Metallics JTEKD2M – Frequently Asked Questions

1) What metal thickness will the Metallics JTEKD2M self-drilling screw drill through?
The JTEKD2M is rated for panel thicknesses of 0.035 to 0.100 inch. That covers typical sheet metal studs, strut, hat channel and light gauge decking. Go thicker than 0.100 inch and the #2 drill point is out of range, so you want a larger drill point size instead.
2) Is the JTEKD2M screw Buy American and ARRA compliant for a federal job?
Both compliance flags are marked compliant on the JTEKD2M, with country of origin listed as multiple. For a federally funded spec, cite the Buy American and ARRA compliant status along with the ASME B18.6.3-2010 dimensional standard and SAE J78-2013 thread standard it is built to.
3) Do I need to pre-drill a pilot hole for these screws?
No. It is a Type BSD self-drilling and tapping screw with a #2 drill point, so it drills its own hole and forms its own thread in one pass. One driver, one pass, no pilot and no separate tap, which is the point of the design on light gauge steel.
4) What driver do I need for the JTEKD2M hex head screw?
A 1/4 inch hex driver. The head is an indented hex with a hex drive, measuring 0.244 to 0.25 inch across the flats and 0.272 across the corners, with a head height of 0.096 to 0.11 inch. A standard 1/4 inch magnetic nut setter in a drill or impact driver runs them.
5) Does this Metallics screw come with a washer already on it, or do I order washers separately?
The washer is integral to the head, so nothing extra to order. Washer OD runs 0.322 to 0.348 inch with a thickness of 0.019 to 0.031 inch, which spreads the clamp load and helps seat against thin sheet metal without dimpling it.
6) How many JTEKD2M screws come in a jar and is there an order minimum?
They ship in jars of 1,000, and 1,000 is the order minimum. Jar weight is listed at 4.11 lbs. If you need a different size or a different count, Metallics makes other sizes and quantities available by request.
7) Will these screws strip out or snap when driven with an impact driver?
Minimum torsional strength on the JTEKD2M is 42 lb-in, with case hardness at Rockwell C32-40. That hardness is what lets the point cut steel without rolling over. Drill time is about 2.5 seconds through a 1 mm plate. Snapping usually means you kept driving after the head seated, so back off the trigger once the washer pulls tight.
8) Are these zinc screws okay for outdoor or damp locations?
The JTEKD2M is carbon steel (AISI 1016-1024) with a zinc finish. Zinc plating is a dry-location and protected-location coating, so it is fine for interior electrical work, strut, and panel mounting. For exterior, coastal, or wet duty, specify a stainless self-drilling screw instead.
9) What is the thread pitch on the #8 Metallics self-drilling screw?
18 threads per inch, UNC. That is the standard machine-screw thread for a #8 self-drilling fastener, so it will mate with 8-18 tapped holes and cut its own in sheet metal within the 0.035 to 0.100 inch panel range. Screw length is 3/4 inch.
