When it comes to fasteners, the M20 bolt is a commonly used type known for its versatility and strength. In order to appropriately fasten an M20 bolt, it is essential to have the correct socket size. The socket size for an M20 bolt is 30mm. The M20 bolt is a metric bolt, which means it is measured in millimeters. The size of the bolt refers to the diameter of the shank of the bolt. The M20 bolt has a diameter of 20mm, which is equivalent to about 0.78 inches. This medium-sized bolt is often used in machinery, automotive applications, and construction projects. In order to properly tighten or loosen an M20 bolt, it is important to use a socket that matches the size of the bolt head. Using the correct socket size will prevent damage to the bolt head and ensure a secure connection. The socket size for an M20 bolt is 30mm, which is slightly larger than the diameter of the bolt head to allow for easy fitting

m20 bolt socket size. When selecting a socket for an M20 bolt, it is important to choose a high-quality, durable socket that can withstand the torque needed to fasten the bolt securely. A socket made from chrome vanadium steel is a good choice for this purpose, as it is strong and resistant to wear and tear. In addition to the socket size, it is also important to consider the type of drive of the socket. The most common drive types are square drive and hexagonal (or hex) drive. For an M20 bolt, a socket with a square drive is typically used, as it provides a secure fit and is less likely to slip during use. When using a socket to fasten an M20 bolt, it is important to ensure that the socket is properly seated on the bolt head before applying torque. Using a socket that is not fully engaged can result in stripped bolt heads or injury. It is also important to use the correct amount of torque when tightening the bolt to prevent over-tightening or under-tightening. In conclusion, the M20 bolt is a versatile and commonly used fastener that requires a 30mm socket for proper installation and removal. By using the correct socket size and drive type, as well as following proper tightening procedures, you can ensure a secure and reliable connection when using an M20 bolt.
