Metallics JTEKD15 – Frequently Asked Questions
1) Are these Metallics drill screws Buy American or ARRA compliant for a government job?
No. The JTEKD15 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your project carries a domestic sourcing requirement, this part will not satisfy it.
2) What driver do I need for the Metallics JTEKD15 hex head screw?
A 1/4 inch hex driver. The head is an indented hex washer head measuring 0.244 to 0.25 inch across the flats, 0.272 across the corners, with a hex drive. A 1/4 inch magnetic nutsetter in an impact or screwgun is what installers use on these.
3) Does the JTEKD15 self-drilling screw need a separate washer?
No. The washer is integral to the head. The built-in washer measures 0.322 to 0.348 inch outside diameter and 0.019 to 0.031 inch thick, which spreads the clamp load over sheet metal and strap without adding a loose part on the job.
4) Is a zinc-plated steel self-drilling screw okay for outdoor or damp locations?
The JTEKD15 is steel with a zinc finish, which is a dry-interior plating. It is intended for electrical, plumbing, and HVAC work inside buildings. For exterior, wet, or corrosive locations, specify a stainless self-drilling screw instead of the zinc-plated steel.
5) What is the thread pitch and torsional strength of the #8 JTEKD15 drill screw?
18 threads per inch on a #8 diameter shank, with a minimum torsional strength of 42 lb-in. That torque figure is the limit to keep in mind if you are driving with an impact driver, since over-torquing is how these snap at the point.
6) What standards does the Metallics JTEKD15 self-drilling screw meet?
Dimensions are to ASME B18.6.3-2010 and threads to SAE J78-2013, with steel per AISI 1016-1024 case hardened to Rockwell C32-40. That combination is what a submittal reviewer looks for on sheet metal drill screws.
7) Is a 1-1/2 inch self-drilling screw too long for attaching a box or strap to metal stud?
The JTEKD15 is a #8 by 1-1/2 inch screw, which is long for thin-gauge attachment where only 0.035 to 0.100 inch of steel is being drilled. The extra length is useful when you are going through a bracket, hanger, or stacked material before reaching the panel. For a flush single-layer sheet metal fix, a shorter length in the same JTEKD series is the better call.
8) Do I need to pre-drill a pilot hole for the Metallics JTEKD15?
No pilot hole. It is a Type BSD self-drilling and tapping screw with a drill point, so it cuts its own hole and forms its own thread in one pass. Drill time runs about 2.5 seconds through a 1 mm plate.
9) How many Metallics JTEKD15 screws come in a jar?
They ship in a jar of 100, which is the order minimum. Jar weight is 0.78 lbs.
