Become a hardware store savant

How old were you when you learned these hardware staples' names'?

It happens to the best of us: you embark on a mundane home repair, only to realize that there is a broken thing in need of replacement. But, alas, you don’t know the name of said item. Spare yourself the embarrassment of having to show the hardware store clerk a clumsy smartphone picture of the wretched piece itself. After reading this article, you will be able to walk into the store and order a wing nut or an escutcheon with the confidence of a seasoned contractor.

A toggle bolt is a fastener designed for hollow walls such as drywall. Its secret weapon is a pair of spring-loaded wings that fold to fit through a hole and then expand behind the wall, spreading the load over a larger area.

The word toggle comes from an older mechanical term for a pivoting or folding device. The name describes exactly what the wings do: they change position after passing through the wall. As drywall construction became widespread during the twentieth century, toggle bolts became a common household fastener.

A wing nut is probably one of the easiest hardware names to understand. Instead of a standard hexagonal shape, it has two projections that resemble wings, allowing it to be tightened or loosened by hand. You might find it located under the toilet tank.

The design became popular wherever quick adjustments were needed without tools. You’ll find wing nuts on equipment, musical stands, machinery, and countless household items. Their name is purely visual, based on the shape that makes them so convenient.

Among hardware terms, escutcheon sounds especially mysterious, right? It refers to the decorative or protective plate surrounding a keyhole, pipe opening, or door fixture.

The word originally referred to a shield used in heraldry. Over time, the term was applied to hardware because the plate "shielded" or covered an opening. Although most people encounter escutcheons regularly, almost nobody realizes that they are using a word with medieval roots.

The carriage bolt earned its name from the horse-drawn carriage era. Builders needed a fastener that could secure wooden components without leaving a protruding head that might snag clothing, cargo, or harnesses. You might find one on an outdoor deck.

Its smooth, rounded head and square neck solved the problem. The square section bites into wood and prevents the bolt from turning while the nut is tightened. Even though carriages largely disappeared long ago, the name remains in use today.

A lag screw is a heavy-duty fastener commonly used in timber construction. It looks like a giant screw but is often tightened with a wrench because of its large hexagonal head. It can usually be found on TV wall mounts.

The origin of the word lag is uncertain, but it likely derives from an older term associated with large wooden structural members. The name reflects the fastener’s traditional role in securing heavy timbers for buildings, bridges, docks, and other major structures.

Sometimes hardware names are exactly what they seem. An S-hook is simply a hook shaped like, you guessed it, the letter S. You might recognize it from kitchen pot racks.

Its design has existed for centuries because of its simplicity and usefulness. One end can attach to a support while the other holds an object. From hanging pots and tools to organizing workshops and warehouses, the S-hook remains one of the most versatile pieces of hardware ever created.

Aside from being a common name, many people assume that "molly" describes a type of fastener. It began as a trademark. In 1934, inventor George Frederick Croessant patented an improved hollow-wall anchor sold under the name MOLLY. Today, it can be seen in curtain rod brackets.

The product became so successful that the brand name gradually turned into a generic term. Today, countless people use "molly bolt" to describe expandable wall anchors, even when they are not made by the original manufacturer.

The purpose of a lock washer is built directly into its name. It is designed to help prevent a fastener from loosening because of vibration or movement. It can often be found in washing machines and dryers.

As automobiles, railroads, and industrial machinery became more common during the nineteenth and twentieth centuries, engineers needed better ways to keep bolts secure. Lock washers became one of the simplest solutions, helping assemblies stay tight under demanding conditions.

A nyloc nut contains a nylon insert that grips the bolt’s threads. This extra friction helps keep the nut from backing off when subjected to vibration. It can be found in skateboards and roller skates.

The name combines two words: nylon and lock. Like many successful engineering products, the term eventually became familiar beyond the company that originally promoted it. Today, nyloc nuts are widely used in automotive, aerospace, and industrial applications.

This acorn nut is not the kind that grows on oaks. An acorn nut bolt features a rounded, closed end that covers the exposed tip of a bolt. Viewed from the side, the shape somewhat resembles the acorn that grows on trees.

The design serves both practical and aesthetic purposes. It protects people from sharp threads while helping shield the bold from dirt and moisture. That’s why acorn nuts are often found on furniture, bicycles, playground equipment, and ornamental metalwork.

A draw bolt works by pulling two parts tightly together. Unlike a standard bolt-and-nut combination, it often functions as a latch that creates tension when closed.

The name comes directly from the verb draw, meaning to pull. Draw bolts are commonly used on toolboxes, storage cases, industrial cabinets, and equipment enclosures where a secure, tight closure is needed.

A T-nut, also known as a tee nut, gets its name from its shape. Viewed from the side, its threaded barrel and flange resemble the letter T.

The design allows a bolt to be inserted from one side of a wooden panel, while the T-nut anchors itself from the other. T-nuts are especially common in furniture, speaker cabinets, climbing walls, and other products that require strong threaded connections in wood.

We just know that we know nothing

12 facts that people often get wrong

No one can claim to know everything, but most people go through life confident about certain things. However, some of these widely held beliefs are not actually correct, despite their popularity. Let’s have a look at some "facts" you might have gotten wrong!

The idea that insects—particularly mosquitoes—are not animals is widespread, but it’s also incorrect. In fact, insects are the most diverse group within the Animal kingdom, with more than a million species described and representing more than half of the animal population of the planet.

The mistake comes from not considering that "fruit" is not only a culinary term but also a botanical one. Botanically, a fruit is the part of a plant that develops from a flower and contains seeds. This makes tomatoes, peppers, cucumbers, eggplants, and many other foods that we call vegetables actually fruits in the scientific sense.

Countries have a political delimitation, while continents are divided according to geographical criteria. The Russian Federation is the largest country on Earth, bordering fourteen other countries and extending across eleven time zones. It spans across a good part of Eastern Europe, but also across the Ural mountains—one of the recognized borders between Europe and Asia—and stretches deep into northern Asia.

While cold weather isn’t harmless, it is not the direct cause of illnesses like the flu, which are caused by viruses. In colder months, people tend to spend more time indoors and often avoid ventilating rooms, creating conditions that make it easier for viruses to spread and cause illness.

Bats might not prefer to be out during bright daylight, but this does not mean that they are blind. In fact, many species have excellent eyesight, though it is adapted to low-light or nighttime conditions. On top of that, bats also use echolocation, which allows them to navigate and hunt with remarkable precision in complete darkness.

The belief that you must wait a full day before reporting someone missing is a myth popularized by movies and TV shows. In reality, the law does not require a waiting period. In fact, law enforcement agencies stress that the first 24 hours are often the most critical, so a missing person should be reported immediately.

Some man-made structures are visible from space without magnification, but despite popular belief, the Great Wall of China is not one of them. While it is quite long, being over 13,000 miles long, it is relatively narrow, and its earthy colors blend in with the surrounding landscape, making it nearly impossible to spot with the naked eye from orbit.

This one is tricky: Mount Everest is the highest mountain on Earth (29,032 feet)… if you measure the distance from sea level to peak. For the actual tallest mountain, the answer might vary depending on how you measure. Measured from base to summit, Mauna Kea in Hawaii is the tallest at 33,474 feet—though much of it is underwater. Mount McKinley (Denali) in Alaska rises about 18,000 feet from its base to the peak, making it the tallest mountain entirely above sea level. And Ecuador’s Mount Chimborazo, while shorter in height, is the farthest point on Earth from the planet’s center due to the equatorial bulge.

The Earth is tilted on an axis, which causes the amount of sunlight each hemisphere receives to change as it orbits the Sun. Because of this tilt, when the Northern Hemisphere is tilted toward the Sun and experiences summer, the Southern Hemisphere is tilted away and experiences winter—and vice versa. This is why the Southern Hemisphere celebrates Christmas during summer.

Standard medical advice is to gently guide a sleepwalker back to bed rather than waking them, but not because waking them is inherently dangerous. People tend to sleepwalk during deep sleep, so waking them up might startle them or cause confusion and disorientation.

Hair color and thickness are determined by genetics, not by shaving. Hair naturally gets thin at the ends, so when you shave it, the hair shaft appears to be thicker and darker because of the blunt cut. But it's just an optical illusion; the natural size of the shaft remains unchanged.

Coffee is a natural diuretic, meaning it can increase trips to the bathroom. However, the water in brewed coffee still contributes to your hydration and offsets its mild diuretic effect. If you consume coffee in moderation—3 to 5 cups a day, depending on your tolerance—you should be alright. However, drinking extra water on the side is never a bad idea.
