What tool is specifically used to dress bruised or rusted threads?

• A. Thread chaser
• B. Dyes
• C. Threads cutter
• D. Dies

Answer: (D)

The correct choice, which is dies, is used to dress bruised or rusted threads effectively. Dies are cutting tools that can reshape and restore the external threads on a bolt or similar component. When threads become damaged due to rust, wear, or accidental impacts, using a die allows for the re-cutting of these threads to the correct profile and pitch, making it easier to fit the fastener back onto a corresponding nut or threaded hole. In comparison, other tools mentioned, such as thread chasers, dyes, and thread cutters, serve different purposes. Thread chasers are generally used in more specialized machining operations, dye is typically referenced in non-metallic applications regarding color, and thread cutters usually refer to tools used to make threads from a solid material rather than dressing existing threads. Therefore, dies are uniquely suited for the task of fixing bruised or rusted threads in metalworking applications.
