What is 5g tolerance?
The 5g indicates the tolerance class for the pitch diameter and 6g is the tolerance class for the major diameter. A fit between threaded parts is indicated by the nut thread tolerance designation followed by the bolt thread tolerance designation separated by a slash.
What is the standard metric thread tolerance?
ISO Metric Thread Tolerance Tables
| Table 3: Major Diameter Tolerance of External Metric Threads (Td) | ||
|---|---|---|
| Pitch | Tolerance Grade | |
| 0.35 | 0.053 | 0.085 |
| 0.4 | 0.060 | 0.095 |
| 0.45 | 0.063 | 0.100 |
What does M5 0.8 mean?

| Metric | Closest Inch |
|---|---|
| M3.5-0.6 | 6-40 (Same) |
| M4-0.7 | 8-36 (Larger) |

What is 6H tolerance class?
A class of thread fit roughly equivalent to 2A/2B is “6g/6H”, which means an external thread with tolerance grade of 6 and position g, and an internal thread of tolerance class 6 with position H. “4h6h/4H5H” is a class of thread fit used for some aerospace fasteners, and is roughly equivalent to 3A/3B.
What does m8 6H mean?
m8 means metric thread 8mm of ISO standard and 6H refers to tolerance of threaded hole (know more about it in ISO 2768)
What does 6H tolerance mean?
6H is tolerance for internal thread. Jaswant P R 25 Jan, 2018 02:31 PM.
What is thread tolerance?
Screw threads are usually signified by two tolerances. One is for the maximum outside diameter, measured from the major diameter of the thread, and the other is for the pitch diameter, measured from the midpoint of each tooth. Dimensions in millimetres (mm). Tolerances 6g (6h).
What does M14x1 5 mean?
Determine the diameter of the bolt by looking at the first number. For example, if the metric bolt was M14x1. 5×25, it would have a diameter of 14 millimeters.
What is the M in bolt size?
The letter ‘M’ indicates that this bolt uses a metric thread. The number ‘8’ refers to the nominal diameter of the bolt shaft in millimeters. The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters. And the final figure, 20, is the length in millimeters.
What does 6H mean on a thread gage?
The first 6H refers to the Pitch Diameter tolerance. The second 6H refers to the minor diameter tolerance. Because screw thread plug gages do not look at the part minor diameter, the use of the minor diameter tolerance is irrelevant when considering the gage design parameters.
