Beast Machines Maximal: 
First store appearance: September 2000

Other appearances:  Actually, there are several other Silverbolt characters.  The Aerialbot commander, the bald eagle component of Magnaboss, & of course, his Beast Wars self the Maximal Fuzor.  Of course, this & the BW version are the same person, but whether he is the same or even related to the earlier two 'bolts  is debatable!
