I understand you frustration … fortunatley the screws are very easy to find, use the supplied black screws for the top plate and find 4 M3 CSK 10mm screws of any variety to use in the bottom. Any hardware store will have these, alternatley contact product support and they will ship you some straight away.
this or you mail the djtt shop, they will ship you the rest.
meanwhile you can put it together, by putting the screws at the bottom. the upper party maintains in place with the buttons holding the rest together..
If you haven’t found screws yet, please email us at orders@djtechtools.com and we will be sure to send you a set of screws right away! Sorry for the mixup.
