A padlock is a common tool used to secure various items such as bikes, outdoor sheds, toolboxes, and gates. These locks are built to withstand different weather conditions and attempts at tampering. Despite their sturdy construction, padlocks have a hidden feature – a small hole at the bottom that serves a crucial function.
This feature plays a vital role in ensuring the longevity of the padlock. Made of metal, padlocks are prone to rusting when exposed to water and severe weather. The tiny hole at the bottom allows any trapped water to escape, preventing rust formation and ultimately extending the lifespan of the padlock.
