These features are meant to keep moisture out from the start, so the lock doesn’t need a drainage hole at the bottom. But for millions of traditional padlocks still in use on gates, sheds, storage units, and lockers, that tiny opening remains an essential part of the design.
Small detail, big impact
It’s easy to miss, but the little hole at the bottom of a padlock is one of the reasons it keeps working year after year. It lets water escape, gives you a way to lubricate the inner mechanism, and even helps professionals inspect and test the lock when needed.
Without it, many padlocks would rust from the inside out and fail much sooner than we expect.
So the next time you close a padlock on something important, take a second to flip it over and find that tiny hole. It’s a simple reminder that even the smallest design choices can make a big difference in how well something protects what matters to you.
