Bare with me this is my first time installing a case for any keyboard.
So last weekend my Acrylic case from MD came in and I got around to installing it today. As I tried to screw in the screws I noticed that they didn't fit and were missing the threadings. Are these screw threads suppose to come in with the Massdrop package or am I suppose to buy them separately?
First off, what case is it?
There are three different ways that screws are handled on acrylic parts:
1. Unthreaded holes with tightly threaded (machine) screws:

Like the Tex Poker style case. On these, the screws make the thread the first time you use them. Be careful as it's pretty easy to strip the newly created thread by overtightening. The Tex case uses standard Poker II screws.
2. Metal thread inserts glued in or held by friction:

3. Through bolts with nuts:

Once we know what case you have, we can advise you further.
