Revealing the Puzzle of the Minuscule Hole Found at the Bottom of Locks

Locks are something you find in most homes, but have you ever noticed a small hole underneath them? Maybe you haven't because it's really tiny, but it's actually quite important.

The reason for this tiny hole is to make the lock stronger. Many locks are on outside doors and have to deal with bad weather like rain. So, this hole helps water drain out. If the hole wasn't there, the inside parts could get rusty and damaged quickly.

That's why locks have this little hole – to let water out and keep the inside safe. It makes sure the lock works well for a long time.

And guess what? This small hole can also help if your keys get stuck. If you put some oil in this tiny hole, your keys can move more smoothly.

So, this little hole helps the lock handle all kinds of weather and makes it tougher.
