Metallics JTEKDF35 – Frequently Asked Questions
1) Is the JTEKDF35 a self-drilling screw, and does it need a pilot hole?
It is a self-drilling screw with a #3 drill point, so it cuts its own hole in metal without pre-drilling. The #3 point is the heavier of the common self-drill points and is intended for thicker gauge steel than a #2 point handles.
2) Will a zinc plated screw like the JTEKDF35 hold up outdoors?
The JTEKDF35 is steel with a zinc plating, which is a dry-location and general indoor finish. Zinc plating gives mild corrosion resistance but is not a marine or sustained-wet-exposure coating. For exterior, damp, or coastal work, specify stainless or a hot dip galvanized fastener instead.
3) What is this self-drilling screw used for on electrical work?
It is an electrical-trade fastener, used for anchoring strut, straps, boxes, panel mounting plates, raceway, and bracketry to steel members and studs. The 1-1/4 inch length leaves enough shank to pass through a mounting flange and still get full thread engagement in the steel behind it.
4) Can I use the JTEKDF35 in wood or drywall instead of metal?
It will drive into wood, but it is not the right choice. A #3 self-drill point is made to cut steel, and in wood the point and the aggressive thread can strip or split rather than hold. Use a wood screw or a drywall screw for those substrates and save the self-drillers for metal.
5) How does the Metallics JTEKDF35 screw come packaged?
It ships in a jar of 100 screws. The jar pack is handy on a service cart or in a van bin, since it reseals and does not spill the way a bagged count does.
