So I recently bought an older Halo 2 that was missing a screw.  I wasn't too worried about it but the seller said they had a case open for a replacement and wouldn't you know Microtech actually came through with a new matching screw.  I went to replace it and found it appeared the old screw had broken in half.  Took most of the threading with it.  I proceeded to take it apart in an attempt to at least remove the bottom half with my left threaded drill bit set.  Of course, the set didn't have the smallest size possible so going to have to wait on amazon for that bit. 

My main issue is during disassembly I found three other screws similarly afflicted with the same issue.  Now as this will have a place of honor among my display I am fine putting things back as they were (not my first choice of course).  But it makes me ask, is there an issue past or present with screw metallurgy used in the Microtechs.  I will say I've also found issues with a recently manufactured Ultratech's screws as well.

Anyone else have these troubles pop up?

I've taken apart a few Halos and a butt ton of (mostly older) Ultratechs.  I've never seen a broken screw as you describe, but I've come across a heck of a lot of stripped ones that were simply "glued" in with loctite.  I can think of at least two UTs I took apart where three of the six screws were essentially decorative because of this.

Conversely, I've been surprised at the strength of the original (small) UT screws.  Had one once I was using as a parts donor that had one screw stuck (possibly cross-threaded + an ample amount of red loctite).  Instead of drilling it out, I figured I'd just rip the top away from the bottom; I ended up deforming both halves significantly.

I had the same issue when I took my UT apart. Screw was fine the threads were stripped. Aluminum is not the best material for tapping threads. Especially when the threads are tiny.

I am going to do my best to pull the broken bits out with a reverse drill bit but it may be too fine a job for me and go off to a jeweler for that.  I know what you mean about stripping the threads.  The screws were never meant to be very tight and should always be installed with a dab of loctite, something most who tinker with them don't know.
