We used those Rivnuts at APC to attach to aluminum heatsinks.  Automatic feed, 
self tapping (actually more like forming) on the production line, yet 
repairable.  Many versions have a conical head so it is like having a Belleville 
washer in there, which is great for an electrical connection.

Tiny little suckers, aren't they?  Actually a lot of engineering went into their 
design.
