M6 Bolt

What is an m6 bolt?

M6 bolt is a metric bolt, where "M" represents the tooth shape symbol for regular threads, and "6" represents a diameter of 6 millimeters for threads. Metric bolts are a common type of bolt, and their size parameters are marked in millimeters.

The m6 bolt size parameters refer to the diameter and length of the bolt. The diameter M6 bolt is 6 millimeters. As for the length, the length of the bolt can be determined based on specific assembly requirements, and there is no fixed standard length. For example, a 50mm m6 bolt means the bolt is the length at 50 mm, and the diameter at 6 mm.

What determines the size of a bolt?

The size parameters of bolts depend on multiple factors, including thread form, diameter, length, material, etc. The size of bolts is determined by international standards organizations (such as ISO) or national standards and selected based on specific application requirements. The size parameters of bolts include thread form: Bolts can have different thread forms, such as metric threads (M) and inch threads (UNC, UNF, etc.). The thread form determines the parameters, such as the pitch and tooth shape of the bolt. Diameter: The diameter of a bolt refers to the size of the outer diameter of the thread, usually expressed in millimeters (mm) or inches (inches). Length: The length of a bolt refers to the length of the threaded portion, usually expressed in millimeters (mm) or inches (inch). Material: The material of bolts can be carbon steel, stainless steel, alloy steel, etc. Different materials of bolts have different strengths and corrosion resistance. The size parameters of bolts are usually marked on the bolt head or thread for user selection and identification. When selecting bolt sizes, it is necessary to determine appropriate size parameters based on specific application and design requirements.

How to determine whether a bolt is a metric bolt or a standard bolt?

The thread form of metric bolts usually starts with "M," such as M6, M8, etc., indicating that the thread diameter is millimeters. The thread form of standard bolts is usually measured in inches, such as 1/4, 3/8, etc. Metric bolts usually have diameter and length dimensions marked on their heads, such as M6x20 for metric bolts with a diameter of 6mm and a length of 20mm.

Use tools such as thread gauges or calipers to measure the diameter and pitch of threads and then compare them with the parameters of metric and standard threads. The pitch of metric threads is usually in millimeters, while the pitch of standard threads is usually in inches.
