The following table chart defines standard metric external thread size M1.6 to M18 per. ANSI/ASME B1.13M-1995. These thread sizes and classes represent bolts and screws, as well, as other standard external threads. Do not use these values for standard metric internal thread design. All units in mm. These are the M Profile limiting Dimensionings.

Once you know your wire diameter, you need to find out what is the premissable Measurement for your pitch diameter (Depending on the class). Use our Over Wire Calculator to find out!

Armstrong Metalcrafts does prototyping and produces devices that stimulate the imagination, spark a conversation, and enlighten the soul.

For example, M8 is a thread with a nominal diameter of 8 mm (0.315″). If no characters follow the M and diameter, it means that all the other parameters are according to the default as defined in ISO 965-1: Pitch – According to the Coarse pitch series. Number of Starts – One. Class – 6g for external threads and 6H for internal threads.

2013年9月15日 · A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ...

ISO metric threads consist of symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. ISO 261 specifies a detailed list of preferred combinations of outer diameter and pitch for ISO metric screw threads.

The following table chart are standard metric internal thread sizes M 0.25 - M 8 per. ANSI/ASME B1.13M-1995. These thread sizes and classes represent bolts and screws, as well, as other standard internal threads. Do not use these values for …

Metric internal thread dimensions chart according to ASME B1.13M "Metric Screw Threads: M Profile" standard. Minor diameter, pitch diameter and major diameter are given dimensions in the internal thread chart. All dimensions are in millimeters.

Thread pitch diameter, major diameter and minor diameter for M profile external threads are given. All dimensions are in millimeters. Threads produced to ASME B1.13M standard are fully interchangeable with threads that are based on ISO 68-1 basic profile and ISO 965-1 …

Metric bolt sizes are manufactured according to strict metric thread dimensions and specifications defined by the ISO standardisation authority to ensure cross-compatibility between mating components. The metric thread size chart below represents the dimensions of metric coarse machine screw threads as defined by ISO standards.
