A padlock is a common item that serves a significant purpose. People use them for their bikes, outdoor sheds, toolboxes, and gates. They’re designed to withstand the elements and attempts to damage or cut them. However, they have a secret feature, a small hole at the bottom, that also serves an important function.
Serving an Important Function
Using a padlock is one sure way to keep your belongings safe. They’re a small but impactful tool, made of metal, and as a result, padlocks are vulnerable to rust from water damage and extreme weather conditions. Fortunately, they’re designed with a tiny hole at the bottom, allowing water to escape and preventing the padlock from rusting. This small feature helps extend the life and usability of the lock.
Alternative to the Padlock Hole
While the tiny hole in traditional padlocks was once considered revolutionary, there are now weatherproof padlocks available on the market. These designs offer robust protection against the elements, ensuring your belongings stay safe year-round.
Another Reason for the Padlock Design
Besides preventing rust, the small hole at the bottom of a padlock serves another key purpose. If a padlock becomes stuck and won’t open, even with the correct key or code, you can lubricate it through the hole. This helps in freeing up the lock mechanism, making it easier to open.
Other Everyday Things With ‘Hidden Features’
Padlocks aren’t the only items that come with secret or hidden features. There are other handy objects in everyday life designed to serve multiple purposes.
Screwdrivers as Wrenches
Knowing a bit about car maintenance is always useful, especially given the number of vehicles on the road. Many mechanics face the common challenge of working in small spaces. Fortunately, most screwdrivers can be slid into a wrench, making it easier to reach those tight spots.
Color Swatch on Clothes
Clothing used to come with a color swatch more frequently, although some high-quality brands still include them. These swatches have several uses. They help in color-matching fabrics or threads if the clothing becomes ripped or damaged. They also allow you to test how certain products, like laundry soap, will affect the garment’s color. Essentially, these little swatches act as a tester piece, so you know exactly how to care for your new clothing.
Gas Indicator
Forgetting which side of your car the gas tank is on is a common issue. Thankfully, most car manufacturers have included a small triangular indicator near the gas gauge to remind you of the correct side.
A Logo Has 2 Roles
The Heinz 57 label is often seen on various sauces like ketchup and steak sauce. This logo not only serves as a branding element but also indicates where to tap the bottle, ensuring the sauce flows smoothly.
Padlocks and other items mentioned above demonstrate the thoughtfulness behind everyday designs, making our lives a little easier and more convenient.
