Which tool can be used as clamps or for tightening and loosening nuts and bolts?

• A. Mole grips (parrot nose pliers)
• B. Belt Sander
• C. Machine vice
• D. Scroll Saw

Answer: (A)

Tools that combine a locking mechanism with adjustable jaws can act as both a clamp and a wrench-like grip for fasteners. Locking pliers, often known as Mole grips, have an adjustable screw to set the jaw width and a catch that locks the jaws in place. This lets you clamp a workpiece securely, and the jaws can grip the head or flats of a nut or bolt so you can twist it to tighten or loosen it, even in confined spaces where a normal spanner won’t fit. The other tools don’t fit that dual role: a belt sander is for smoothing surfaces, a machine vice is a fixed clamp used on a workbench for machining but not for turning fasteners, and a scroll saw is for cutting shapes.
