Metallics JTMSP142 – Frequently Asked Questions
1) Will a 3 inch long 6-32 screw work for mounting a device in a deeply recessed or mudded-over box?
That is the reason to reach for this one. At 3 inches, the JTMSP142 6-32 truss head screw spans far more depth than the 1 inch screws that ship with a device, so it reaches the tapped ears of a box set back behind thick drywall, tile, stacked mud rings, or a built-out wall surface. Thread engagement is the same 6-32 as the factory screw, so nothing else about the device mounting changes.
2) Are these Metallics 6-32 screws steel or stainless, and are they coated for corrosion?
Carbon steel with a zinc plating. Zinc plated steel is fine for dry interior work, indoor boxes, panels, and enclosures. For damp, exterior, or washdown locations, specify a stainless fastener instead, since zinc plating is a sacrificial coating and not a substitute for stainless in wet duty.
3) Is the JTMSP142 a sheet metal screw or a machine screw?
Machine screw. The MS in the Metallics description means machine screw, so it has a blunt, uniform 6-32 thread meant for a pre-tapped hole or a nut. It will not self-start in plain sheet metal or wood the way a sheet metal or tapping screw does, so drill and tap, or back it with a 6-32 nut.
4) What is the manufacturer part number to order these 6-32 x 3 truss head screws?
Metallics part number JTMSP142. One part number covers the whole item: 6-32 x 3 inch, truss head, combo drive, zinc plated steel, 100 to a jar.
5) What is a truss head screw and does it sit flatter than a pan head?
A truss head is wide and low, with a larger bearing surface and a lower profile than a pan head. On the JTMSP142 that matters when the screw lands on an oversized or slotted hole, or on thin sheet metal, because the broader head bridges the opening and keeps the head from pulling through or standing proud under a cover plate.
6) How many screws come in a jar of Metallics JTMSP142?
100 screws per jar. The jar pack is the shop and truck-stock format, so the whole 100 count comes as one container rather than loose or bagged counts.
7) Can I cut a 3 inch 6-32 truss screw down to length on the job?
Yes, it's a straightforward machine screw thread running its length, so a 3 inch 6-32 can be cut back with a cutter and the end cleaned up to restore the thread lead. Many electricians buy the long version for exactly this reason, carrying one jar rather than several lengths.
