Hollow bolt for the accessory idler pulley?

Just bought one to replace alongside my supercharger bearing. The idler is binding a bit too and for $15 or so, I figured why not. It's a flat one, like this - http://cgi.ebay.com/ebaymotors/ws/eB...ht_6511wt_1165

However, since it's such an easy DIY job, I can't find any threads showing how hard the bolt needs to get torqued down. I'm sort of assuming that it might be a hollow bolt (like the supercharger one, IINM), and I don't want to break the thing off.

Any advice?

the bolt isnt hollow but if you have any crank pulley or a c3 i would recommend a pulley saver kit and eliminate the the oem idler altogether

Don't even have a tune yet and at 110K miles, I doubt I'll end up getting one, let alone a pulley; I need Missy here to get me all the way through grad school

It should be torqued to 20nm. It's solid and not the same material, so you don't run the same risk as with the SC bolt, but still.
