Finding the right size nut

[ppppenguin]

Thanks for the reminder about coach bolts. I remembered I had some M10 coach bolts andmanaged to find them. A nut from one of them (it was hex rather than square) does fit the dowel screws. Doesn't run 100% smoothly but that's due to minor damage to the dowel screw rather than M10 being the wrong size.

Problem solved. Until I need some coach bolts and find the nuts are missing
