A padlock is a common object with a very important use. They are used by people for gates, toolboxes, bicycle storage, and outdoor sheds.

They are made to resist cuts and other attempts to harm them from the environment. They do, however, contain a hidden feature—a little hole on the bottom—that has a very important function.

Serving an Important Function

Padlocks are small but powerful metal tools used to prevent theft. However, they are vulnerable to rust and damage caused by weather extremes and water. Fortunately, padlocks have a secret hole on the bottom that allows water to escape, preventing rust and extending their lifespan.

Alternative to the Padlock Hole

While the hole on padlocks is a revolutionary feature, there are now waterproof padlocks available in the market. These waterproof padlocks ensure that your belongings remain safe and secure throughout the year.

Another Reason for the Padlock Design

The little hole on the bottom of a padlock serves another purpose besides preventing rust. In some cases, even with the correct code or key, a padlock may become stuck or difficult to open. In such instances, a synthetic lubricant can be applied through the hole to facilitate opening the padlock.

Other Usual Items With “Hidden Features”

Not only padlocks, but there are also other everyday items with hidden features. Let’s take a look at a few:

Screwdrivers as Wrenches

Working on cars can be challenging due to the tight spaces and crevices. To make things easier, most screwdrivers can be made smaller by sliding them inside a wrench, allowing you to reach those difficult areas.

Color Swatch on Clothes

Some clothing items used to come with a color swatch. These swatches serve multiple purposes. Firstly, they can be used to match materials or threads when garments are torn or damaged. Additionally, they can be used to test how laundry soap or other substances will affect the color of the item, helping you take care of your clothes better.

Brass doorknobs and padlocks

Brass is a popular metal used for doorknobs, padlocks, and other frequently touched items because of its antimicrobial properties. It helps reduce the spread of germs and keeps these items cleaner.

Gas Indicator

It’s common to forget which side of the car the gas tank is located on. To solve this problem, automakers have included a gas indicator near the gas gauge. The indicator, usually shaped like a triangle, points to the side of the car where the tank is located.

A Logo Has 2 Roles

The Heinz 57 label found on sauces like ketchup and steak sauce serves more than just branding. It also acts as a reference point to tap the bottle and ensure the sauce flows freely.

Padlocks and the other mentioned items are just a few examples of the incredible inventions and designs that aim to simplify our lives.
