The Importance of Knowing the M8 Screw Size
Screws are a crucial part of the hardware that keeps machinery and equipment assembled. They also offer a secure connection and are less prone to rust than nails. However, there are many different types of screws and each one has a specific use. Some are designed for fastening metals, while others can be used in plastic or wood. In addition, some are made with coarse or fine threads. These differences affect the performance of the screws and are important to understand before buying them.
Metric screw sizes are usually specified by their diameter and thread pitch, which is measured in millimeters. For example, an M8 screw has a shaft diameter of eight millimeters and a thread pitch of 1.0 millimeters. This is a coarse-thread screw, which means that it has wider threads than a fine-threaded screw of the same size. Coarse-threaded screws have a lower susceptibility to seizing, cross-threading, and galling.
Most metric screws are stamped with the letter “M” in their name and the corresponding number. They may also have a specification written on the packaging. This identifies the screw as either coarse or fine-threaded and gives the user an idea of how to use it. For example, M10 is a coarse-threaded screw while M12 has a fine-threaded thread.
In some cases, the m8 screw size is also indicated by its shank and thread diameter. This can help the user determine whether a hole is too small to fit the screw or if it is the correct size for the intended application. The m8 screw is commonly used in bicycles as well as other mechanical devices. In some cases, the screw can be used to secure the handlebars or the derailleur to the frame of the bike.
Generally, the screw is installed with an Allen wrench or spanner that has a size compatible with its diameter. For example, a spanner or Allen key with a size of 13 mm can be used to tighten the m8 screw. Using the wrong-sized tool can damage the screw and cause it to slip or break.
It is important to know the m8 screw size before purchasing it. This can be done by calculating the tap drill size of the bolt. This is necessary because the m8 screw has a coarse thread and will require a larger tap drill size than a fine-threaded screw with the same diameter. For instance, a fine-threaded M6 bolt requires a drill bit of size 6 mm, while an M8 bolt will need a drill bit of size 8.25 mm.
