Metallics JTMS33 – Frequently Asked Questions
1) Will a 10-32 x 1/2 inch truss head screw thread into a standard steel outlet box?
Yes. 10-32 is the thread used in the tapped holes of standard steel outlet, switch and junction boxes, so the JTMS33 threads straight into box ears and ground screw holes. The 1/2 inch length suits mounting devices, brackets and plates directly to the box without bottoming out.
2) Why use a truss head screw instead of a round or pan head on electrical work?
A truss head is wide and low profile, so it spans an oversized or slotted hole and holds thin material or a bracket flat without the head standing proud. That makes the JTMS33 useful where a pan or round head would either pull through a large hole or interfere with a device or plate sitting over it. The drive is slotted, so a standard flat blade screwdriver works.
3) Are these zinc plated steel screws OK for damp or outdoor locations?
The JTMS33 is zinc plated steel, which is a mild corrosion coating meant for dry indoor use. For wet, outdoor or corrosive locations, specify a stainless steel machine screw in the same 10-32 x 1/2 size instead, since zinc plating on steel will eventually rust in standing moisture.
4) Is a machine screw like the JTMS33 the right choice for fastening into drywall or wood?
No. A 10-32 machine screw needs a mating tapped hole or a nut, so it is for metal boxes, brackets and pre-threaded holes. For drywall or wood you need a sheet metal, wood or self-drilling screw instead. The JTMS33 is a machine screw and will spin freely in an untapped hole.
5) How are the Metallics JTMS33 screws packaged, and how many come in one?
They ship in a jar of 100. The jar pack is what electricians and MRO stockrooms usually want on the truck or shelf for a consumable like this, since you can pour out a handful and reclose it rather than dealing with a loose bag.
