This is why engineers cry.
I feel the pain. It seems that the days of walking into a hardware store and finding the screw you need is over. In the past I remember the hardware guy glancing at a small screw and magically knowing exactly what it was. Now, even if you have a clue to what you need, you cannot find a assortment with what you require. The price of progress I suppose.
That bass bridge is a correct design! You can intonate the strings by moving the saddles back and forth and fixing them with the little screws into position. And you have a propper distance to the twisted part of the strings. In the right picture all the screws that allow moving the saddles in order to intonate were removed! So you cannot intonate the strings at all. And the twisted part of the string is on top of the saddle pieces which is totally wrong. (plus a player might rip of his hands on the sharp ends) And think about the force forward which is on the small height adjustment pins on the left and right side. That bridge was designed for downward pressure not for such pulling force!So what does the engineer say about this? The saddles are held in place pretty much by string tension although they are on a slider.Is the problem in the OP one of not using things as designed and the abuse is prone to failure or is it more of a general design concern?
Me too!Some Ace Hardware stores are still "old school" with an aisle full of drawers of screws, bolts, nuts, washers, etc. It has saved my bacon more than once.

That's how it should look (sorry, by chance that is a lefthanded guitar):
