The Real Reason Padlocks Have a Tiny Hole
Many people never question the small hole at the bottom of a padlock, but this little feature plays a big role in keeping the lock functional.
1. It Prevents Rust and Corrosion
When padlocks are exposed to rain or humidity, water can get inside.
The tiny hole acts as a drainage point, allowing water to escape rather than collect, helping prevent rust and internal damage.
2. It Helps Lubricate the Lock
If a padlock becomes stiff or hard to open, you can spray lubricant directly into the hole.
This delivers the oil straight to the internal mechanism, restoring smooth movement.
3. It’s Not Needed on Waterproof Locks
Modern waterproof padlocks often skip this feature.
Their bodies are sealed using new technology that blocks water from entering entirely.
Other Everyday Items With Hidden Features
1. Screwdriver + Wrench Combo
Some screwdrivers are designed to fit through the hole of a small wrench, giving extra torque.
Perfect for reaching difficult screws or applying more force safely.
2. Clothing Fabric Swatches
That little piece of extra fabric attached to new clothes isn’t for decoration.
It lets you test detergents, stain removers, or ironing techniques without risking the garment.
3. Brass Handles and Doorknobs
Brass is naturally antimicrobial.
That’s why it’s widely used for door handles—because it helps reduce the spread of germs.
4. The Arrow on Your Car’s Fuel Gauge
If you always forget which side your fuel tank is on, look at the fuel gauge.
A small arrow next to the gas pump icon points toward your tank’s location.
5. The Heinz 57 Trick
The famous 57 on a Heinz ketchup bottle marks the best spot to tap if you want the ketchup to flow smoothly—no shaking or squeezing required.

2. Can I use any oil to lubricate a padlock?
Use a light machine oil or a lock-specific lubricant. Avoid cooking oils—they attract dust.
3. Why do brass items stop germs?
Brass naturally kills bacteria over time through a process called oligodynamic effect.
4. Are these hidden features common across all brands?
Many are universal, but some depend on the manufacturer or product design.
