A padlock is a common object with a very important use. They are used by people for gates, toolboxes, bicycle storage, and outdoor sheds.
They are made to resist cuts and other attempts to harm them from the environment. They do, however, contain a hidden feature—a little hole on the bottom—that has a very important function.
Serving an Important Function
Padlocks are small but powerful metal tools used to prevent theft. However, they are vulnerable to rust and damage caused by weather extremes and water. Fortunately, padlocks have a secret hole on the bottom that allows water to escape, preventing rust and extending their lifespan.
Alternative to the Padlock Hole
While the hole on padlocks is a revolutionary feature, there are now waterproof padlocks available in the market. These waterproof padlocks ensure that your belongings remain safe and secure throughout the year.
Another Reason for the Padlock Design
The little hole on the bottom of a padlock serves another purpose besides preventing rust. In some cases, even with the correct code or key, a padlock may become stuck or difficult to open. In such instances, a synthetic lubricant can be applied through the hole to facilitate opening the padlock.
