The hole itself is small, subtle, and easy to overlook. It’s considered a standard part of padlock engineering—so manufacturers rarely emphasize it. But locksmiths and security experts know its importance.
How to Use This Knowledge to Extend the Life of Your Locks
Here’s what you can do:
✔ Check the drainage hole regularly
Make sure it’s not clogged with dirt, dust, or mud.
✔ Apply lubricant every 3–6 months
A quick spray into the hole keeps everything smooth.
✔ Don’t cover the hole with tape or paint
It needs to stay open to drain moisture.
✔ Store padlocks upright when possible
It improves drainage and prevents water buildup.
By understanding this tiny feature, you can literally double the lifespan of your locks.
In Conclusion
That small hole on the bottom of your padlock isn’t a flaw—
it’s a smart piece of engineering designed to protect your lock from rust, moisture, and mechanical failure.
Most people never learn this, but now you know the secret behind that mysterious dot.
And the next time someone asks, you’ll be the expert.
