Often confused with
| Confused with | How to tell them apart |
|---|---|
| C-clamp jaws | C-clamp jaws use a threaded screw mechanism for high clamping force rather than spring-loaded pivot action. |
| Locking plier jaws | Locking pliers use an over-center toggle mechanism that locks in place rather than simple continuous spring tension. |
