Then youve seen a bunch of **** screwed together by morons. Bolts can carry (small) load in shear depending on the material and the fit (friction) between parts but they are designed really for carrying a load in tension and should be used as such. Keys and keyways are a much better way of mechanical power transmission.

Normally I agree with you, but you're just flat wrong.

Notice: Not a keyway in sight....only bolts...

But yeah, Blower Drive Service doesn't know what they're doing.



(Hint: if the bolt is carrying load in shear, then it's lost tension for whatever reason. When a bolt is properly tensioned {a.k.a. tight}, then it sees virtually zero shear load in these applications.)

I will agree that keys can carry enough load to get the job done if you add a whole bunch of them, and call them....
splines.
