Expanding Cam Handles for Unthreaded Holes

Use these handles to keep holes aligned or lift several sheets of thin material. They have a plug that expands to grip the edges inside holes. They are not suitable for permanent installation—use only for temporary mounting. Made of plastic, all of these handles resist oil, grease, and solvents.
