Abstract
A blind rivet is provided that is operable for insertion into a workpiece. The blind rivet can include a body portion having a first end and second end. The body portion can include a radial flange formed at the first end and can define a bore extending through the body portion. The rivet can include a mandrel with a mandrel head operable to engage the second end of the body portion. The mandrel head can be larger than the bore and can be coupled to a stem. The stem can be configured to pass through the bore and the flange to enable the body portion to engage the workpiece. The radial flange can also include a plurality of bearing surfaces adapted to be coupled to at least one tool for receipt of a predetermined torsional load at the radial flange to cause failure of the body portion.
