What did the cross section of the broken bolt look like??? Less than 2% of fastener failures are from shear forces......However, over 88% are from Fatigue failures.... which will yield a relatively smooth failure face, normally with "beachmarks" on it...like the lines on a beach from the waves...
I've been involved with fasteners for 35 years, including presenting over 350 fastener seminars to mechanics & engineers......
I didn't really look at it that closely, so I have no idea. It was broken below the collar on the threaded part, though. The bolts I just bought are longer to make sure the collar takes the force and not the threads.
Is there a way to turn the gear without moving the slideout section? That sure would make it easier to line up the bolt holes with the square tubing rather than having to have someone inside bumping the motor switch until it lines up.
