[sdiy] Circuit board posts/spacers?

[ian taylor]

I have a couple of motm distribution boards that I need to mount inside my cab, and I want them raised an inch or so away from the surface they are going on to,
but I don't know what the correct terminology is for the posts or spacers I need, (standoffs? risers? etc...) 
The guy in Maplins looked at me strangely and announced they don't do anything like that.
I can't see why these aren't a pretty standard thing - can any of you tell me what to call them, or better still where I can find some? Cheers!
