The mounting studs in an MH box are different or equal to the mounting studs in an HC box.

Resolution:
For NQOD and NF, the mounting studs are installed in the box as part of the manufacturing process (pierce form) and are not replaceable. I-line and QMB box studs are installed from the back and are held with keeper nuts. I-Line and QMB box studs are replaceable.
