In the early 1930s, aircraft maintenance changed forever with the invention of the Dzus fastener. Ukrainian-born toolmaker William Dzus grew frustrated with the maze of latches, screws, buckles, and pins that plagued aircraft of the day, so he designed something better. Pronounced like the Greek god “Zeus,” his invention required just a quarter turn to secure or release the metal panels that keep warbirds accessible and airworthy. Our mechanics, "The Gregs," are very thankful for his ingenuity.
