KS Dropper post set screw

Ransaka

Had an issue and have lost the little set screw that holds the cable near the actuator on the remote version but can't recall what size they are and forgot to measure the hole before I left for work. Does anyone happen to know off hand? Found the actual item in the US stockists but it doesn't list the size of it and I'm not paying 25 dollars to have a tiny screw shipped
