Metallics JTEKD64 – Frequently Asked Questions
1) Do I need to pre-drill a pilot hole for these Metallics hex head screws?
No pilot hole. The JTEKD64 is a Type BSD self-drilling and tapping screw, so the drill point cuts its own hole and the thread taps it in one pass. The description puts drill time at about 2.5 seconds through a 1 mm plate. One driver, one operation, no layout drilling.
2) Will these screws hold up outdoors or in a damp mechanical room?
The JTEKD64 is carbon steel with a zinc finish. Zinc plating is a mild indoor corrosion coating, suitable for dry interior work like enclosures, strut, raceway, and metal stud framing. For exterior exposure, washdown areas, or coastal work, specify a stainless self-drilling screw instead rather than zinc-plated steel.
3) What size driver bit fits the 1/4 indented hex head on the JTEKD64?
A 1/4 in. hex driver or nutsetter. The head measures 0.244 to 0.250 in. across the flats with a width across corners of 0.272 in., and head height runs 0.080 to 0.093 in. A standard magnetic 1/4 in. nutsetter in a screw gun seats it fine, which is why these are the common choice for production sheet metal work over a bit-driven head.
4) Does the washer come attached to the screw or separate?
The washer is part of the fastener on the JTEKD64, under the indented hex head. Washer outside diameter is 0.302 to 0.328 in. with a thickness of 0.015 to 0.025 in. That bearing surface spreads load across thin sheet and helps against pull-through, so there is nothing loose to keep track of on a lift or a ladder.
5) What specs does a Metallics Type BSD self-drilling screw meet for a submittal?
Three to cite on the JTEKD64: dimensions to ASME B18.6.3-2010, thread to SAE J78-2013, and material to AISI 1016-1024 steel. Case hardness is Rockwell C32-40 with a minimum torsional strength of 24 lb-in. Note that SAE J78 does not cover #7 diameter drill screws, so a #7 substitution has no equivalent thread standard behind it.
6) Are Metallics JTEKD screws acceptable on a Buy American or ARRA funded project?
Metallics lists the JTEKD64 as both ARRA compliant and Buy American compliant, with country of origin China. Submit those flags as published; on federally funded work the contracting officer decides what satisfies the clause in your particular contract.
7) Is a #6 x 1-1/4 in. self-drilling screw long enough for my application, and how coarse is the thread?
The JTEKD64 is a #6 diameter, 1-1/4 in. long screw at 20 threads per inch. With a maximum panel thickness of 0.090 in., the 1-1/4 in. length leaves plenty of shank for stacking a bracket, clip, or strap against sheet steel. For thin-to-thin sheet connections where that length would protrude, drop to a shorter #6 in the same JTEKD series.
8) How is the JTEKD64 packaged and what is the smallest quantity I can buy?
These ship in a jar, with an order minimum of 100 count. Practical for a service van or a job box where you want the screws contained rather than loose in a bag.
