Look again, Chris. The right end of the pin is threaded into the clevis. That does not forgive the obvious error of incorrect fastening. The clevis should be straddling the angle, with the pin through it all. On top of that, as soon as the load is applied, that angle will be placing a side stress on the bolt. In no way is this rigged anywhere correctly. What we do not know is what the overall load is, as the pic doesn't show that.
