Bolt depot carries a large selection of metric hardware and it's not to hard to put a point on a socket head cap screw.(allen bolt) Try them at www.boltdepot.com

The problem is to determine what thread is the broken bolt?
If you have a set of metric taps it will make your search much easier.

The Ace Hardware Stores also have a nice assortment of american and metric hardware.

the bolt is an 8mm 1.25mm TP and its approximately 40mm long full thread.
