1/260 ST:TMP Drydock Part 1
Light Panel Frame Connectors - 2
If you watch the close up shots of the dock in TMP you can see these dome nuts holding the frames together. So I can keep track of how many Dome nuts were used I put two on each of the threaded rods to keep count and make sure I have the right amount. They are 3mm nuts so they can get lost quite easily.
