The torque wrench, a seemingly rustic and modest tool, has recently celebrated the 100th anniversary of its existence. It was constructed in 1918 by Conrad Bahr, while working for the New York City Water Department, with the intent of preventing the over-tightening of nuts in the underground water supply systems. Today, the torque wrench is an indispensable tool when it comes to ensuring human safety, from air traffic to Formula 1 races.
