Where can I find hardware for toddler bed model wm1646 (nuts and bolts package

Just a random guess, have you tried the hardware store?

My experience is hardware stores are pretty terrible when they are larger, but if you go to an ACE hardware or similar, they often have a nice selection of screws, nuts, bolts etc. If you have some like what you need, take them with.

We are FIXYA dot com, we are not Dorel, we just have a Dorel category. You will need to contact them direct for the sticker and the parts

Here is a pdf for a Dorel toddler bed.
It should help you put your one together, even if it isn't exactly the model that you have.
Good Luck

Generation 2 went out of business. Most hardware stores will have the bolts you need
for these beds. The barrel nuts are available at Lowes too.

I have lost the nuts and bolts to put the Carter's convertible crib model #1101CC together. Does anyone know how to get their hands on a set? The bed is no longer for sale.

1-Lower drop side to lower position. Then on the opposite side of the crib, remove stationary side. To remove stationary side, press the small tab on the end hardware(brown plastic piece that connects the rail to the frame) and then pull rail up.
2-Before reinstalling the conversion safety rail(csr), remove the mattress support bolt that is on the side the the csr opening will be(the foot of the bed). A new bolt will be used to reattach the mattress support in the next step.
3-Slide csr hardware onto the hardware on the crib ends. Insert two 1/4-20x2" bolts into each end. One bolt will replace the mattress support removed in step 2. Be sure to put the bolt back through the mattress support bracket before screwing into the end.
