What is a device used to hold or fasten objects securely during work called?

A device used to hold or fasten objects securely during work is appropriately called clamping tools. Clamping tools are specifically designed to exert pressure on an object to keep it in place, making them essential for a variety of tasks such as woodworking, metalworking, or any scenario where stability is required while working on a project. They help ensure precision and safety by preventing movement, allowing the user to focus on the task at hand without worrying about the workpiece shifting unexpectedly.

The other categories are distinct in their functions: power tools refer to electrically or mechanically operated tools that assist in cutting, drilling, or driving, while hand tools encompass tools that require manual operation, such as hammers and screwdrivers. Measurement tools are used to ascertain dimensions or specifications but do not involve the functions of holding or fastening. This distinction clarifies why clamping tools are the most suitable and correct answer in this context.
