Tiny Screwdriver!

My buddy dBm took pity on my plight:

The far end has a 2.5 mm hex driver, although I’ve never encountered a nut for an M1×0.25 screw in the wild. It doesn’t fit an 0-80 nut and gulps 00-90 nuts, so it’s definitely hard metric.

My collection of glasses required an aggregate two turns of tightening, which prompted dBm to remind me of threadlock.

Done!

Thank you, dBm!
