Good advice no matter what fastener you use!A tiny bit of grease - any grease - on the thread will help the nut nip up tighter.
I recently found myself getting very frustrated with a chain splitter that didn't work as it used to. After half an hour and a hand full of scraped knuckles I realised the problem. A squirt of oil to the thread of the tool and it was working again with minimum effort.
Lesson learnt: Never underestimate the friction generated by a poorly lubed thread.
