Thomas,

The bolts did not come from Dywer, they came from McMaster-Carr.  I don't have an actual recollection, but the video says that one was 1.5" and the other 2.5".  They were labeled as 'button head'; a rounded head with a hex indentation for an Allen wrench.  This is discussed in the video at about 7:45.
