i was wondering cuz we were messing around with one we found and my boyfriend said to make sure i dont breathe it in. i didnt try to and did and it wasn't much but i was curious if that's why he said not to(he hates people getting high) i wasnt trying to by the way. i'm just curious.
The interconnect signals aren't standard across different manufacturers (and sometimes not even between different models from the same manufacturer). I'd be inclined to just bite the bullet and replace them all with the same model at the same time (then you know they'll work together). The wired interconnect models may never be standardized as it appears most manufacturers are moving towards the wireless interconnects (which probably aren't standardized either). :/
probably a hang over from the Imperial system that doesn't match up with the Metric system or vice-versa. The only nuts I know of that are purposefully made not to match any normal bolts are the ones that secure the welding hose to the Oxygen cylinder of an oxyacetalene gas rig.
They are made that way on purpose. It is so only fittings or fasteners of the same type can only be used with each other.
