Metallics JTEKD18V – Frequently Asked Questions
1) What metal thickness can the Metallics JTEKD18V self-drilling screw drill through?
The #2 drill point on the JTEKD18V is rated for panel thickness of 0.035 to 0.110 in. That covers typical light-gauge steel studs, strut, and sheet metal enclosures. Thicker structural steel is outside its range, so pick a heavier drill point for that.
2) Do I need to pre-drill or tap for the Metallics JTEKD18V screw?
No. It is a Type BSD self-drilling and tapping screw, so the drill point cuts the hole and the threads form their own mating thread in one pass. No pilot hole, no tapping.
3) Is the Metallics JTEKD18V screw Buy American compliant for a government or public-works job?
It is flagged both ARRA compliant and Buy American compliant, with country of origin listed as multiple. For a federally funded spec, cite those compliance flags along with the applicable standards it is built to: ASME B18.6.3-2010 dimensionally and SAE J78-2013 for threads.
4) What driver or socket fits the JTEKD18V hex head screw?
It takes a 5/16 in. hex driver. The indented hex head measures 0.305 to 0.312 in. across the flats and 0.34 in. across corners, with a head height of 0.105 to 0.12 in. A standard 5/16 magnetic nut setter in an impact or screwgun drives it.
5) Does the JTEKD18V come with a built-in washer, or do I buy washers separately?
The washer is integral to the head, so nothing extra to order. Washer outside diameter runs 0.384 to 0.414 in. with a thickness of 0.019 to 0.031 in., which spreads the clamp load on sheet metal and thin panels and resists pull-through better than a plain hex head.
6) How many screws come in a jar of Metallics JTEKD18V, and is there an order minimum?
They ship in a jar at a 500-count order minimum, so a single buy gets you 500 screws. Jar weight is listed at 4.45 lbs.
7) Will the JTEKD18V zinc-plated screw hold up outdoors or in a damp location?
The JTEKD18V is carbon steel with a zinc finish, which is a dry-interior or protected-location fastener. For exterior, wet, or corrosive runs, use a stainless self-drilling screw instead; zinc plating will eventually corrode in those conditions.
8) What thread does the #10 Metallics JTEKD18V screw have, and will it strip out in light-gauge steel?
It is a #10 with 16 threads per inch, UNC form. Torsional strength is 61 lb-in minimum and the screw is heat treated to Rockwell C32-40, so the point stays hard enough to cut while the body resists snapping. Set your impact or screwgun clutch rather than running it to stall and you will not shear heads or strip thin panel.
9) Is a 1-1/4 in. self-drilling screw long enough for my application?
The JTEKD18V is a #10 x 1-1/4 in. screw. Subtract the panel you are drilling into (0.035 to 0.110 in. of its rated range) and you still have over an inch of grip length, so it handles stacking a bracket, clip, or strap onto light-gauge steel. For thicker assemblies or deeper standoffs, step up to a longer screw in the same series.
10) What steel is the Metallics JTEKD18V made from?
Carbon steel per AISI 1016-1024, case hardened to Rockwell C32-40 and zinc plated. That is the standard material range for self-drilling tapping screws and it is what lets the point cut steel without rolling over.
