These are the typical size grub screws used in most RTAs. I use them to replace screws that are slotted or philips head since these hex heads are easy to tighten and won’t strip. These are longer than the usual with the idea that more threads engaged means that they tighten better and won’t wear out the rta threads as much. With most normal wire and fused claptons the screws don’t protrude, but if you’re going to fill the hole with massive wire then these maybe too long.
