I recently put up shelving using wall studs as support. I used an
electronic stud finder, then of course made sure the screws went into
the stud and not the wall. However, I just found out about the magnet
test and it indeed is helping me find an additional stud a lot easier
than the stud finder did. However...

For the 12 x 36" shelf I already installed, the magnet test is not
finding a stud where I had installed one of the shelving brackets, but
about 3-4" to the right of the bracket, yet I know both screws for that
bracket went into a stud. There are no wires or outlets near this
section of the wall. Can studs sometimes be only 3-4" apart for some
reason with one stud having no nails driven into it for the drywall
installation? How can I tell for sure? Could it be anything else
holding that shelf bracket?
Thanks!


plumbing, plumbing vent, central vac, HVAC, etc etc
... an extra stud put in by the carpenters because the first stud
was compromised by plumber, electrician, HVAC, etc etc
Structure on the other side of the mystery stud that needed it ?
Drywallers would just use the normal stud location.
