Air-Powered Squeeze Tools for Solid Rivets

Compressed air provides nearly double the force of manual tools. These tools are also known as alligator squeezers.

A die set (sold separately) is required and must be attached to the tool jaws to properly form rivets during installation. Choose a die set that matches the rivet's head style.
