The first thing to know about screws is that there are a lot of different types and sizes. A #8 screw, for example, is a type of screw that is typically used in woodworking. It is also a size 8 screw, which means that it is slightly smaller than other screws.

The reason for this is because the #8 screw was designed to be used in thinner materials.

When it comes to screws, size does matter. A #8 screw is a medium-sized screw that can be used for a variety of purposes. It’s not too big or too small, making it perfect for projects that require a little extra stability.

This size screw is also great for attaching hardware, like hinges and handles, to cabinets and furniture. If you’re not sure what size screw you need, a #8 is always a good option to have on hand.

8 Screw Diameter in Mm

The nominal screw diameter (in millimeters) is the outside diameter of the screw as described in a Screw thread standard, such as ISO 6898. The internal thread tolerance class 6g applies unless specified otherwise. For example, an M8 x 1.25 screw has an 8 mm nominal outer diameter and 1.25 mm between threads.

The “M” designation for metric screws indicates the coarse pitch specified in ISO 261[1] which includes both external and internal threads.[citation needed] In general, larger screws have a coarser pitch than smaller screws; however this is not always true (e.g., 3/4″-10 UNC is coarser than M6x1).
