Purpose of the Hole
This tiny hole allows water to escape, preventing rust and prolonging the padlock’s life. Without this feature, padlocks would be more susceptible to damage from water and extreme weather conditions.
Weatherproof Alternatives
While the tiny hole was once revolutionary, there are now weatherproof padlocks available. These are designed to keep belongings safe in any weather, offering an alternative to the traditional padlock design.
Additional Benefit
Besides preventing rust, the hole serves another purpose. If the padlock gets stuck, synthetic lubricant can be applied through the hole to help it open.
