Design flaw: The *bolt* is designed to take the shearing force. You are

I'm inclined to agree with Nick here. The few times I've made this
mistake myself in the past, the joint has come loose. Sure, there are a
few instances in which it can be okay to load a bolt in shear (a shackle
for example:

but they're cases in which loosening isn't an issue. Mostly it's a bad idea.
