Metallics JTMS86 – Frequently Asked Questions
1) Will a machine screw like the JTMS86 thread into sheet metal on its own?
No. The JTMS86 is a machine screw, not a self-tapping or self-drilling screw. It needs a pre-tapped 5/16-18 hole or a matching 5/16-18 nut to pull against. If you're fastening into untapped sheet metal, you need a sheet metal or self-drilling screw instead, or you need to tap the hole first.
2) Why would I pick a truss head screw instead of a round or pan head?
A truss head is wide and low profile, so it spreads bearing surface over a larger area and sits closer to flush. That is why it gets used on sheet metal, enclosure covers, and oversized or slotted holes where a pan head would pull through or stand too tall. The JTMS86 pairs that head with a slotted drive, so a standard flat blade screwdriver works, no bit change needed.
3) Is the Metallics JTMS86 screw zinc plated for corrosion resistance?
Yes, it's steel with a zinc plating (St-Zn in the description). Zinc plating handles dry indoor and protected service, which covers most panel, box, and enclosure work. For sustained wet, washdown, or exterior exposure, go to stainless steel instead.
4) Does a nut come with the Metallics JTMS86 screws?
No nuts or washers are included, the jar is screws only, 100 pieces of the 5/16-18 x 2 truss head. If the hole isn't tapped, order 5/16-18 nuts separately, and add flat washers if the hole is oversized beyond what the truss head covers.
