Why Is There a Tiny Hole on the Bottom of a Padlock?
At first glance, this little opening might seem random or decorative. But in reality, it serves a very important purpose—and knowing what it does can help you make your padlocks last longer and work better.
In this article, we’ll explore why that hole exists, how it protects your lock, and what else it can be used for.
The Hidden Purpose Behind That Tiny Hole on Your Padlock
Although it’s small, that hole is part of a smart design that solves a big problem: moisture.
1. A Built-In Drainage System
Padlocks are often used outdoors, where they’re exposed to:
- Rain
- Snow
- Humidity
- Sprinklers
- Condensation
Over time, water can seep inside the lock’s internal components. If it has nowhere to go, it settles inside—leading to internal rust, corrosion, and eventually lock failure.
