For the record, they are indeed 7mm.

For those that mentioned trouble finding this size, Home Depot carries a set
of 3/8" socket drive 4/5/6/7/8/10mm hex keys for CDN$20. Wal-Mart has a set
of 15 each SAE & Metric standard Allen Keys, including 7mm, for CDN$10, if
you don't care about torquing to spec.
