Padlocks are part of our daily lives: whether it is a matter of securing a bicycle, a locker or a door, and they protect our property. Yet a small detail often intrigues: Why is there a hole under the base of the padlock? At first glance, it seems insignificant, but it actually plays a key role in the longevity and proper functioning of the mechanism.
Protection against rust and moisture
One of the main reasons for the existence of this hole is to prevent the accumulation of water inside the chains. When a chain is exposed to the weather (rain, snow, moisture), the water could infiltrate and cause rust. This oxidation could then block the internal mechanism and make the opening difficult, if not impossible.
Thanks to this small hole, the water can flow freely, avoid the formation of rust and thus extend the life of the padlock. A simple but effective design detail.
