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.

M12 : Basic Thread Dimensions (Pitch, minor & major diameters, depth, lead), Tolerance range for all applicable classes and much more

The metric M profile threads of tolerance class 6H/6g are intended for metric applications where the inch class 2A/2B have been used. At the minimum material limits, the 6H/6g results in a looser fit than the 2A/2B.

The following table chart are standard metric internal thread sizes M 9 - M 24 per. ANSI/ASME B1.13M-1995. These thread sizes and classes represent bolts and screws, as well, as other standard internal threads.

Charts for the allowed range of pitch, major and minor diameters for classes 6H and 6g. The values are calculated from the definitions of ISO 965-1. They have limited use since they provide data only for the default classes.

Apr 3, 2024 · m10-6h是一公制内螺纹，m10是螺纹大径，螺距是标准的1.5, 6h是螺纹公差等级，一般没螺纹左后是字母表示为大写的“h”，外螺纹是小写的了。 m是螺纹代号， 一般螺纹按螺距可分为：粗牙和 细牙螺纹 两种。 m10：公称直径为10的 粗牙螺纹 。

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.

Jul 1, 2024 · 6H Tolerance (Internal Threads): The 6H tolerance is used for nuts or the internal threads of a bolt and nut assembly. It ensures that the internal threads fit precisely with the external threads. The ‘H’ designation indicates that the tolerance is on the higher side of the nominal diameter, ensuring a tighter fit.

M12-6H是一种螺丝的标注方式，其中M代表普通螺纹，12是螺纹的直径，6H是螺纹的公差。 具体来说，M12-6H的含义是：普通细牙螺纹，大径为12mm，螺距为1.25，中径顶径公差为6H的外螺纹。

Metric thread calculator to calculate external and internal metric thread dimensions including major diameter, minor diameter, pitch diameter and thread tolerance according to ISO 724 and ISO 965 standards.
