I need some rubber grommets, the type which puch into a hole in a panel, take a crush tube and large washers, and are used to isolate components from vibration, usually used with M5 / M6 screws.

Can anyone tell me the correct name so I know what I'm asking for?

Cheers.

Pete.

Look up memfast and they have things called rubber nut, are they what you mean?
