Padlock design: The purpose of the small hole at the bottom
High-quality padlocks often feature a small hole at the bottom. This opening serves several practical functions for users, particularly those using locks outdoors.
One primary purpose is to allow rainwater to drain out, which prevents moisture from entering the mechanism and rusting the internal spring. Additionally, the hole helps prevent the locking mechanism from freezing during winter frost temperatures.
The opening also facilitates maintenance by making it easier to apply oil to the lock if the key becomes difficult to turn or the shackle becomes hard to operate.
