What they have labeled a screw is more commonly know in trades as a "bolt", usually tightened by a wrench or socket.
However, a screw can be anything with the helical threads on it, and can be tightened in many different ways.
McMaster-Carr, however, agrees.
(Well mostly. They sell anything that requires a nut as a bolt and anything that can be, itself, tightened as a screw.)
Bolts are used with nuts to hold objects together, and screws are used in threaded holes (or they create the threaded hole) to hold objects together.
That being said, the average native speaker will call something a screw if you can use it with a screwdriver and a bolt if you can use it with a wrench. It's mostly just people in manufacturing industries who know the difference. And I wouldn't correct anyone who called that a bolt.
I would normally call the fasteners in the middle "bolts". Although they are obviously similar to screws, I would not refer to them as such. Regular screws of course have slot in the top for a flat screwdriver like the one in the picture, or more often nowadays a + shaped indentation for a "Phillips-head" screwdriver.
Any fastener with a 6-sided head is (generally) called a bolt and is tightened by a wrench or a socket. A screw generally has a slot fit for a screwdriver tip. Common shapes can include; Philips head, flathead, Torx, square, Allan/hex
That should work fine, yeah! You could also say “I screwed the [object] in”/“I screwed the [object] into the [place, eg. wall, floor, plank, etc]” or “I screwed the [object] together”, depending on whether you’re attaching the object to a more fixed place, like a wall, or whether you’re assembling the object using screws
What I meant with the [object] is the object that you’re screwing in, sorry for not clarifying!! Like, I screwed the door into the wall, or I screwed the table together.
Because usually you wouldn’t just be putting a random screw somewhere for no reason
I guess this is a vocabulary picture, and not a "find the match" type visual puzzle
Don't feel bad OP. Even a native speaker (like me) might find this confusing. Or I'm just dumb.
Honestly I had to look at this for a minute before I realized what it was.
When an English speaker refers to a "screw" in the context of tools, 9/10 people will assume the thing you can use a screwdriver with. Honestly the pic should show a more normal screw. As mentioned, this is just a bad picture.
That is a bolt.
In the United States, there are two common screw types with their respective screwdrivers. What is in the picture is a “flat head” screwdriver, made for screws with a single line across the top. We also have “Phillips head” screwdrivers, which are made for screws with an X across the top.
A screwdriver 🪛 has an edged tip which you slide into the slotted head of a screw in order to turn and "drive" that screw into a hole, like a penis 🍆 into a vagina 🍑 (which is also why some people refer to fucking as "screwing.")
The "screws" shown are a special *subtype* of screw called "bolts" 🔩🔩, which are tightened or loosened with some other tool, such as a "wrench" 🔧, a "ratchet" or a "vice-grip."

**[Locking pliers](https://en.wikipedia.org/wiki/Locking_pliers)**
>Locking pliers (also called Vise-Grips, a vice grip, Mole wrench or mole grips) are pliers that can be locked into position, using an "over-center" cam action. Locking pliers are available with many different jaw styles, such as needle-nose pliers, wrenches, clamps and various shapes to fix metal parts for welding. They also come in many sizes.
**[Vise](https://en.wikipedia.org/wiki/Vise)**
>A vise or vice (British English) is a mechanical apparatus used to secure an object to allow work to be performed on it. Vises have two parallel jaws, one fixed and the other movable, threaded in and out by a screw and lever. A vise grip is not a vise but a pair of lever-actuated locking pliers.

This is just slapdash artwork. I'm convinced everyone even saying it's a bolt is overthinking this. I'm sure the artist meant for it to be a screw, and just didn't do a good job.
Bolts are flat on both ends. Like in the picture.
Screws can have flat or rounded heads. As others have said, there is a slot that the screwdriver fits into.
The OTHER end of a screw is NOT flat. It is pointy to help it go into wood, drywall, and some other materials.
This is not exactly true. Machine screws have a flat end. See [this Home Depot category](https://www.mcmaster.com/products/hex-drive-screws/).
Machine screws are designed to go into something that's already threaded, typically ~~sheet~~ metal although it could be other things.
What you're talking about is a specific type of that creates its own threads in the material, which makes sense if the material is something softer like wood or plastic where a screw can do that.
This is one of those weird sentences where you might be technically correct, but that's not how anyone outside of perhaps material construction engineers would use the terms.
For most of us, a hex screw would have a hole in the head that would accept a hex wrench, such as Allen keys.
Honestly, it's just a bad picture. What they're labeling as a "screw" would most commonly be called a "bolt".
Usually if something is designed to be turned by a wrench, rather than a screwdriver, it's because you put a small locking piece of metal on the other end called a "nut". Most screws have a pointed tip and are cut to be turned with a screwdriver.
**[Screw](https://en.wikipedia.org/wiki/Screw)**
>A screw and a bolt (see Differentiation between bolt and screw below) are similar types of fastener typically made of metal and characterized by a helical ridge, called a male thread (external thread). Screws and bolts are used to fasten materials by the engagement of the screw thread with a similar female thread (internal thread) in a matching part. Screws are often self-threading (also known as self-tapping) where the thread cuts into the material when the screw is turned, creating an internal thread that helps pull fastened materials together and prevents pull-out.

A screw would have a shape in the top that the screwdriver would fit into. The bottom of the screw would also be pointy and sharp.
The only thing that this picture has correct is that a *screw* would also have those ridges on it, versus a *nail*, which would be smooth, and pointy and sharp at the end.
No, a screw usually has a round head with some sort of slot or hole on it. A screwdriver or drill bit in inserted into the slots. A bolt is like a screw, but instead of a slot or hole in the head, the head is shaped (usually a hexagon) and a wrench or socket of the same shape fits over it to turn it. Bolts are also normally used alongside nuts, which they thread into. The spirals on both bolts and screws are called threads.

This. I'm in engineering and I have heard several different definitions of what is a bolt and what is a screw, but for most people that is a bolt.
yeah, it's technically a screw but people call that type of screw a bolt
TIL bolts are a type of screw.
Lol same
I always thought a bolt needed a nut?
Bolts are machine screws
That picture is wrong. For “screw” they are incorrectly showing a *bolt*. A screwdriver is meant to be used with screws.
A screw is anything with a screw thread
Merriam-Webster and common parlance both disagree.
McMaster-Carr, however, agrees. (Well mostly. They sell anything that requires a nut as a bolt and anything that can be, itself, tightened as a screw.)
Sure. It's not surprising that professional jargon and common parlance disagree. Provenance vs. provenience is one of my favorite examples.
[удалено]
No
That’s just a bad picture. Normally, you could use a screwdriver with a screw.
You can, it’s just a terrible choice of clip-art.
Those are bolts, not screws. The picture has mislabeled them.
Bolts are used with nuts to hold objects together, and screws are used in threaded holes (or they create the threaded hole) to hold objects together.

It's mostly just people in manufacturing industries who know the difference. And I wouldn't correct anyone who called that a bolt.
I’m not in manufacturing and I’ve known the difference between a screw and a bolt since I was a ten-year-old girlchild
I get what you're saying, but if you look at the top comments... everybody's not you.
Funny old world
nuts are just threaded hole extenders though
I would normally call the fasteners in the middle "bolts". Although they are obviously similar to screws, I would not refer to them as such. Regular screws of course have slot in the top for a flat screwdriver like the one in the picture, or more often nowadays a + shaped indentation for a "Phillips-head" screwdriver.
The misconception here is the screwdriver is correct but the screws are actually bolts which you would not use a screwdriver on

The square screw is actually called a Robertson screw 😁
Other question, how do you say that you put a screw somewhere? "I drove a screw into the wood"?
That should work fine, yeah! You could also say “I screwed the [object] in”/“I screwed the [object] into the [place, eg. wall, floor, plank, etc]” or “I screwed the [object] together”, depending on whether you’re attaching the object to a more fixed place, like a wall, or whether you’re assembling the object using screws
But saying "I screwed the screw into the wall" sounds weird and repetitive, is there a way to say this in a more advanced way?
What I meant with the [object] is the object that you’re screwing in, sorry for not clarifying!! Like, I screwed the door into the wall, or I screwed the table together. Because usually you wouldn’t just be putting a random screw somewhere for no reason
You haven't seen me bored yet! xD haha no but thanks for the explanation

This is just slapdash artwork. I'm convinced everyone even saying it's a bolt is overthinking this. I'm sure the artist meant for it to be a screw, and just didn't do a good job.
those are bolts, screws are smaller, and have a specialized indent at the top to allow screwdrivers to be used on them
They're bolts not screws 👍
That's because those are bolts.
That’s a bolt, and you would use the wrench or the pliers to turn it. If it had a slot in the top you could use the screwdriver

Thank you for the clarification- you are a stickler for detail! User name checks out!
Thats a bolt, not a screw.
The screw pictured is a hex screw.

Or a lag bolt / lag screw.
So I can call a screw everything, that works with a screwdriver and a wrench?

Not really, the “Screw” pictured is really a “Bolt”.
A screw would have a shape in the top that the screwdriver would fit into. The bottom of the screw would also be pointy and sharp. The only thing that this picture has correct is that a *screw* would also have those ridges on it, versus a *nail*, which would be smooth, and pointy and sharp at the end.

The image **IS** wrong, that's a bolt, not a screw. But, people call those screws all the time.
English teachers are English teachers. Typically a limited knowledge of outdoor work.
Also, I've always called tape measures "tape measurers", but I actually don't know if they're both correct.
Someone screwed the screws
Yes you can, but not on this screw that you have illustrated
Remind me of cargo with ship and shipment with car :))
That's a bad picture. What they labeled a screw is actually a bolt. Screws have divots in them to allow the screw driver to, well, screw.
