I'm planning on mounting an oak DVD rack on my wall, 3 studs wide - about
36" assuming 18" centers. This is just guesswork for now so the numbers
aren't that important. Anyway, so I'm going to hang a single shelf 36" oak
DVD rack, assume it will be filled with DVD's. The plan is to mount it
directly to the studs, but that's not something I can necessarily count on
in case I move the rack in the future. So I'm wondering whether or not
drywall will be able to hold that much weight if I use drywall anchors. I
actually don't know how much it will weigh I'm guessing less than 50 lbs.
IMO molly toggles & molly bolts suck.
They're a PITA to work with, I hatethem, never use them.
I think your weight estimate (< 50 lbs) is good. SO even if you only
use three screws the withdrawl load on the center screw (worst case)
is less than 25 lbs.
I would use plastic wall anchors, I know they're not all that strong
but the loads in your situation are pretty low.
use threaded drywall anchors (plastic or zinc); quick, easy, strong
Mollys are overkill for you application; too much work & harder to
remove & patch
Plastic anchors are indeed made of "cheap slippery plastic"
but they do not easy slip out of drywall IF the correct drill size is
used AND the correct screw size is used.
Correctly installed, the anchor spreads & grips the drywall...never
had pull out problem with them as long as the loads were reasonable.
I've never actually used a moly bolt. I can see how they'd be a bear to
patch and use, but my experience with plastic anchors is pretty ugly. I can
try what you have there, also perhaps may try those drywall toggles - they
seem a bit more solid - but probably won't work as well if there's
insulation behind the wall.
I know it's not a lot of weight per screw - I'm thinking 4 holes myself - so
that's less than 15 lbs per hole
If you take care to drill the right size hole with a new bit, insert the
insert flush with the wall, and use the right size screw in the insert (with
enough penetration), they hold well. You have to go by the numbers, though,
but if done right they are pretty sturdy.

You would actually use a new bit in plaster? Doesn't that dull bits
faster than almost anything else?
I use the bits I paid 69 cents for 14 of them, and I don't think my
hole is any different in diameter or smoothness than any other bit
Plastic wall anchors may be cheap, but that's because plastic is cheap
and anchors are easy to make.
They may be slippery, but they have little teeth that imbed themselves
in the plaster and the question is whether those teeth are sufficient
and whether they loose their corners so easily that the anchors slide
out. I don't think they do at low weights, but I've never weighed
things or compared them with the promised capacity so I don't know.
I don't know why the OP is asking about the NEXT time he hangs this
shelf, when he says that this time, he is putting the screws in studs.
I also don't know why it can't always be mounted on studs, since the
screws don't have to go through at the ends of the rack. If the rack
is 36 inches wide and 16" spacking, the left screw can go through the
rack say 8 inches from the left end, the next screw aat 24 inches from
the left end (and 12 from the right), and that is 16 inch spacing.
If there are holes from the previous mounting, one can put screws in
those too, even if those screws don't hit the studs and might bear no
What's so hard?
1. Drill bolt size holes in whatever you are going to put up.
2. Temporarily put against wall and use bolt holes to mark/drill holes
3. Drill holes in DW the diameter of the molly insert
4. Insert mollys
5. Tighten bolt so molly expands behind wall and the collar flange
sets slightly into DW
6. Remove bolts
7. Put bolts through what you want to hang. A washer under the head
may be needed depending on how big a hole you drilled.
8. Screw bolts into molly inserts
If you ever remove your shelf all you need do is swipe a bit of
spackle or DW compound over the sunken collar of the molly. Easier
than fixing a hole from a plastic insert, lots easier than fixing a
large hole from a toggle bolt or the big threaded DW anchors.
