Some People Still Don’t Realize What This Tiny Hole on a Padlock Is For Some People Still Don’t Realize What This Tiny Hole on a Padlock Is For
Have you ever paused to really look at the small details built into everyday objects? Those tiny features we often ignore often serve surprisingly clever purposes. Here are a few examples worth noticing.
The Padlock’s Hidden Feature
That small hole at the bottom of a padlock isn’t just part of the design—it plays a key role. Although padlocks protect our belongings, they’re still vulnerable to the elements. Moisture can build up and cause rust, but that little opening allows water to drain out, helping the lock stay in good condition
It’s useful in another way, too. If a padlock becomes stiff or difficult to turn, you can apply lubricant through the hole to get it moving smoothly again—like giving the lock a quick tune-up.
Some modern waterproof locks eliminate the need for the hole altogether by using upgraded designs that keep water out entirely.
