The plastic "fit in hole" shelf-supports come out too easily, with the
result that if someone bumps it,the shelf falls out, along with
everything on it.
Each support works by pushing (inserting) its 1/3-inch-long cylinder
part into the predrilled hole; four such holes, each with one of these
plastic inserts, support the four corners of a shelf.
One way to keep a support from slipping out of its hole would
be to glue the cylinder part into the hole.
Disadvantage: you can never get it out again, should you
want to change the spacing between the shelves.
Question: is there some kind of a WEAK glue that will hold up to a
point, but then will break its bond, allowing you to remove the
I've used wood dowels in place of the plastic supports and they worked
fine....they would have to shear in order to break. Wood dowel, tight
enough and long enough, will support a shelf full of books without
problems. If the sides of the bookshelf shift, that's a separate
problem.....has it got a solidly fastened back? If not, put in some
sort of back or brace.
There are actually made metal "shelf pins" for just this purpose. If
you have a good hardware store they ought to have them. However if they
fit loosely maybe a little contact cement or something might be in order.
replace "roosters" with "cox" to reply.
If they don't know what "shelf pins" are, you are in the wrong store...it is
a standard, generic term.
Basically, two types:
a) round with a flat at one end
b) round with an "L", "L" supports the shelf

Home Depot and Lowes carry them. Look in the hardware section in the
drawers that hold specialty stuff like automotive parts and stainless.
There should be a few drawers marked "furniture parts", or some such.
Take a peek through there. There're some interesting widgets that may
be useful for future tasks.
They're in small quantities and therefore expensive, so if there is a
woodworking store in the area you can always find them there. If you
want to order online there's Woodcraft or Rockler.

Tape worked great. I just cut thin strips - crossways, same with as the length of the pin - off the end of a roll of masking tape. I then wrapped 3 or 4 around the pin, one at time. The pins fit snuggly into the holes.
Simple, good idea. All done in a few minutes.
If the supports are the kind that have a metal or plastic "L" on the pin
then your shelves are too short. They should be long enough so that the
support pins *cannot* come out.
If they are just cylindical pins you can make the hole smaller - think "flat
toothpick" - or the pin larger. You could make it larger by putting on a
dab of cyanoacrylate (instant glue) and letting it dry before inserting.
When you can't smell it, it is dry.

Yes. Ambroid Cement is what I use when I want a glue I can break
later. It also has a lot of other advantages. It sticks to most
things and dries quickly. A tube will last until you've finished it.
If you put the cap on firmly, it will not harden in the tube. I
boughgt two large tubes once, because they were all beat up and were
for sale cheap, and the second one was 20 years old when I finally
used the last of it.
But it's not sold in hardware stores or HD. You have to go to a hobby
store, and at the hobby store, it seemed expensive, so I only bought
the small tube. But I use it for lots of things so I should have
bought the big one.
Even with this stuff, I would try one pin first, although I don't know
why. I'm sure it will break from the plastic. It may not break from
the particle board, or worse yet, it may take too much board with it
when it does, if the cohesion of the board is less than the adhesion
of the glue to the board and the glue to the plastic.
You can also buy some rectangular (not round) tooth picks and use
slivers from the picks to get the supports to go in more tightly.
Or you could shim the joint by finding a plastic straw of the
appropriate diameter, then snipping off a sleeve for each
of the shelf supports, so that it fits finger-right. This avoids messing
