If you’re mounting your Samsung TV using VESA bolt holes, you may be wondering what size screws you need. Fortunately, the m8 screw size is well-defined.

The m8 designation refers to a metric (M) sized bolt or screw that is 8 millimeters in diameter, about the same as a 5/16 bolt or screw. The M size designation is followed by a number that indicates the thread pitch.
Length

The length of a screw is an important consideration, especially when you’re working with tight spaces. The longer a screw is, the more force you need to apply to turn it.

Screw sizes are usually indicated by a letter, followed by a number. For example, M8 is a metric screw size, meaning that the bolt has an outer diameter of 8 millimeters and a thread pitch of 1.0 mm.

Screws are used for various purposes in machinery, furniture, and other equipment. They are also a great alternative to nails because they’re stronger, offer a more secure hold, and don’t rust as easily. However, when choosing a screw size, it’s important to know the specifications and requirements of each application. There are several factors to consider when determining the proper size, including length, head type, and material. Using the right screws ensures that your equipment is assembled correctly and safely. Whether you’re working with wood, machine screws, or sheet metal, there are a wide variety of options available to meet your needs.
Diameter

The diameter of a screw is the size of its nominal shaft diameter, which is measured in millimeters. This measurement differs from standard fastener measurements, which are indicated by the number of threads that cover a one-inch distance.

Metric bolt sizes are identified by the letter M followed by a number. In addition to the diameter, a metric screw designation also specifies its thread pitch and length.

M8 screws have a nominal shaft diameter of 8 mm and a thread pitch of 1.25 mm. They are commonly used in bike frames and components, such as brake mounting bolts, derailleur mounts, stem bolts, seat post bolts, and more.

It’s important to use the right tools for tightening and unscrewing m8 screws. If you use a wrench that is too big, it can damage the bolt. Typically, an M8 screw will require a 13 mm spanner or Allen key. You may also want to consider using a nyloc or dome nut, which are taller than standard nuts and help prevent them from sliding out of the head.
Thread Pitch

In the metric system, bolts and nuts are sized by their major diameter, the distance across the top of two adjacent thread peaks, and their pitch, which is the number of thread peaks per inch. For example, an M8 screw has a major diameter of 8 millimeters and a thread pitch of 1.25 millimeters.

When using a wrench or Allen key, the correct size must be used to prevent damaging the screw. Clearance holes are typically drilled somewhat larger than the bolt shaft diameter to allow for misalignment.

Determining the requisite tapping hole size is easy by subtracting the metric bolt diameter from the thread pitch. For example, a standard coarse thread M8 bolt with a 1.25 mm pitch requires a hole of 6.75 mm to be tapped. A fine thread M8 bolt has a thread pitch of 1 mm, so the required tap hole size is 7.25 mm.
Proof Load

The “M” designation in a screw size indicates that the screw has a metric thread. This means that it will fit easily into a hole that has been drilled to the appropriate size for the screw. The screw’s outer diameter, also known as its major diameter, is indicated by the number following the “M.”

The proof load of a bolt is the maximum amount of force that it can bear without plastic deformation. The yield strength is the point at which a fastener starts to lose its ductility, and it’s the force that will cause the bolt to break under tension.

All of these measurements are important to know if you’re going to use a bolt. It’s essential to choose the right bolt for the job so that it will hold together properly and not break or fall apart under stress. Fortunately, understanding metric callouts is much easier than understanding imperial ones. So don’t hesitate to use this information when purchasing your next bolt!m8 screw dimensions
