Which hand tool uses a locking mechanism to hold objects securely?

• A. Channel Locks
• B. Vise Grips
• C. Torque Wrench
• D. Torx Screwdriver

Answer: (B)

Locking pliers, commonly known as Vise Grips, are designed to grip and hold objects securely with a built-in locking mechanism. The jaws can be adjusted with a screw at the end of the handle to set the desired grip force. When you squeeze the handles, the jaws clamp shut and latch into place, letting you maintain a firm hold without continuous squeezing. A release lever near the pivot frees the lock so the tool can be opened.

This locking feature is what sets them apart from the other tools listed. Channel locks are adjustable pliers that grip but don’t lock in place, so you must keep applying pressure to maintain the grip. A torque wrench is used to tighten fasteners to a specific torque and isn’t intended to hold objects in place. A Torx screwdriver is a driver for Torx fasteners and does not provide a locking grip on objects.
