washer head drill screws meet?
Dimensions follow ASME B18.6.3-2010 and threads follow SAE J78-2013. Steel is AISI 1016 to 1024, case hardened to Rockwell C32-40, with a minimum torsional strength of 92 lb-in. Those are the numbers a spec reviewer will want for a submittal on a Type BSD drill screw.
7) Are these screws Buy American and ARRA compliant for a government job?
The JTEKD35 is flagged both Buy American compliant and ARRA compliant in the manufacturer data, with country of origin listed as multiple. On a federally funded project, pull the mill documentation for the specific lot you receive before it goes into a submittal package.
8) How much torque can I put on a #12 drill screw before the head snaps?
Minimum torsional strength on the JTEKD35 is 92 lb-in. Set the clutch on your screwgun below that and let the point do the drilling. Metallics notes drill time of 2.5 seconds for a 1 mm plate, and that minimum torque figures are the same for stainless and steel drill screws.
