Ajolives Thanks for the measurement. I think the 58mm should work also given the spring is radially wounded so that last strip shouldn't be able to get onto the other edge of the washer when the rest of the spring is covered. What do you think given you have the actual gear and spring to make the evaluation?

I couldn't find anything thinner than this one at 6mm unless maybe go custom. I found a titanium one that's 20mm thick actually, haha. Maybe other member that has connection with a machine shop can work or look for some solution?

Were we able to confirm that the bolt does or doesn't have a washer attached already? If it doesn't, then maybe the 6mm thickness doesn't matter?
