Re: Blind pop rivet tensile strength

Your interpretation of the loading is correct.

The numbers given are static load ratings, meaning that "if I hang 500 lbs from this rivet, it will exceed its rating and fail." However, FRC loads are nearly always dynamic or cyclical in nature to some degree. This means that they repeat themselves. It is my understanding that this kind of cyclic loading is likely to work a rivet loose over time when applied in tension, since it will pull on the deformed flange and loosen it some. It'll take a lot of force to fail a rivet in tension outright, but it can easily loosen to the point of not being very useful, as your pieces will no longer be firmly held together.
