This is actually a two part question. The background is the hinge on my laptop broke. Initially it was attached by 3 screws to brass threaded inserts that had been molded into the plastic laptop lid. Due to the stiffness of the hinge and probably also due to me opening it improperly (from one side instead of both sides or the center), the inserts broke out of the plastic, leaving three housings where they were originally set. See here: [url]http://i.imgur.com/4sNabed.jpg[/url] 1) If I purchase some inserts to replace them, will JB Weld work to attach the brass inserts to the plastic housings? Is there some other adhesive that would work better? I have 5 minute epoxy at home, and could buy something else if it was better. 2) Which kind of inserts would be best to buy to replace them? Should I use something like these heat-set inserts [url=http://www.mcmaster.com/#standard-threaded-inserts/=r2z9zt]McMaster-Carr[/url] that are pretty much identical to the originals, despite not using heat to set them (or I guess I could use a soldering iron to heat them up, but I don't know if the fit would be tight enough to melt and set the plastic over them...)? Would helical inserts like these [url=http://www.mcmaster.com/#standard-threaded-inserts/=r2zatt]McMaster-Carr[/url] be best? Is there another option I'm missing? All suggestions welcome. Thanks!

My highly hormonal daughter is torturing me (mentally) because I lost some of the crib bolts...... They are bronze, the length (50mm) and I think its a M6 - I dont know what the M6 indicates but A big box store carries M4. If I order them online they will not arrive before the baby, my daughter has the remaining bolts and live 2 hours away..... Questions: 1) I dont think M4 & M6 are interchangeable but ARE THEY? 2) Any ideas where I can find these?
