What size are grub screws ?

Grub screws can come in all sorts of different sizes, depending on what they're being used for. They can be really tiny, like the ones used in RC cars, or they can be larger, like the ones used in industrial machinery.

When it comes to RC cars, for example, the grub screws used in electric motors are usually very small - we're talking just a few millimeters in length! But even though they're tiny, they're still really important for keeping the motor's gears in place.

So, if you're looking for grub screws for your own projects, you'll want to make sure you're getting the right size for the job. You can usually find grub screws at hardware stores or online, and they'll usually be labeled with their size in millimeters or inches.

It's important to note, though, that not all grub screws are created equal. Some are made from higher-quality materials or are designed for specific uses, so you'll want to make sure you're getting the right type of grub screw for your particular application.
