I bought a set of drawers from INDEX and when I was assembling it, 4 cam
bolts broke (or cam dowels whatever). INDEX says purchase locally and
I'll be credited with the cost.

Okay, does anyone know where I'm going to get these cam bolts? They are
the type that screws into a (plastic) nut, not directly into wood.

Also, I would have thought INDEX ought to have been able to tell me the
maniufacturer of the drawers I bought. TIA.
