A padlock is a common item with a significant purpose. People use them for bikes, outdoor sheds, toolboxes, and gates. Designed to withstand the elements and attempts to damage or cut them, padlocks also have a hidden feature—a small hole on the bottom—that serves an important function.
Serving an Important Function
Padlocks are essential for keeping your belongings safe from theft. Made of metal, they are susceptible to rusting from water damage and extreme weather conditions. The small hole at the bottom of a padlock allows water to escape, preventing rust and prolonging the lock’s life and usability.
Alternative to the Padlock Hole
While the tiny hole in a padlock was once a revolutionary feature, weatherproof padlocks are now available. These designs ensure your belongings remain secure all year round, regardless of the weather.
Another Reason for the Padlock Design
Beyond preventing rust, the small hole on the bottom of a padlock serves another important purpose. If a padlock becomes stuck or won’t open, even with the correct key or code, the hole can be lubricated to help release the lock.
Other Everyday Items with Hidden Features
Padlocks aren’t the only items designed with secret or hidden features. Here are a few other handy objects that serve multiple purposes.
