Mustool Microscope Vertical Groove Slide

The screw for adjusting the vertical slide on the Mustool microscope kept spinning and wouldn't tighten. Turns out metal screw in plastic thread had done the usual trick and stripped it. This is another one you just slide in and away you go.

Before you put it in, spend a little time working the screw into the thread in the hole to start it off gently. A bit in, a bit out, a bit more in, and a bit out etc until it goes all the way through.

Then unscrew it, slide it into the groove, align with hold on vertical carriage and you're finished.
