What Is That Little Hole at the Bottom of a Padlock For?
If you’ve ever looked closely at a padlock, you might have noticed a tiny hole at the bottom and wondered, “What’s that for?” It’s a small detail that many people overlook, but it actually serves some very practical and important purposes.
Let’s uncover the mystery behind the little hole at the bottom of a padlock and why it’s there!
🔐 The Drainage Hole: Why Does It Exist?
The little hole you see on the underside of many padlocks is called a drainage hole. Its main job is to:
Allow water to escape from inside the lock.
Prevent rust and corrosion caused by trapped moisture.
Keep the lock mechanism working smoothly over time.
💧 How Does Moisture Get Inside?
When a padlock is used outdoors or in humid conditions, rain, snow, or even morning dew can seep into the lock’s body. Without a drainage hole, this moisture would stay trapped inside, leading to:
Rusted internal components.
