Which term is described as a tool used to undo screws with a hexagonal socket?

• A. Allen key
• B. Panel pins
• C. Cam bolt
• D. Nut and bolt

Answer: (A)

The tool that fits and turns screws with a hexagonal socket is an Allen key. It has a hexagonal cross-section that matches the recessed shape inside hex socket screws, so when you insert it and twist, the tool grips the screw firmly and allows you to undo or tighten it without stripping the head. An Allen key is often L-shaped, giving you good leverage in tight spaces. The other terms refer to things that aren’t tools for turning hex screws: panel pins are small nails used to fix panels; a cam bolt is a type of fastener with a cam mechanism; and a nut and bolt pair is a fastening system, not a tool.
