When finished checking blind rivets to be checked: the rivet body diameter rivet body rod length, thick cap and a cap diameter, total length of the mandrel, the mandrel exposed size, nut size, as well as the outer diameter of the rivet body after assembly can be considered. In actual testing, we can measure the weak link for the product, such as: tensile strength, shear force, and mandrel anti-de-force. The key is to pay attention to the blind rivet, rivet lack enough, there is no riveted in place; or because the mandrel hat too large to pull the rivet body orifice not go; there jump head that pulled off the mandrel is too low or fracture size is too small and so on.
