FAQ
Frequently Asked Questions
Vise-Grip is a famous brand name of locking pliers. In the US, 'Vise-Grip' is often used generically (like 'Kleenex' for tissues). Technically, not all locking pliers are Vise-Grips, but the term is frequently understood to mean the same tool.
Their primary advantage is the locking mechanism, which allows them to apply and maintain constant, hands-free pressure. This frees the user's hand, provides immense clamping force, and is excellent for gripping stripped or rounded fasteners.
While designed for temporary clamping, they can be left in place for extended periods. However, for professional, long-term applications, dedicated C-clamps or bar clamps are preferred as they distribute pressure more evenly and are less likely to damage the workpiece.
Usually not. 'Mole grips' is a genericized trademark and is considered informal. In formal UK technical documentation, 'locking pliers' or 'self-locking pliers' would be the preferred descriptive terms, though 'mole wrench' may also appear.
