If your Nikon microscope stage isn’t staying in place, you’re not alone. A common culprit? A failed stage screw—specifically, the Nikon part numbers 2K380-348 & MBC91110-A007-2. When the plastic tip on this screw wears out, the stage can start rotating unexpectedly, making it difficult to keep your specimen in focus.

Why Does This Happen?

Over time, the plastic tip on the stage screw becomes worn or damaged, which leads to: 🔬 Stage wobble – Making it hard to get clear images. 🔬 Unstable positioning – The stage won’t stay locked in place. 🔬 Frustration – Difficulty scanning specimens smoothly.
