These hose clamps are 316 SS throughout including the worm gear which is always the starting point for rust and corrosion.
Low quality hose clamps are a major reason boats sink. Have you ever removed a hose clamp and with shock realized that the damned thig wasn't really holding?...enough said.
These clamps require a 7mm hex wrench. We suggest the ABA unit which we also have available here. Product ABA01
