Improved blind rivet

摘要

A space is provided in a mandrel (24) into which rivet sleeve (21) material can be moved to provide after setting a locking of the rivet sleeve (21) to the remaining part of the mandrel (24). This locks the remaining portion of the mandrel head (25) forming resistance to push out, preventing anti-rattle and leads to the elimination of debris prolonging the use of the setting tool.
