Metallics JTEKD18 – Frequently Asked Questions

1) How thick a steel panel can a #2 drill point self-drilling screw go through without pre-drilling?
The Metallics JTEKD18 #2 drill point is rated for steel panel thickness of 0.035 to 0.110 inches. That covers typical light-gauge framing, duct, strut backing plates and enclosure flanges. Go thicker than 0.110 and the point burns up before it drills through, so step up to a #3 or heavier point instead.
2) Do these Metallics screws meet Buy American requirements on a federal job?
No. The JTEKD18 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. If your contract carries a domestic sourcing clause, this fastener will not satisfy it and you need a domestically produced screw instead.
3) What size driver do I need for the Metallics JTEKD18 hex head screw?
It takes a 5/16 hex driver. The indented hex head measures 0.305 to 0.312 inches across the flats and 0.34 across the corners, which is the standard 5/16 nut driver or magnetic hex bit socket. Head height runs 0.105 to 0.12 inches.
4) Does this screw come with a washer built in, or do I add one?
The washer is integral to the head, no separate washer needed. Outer diameter is 0.384 to 0.414 inches and thickness is 0.019 to 0.031 inches, which spreads the clamp load over sheet metal and duct flange so the head doesn't pull through thin gauge.
5) How tight can I run these screws before I strip them out?
Minimum torsional strength on the Metallics #10 self-drilling screw is 61 lb-in. Set your impact or screwgun clutch so it seats the washer against the panel and stops. Running past that point with an impact is the usual way these snap the head off in thin gauge steel.
6) Are these #10 self-drilling screws okay outdoors or in a damp mechanical room?
The finish is zinc plating over steel, which handles indoor work and normal outdoor exposure on conduit straps, duct and panel mounting. It is not stainless and it is not a coastal or continuously wet spec, so for roof edge, pool rooms or chemical exposure go with a stainless or long-life coated fastener.
7) What thread pitch is a #10 x 1-1/4 self-drilling screw and will it hold in medium gauge steel?
16 threads per inch, made to SAE J78-2013 for self-drilling tapping screws. That pitch is what taps and holds in the 0.035 to 0.110 inch steel range the #2 point drills. Head and body dimensions follow ASME B18.6.3-2010, so it interchanges with other conforming #10 indented hex washer head self-drillers.
8) Is a Type BSD self-drilling screw the right choice, or should I be using a tapping screw with a pilot hole?
Type BSD drills and taps in one pass, so you skip the pilot hole entirely in the 0.035 to 0.110 inch steel range. That is the labor saver on duct runs, strut and enclosure work. If you are fastening into wood, plastic, masonry or steel heavier than 0.110 inches, a drill point screw is the wrong tool, use the fastener matched to that base material.
9) How many screws come in a jar, and what does it weigh?
They ship 100 per jar, one jar minimum, at 0.875 lbs. The jar packaging holds up better in a van or gang box than a bag.
10) Is the steel hard enough to drill its own hole reliably in 16 gauge?
Case hardness runs Rockwell C32-40 on core steel made to AISI 1016-1024, which is what lets the point cut and form threads instead of work-hardening and spinning. Keep steady pressure and a moderate RPM; feathering the trigger is what polishes a point flat.
