Use this tolerance class for commercial external bolt threads. Already Subscribed to this document.
We have no document history for this standard. External thread minimum major diameter [d min ].
Tolerance Class for Nut. For coated threads, the tolerances apply to the parts before coating, unless otherwise stated. This standard is not included in any packages.
The user shall use 6g for bolts and 6H for nuts unless there is a specific requirement to use other tolerance classes. Tolerance class can be selected among the alternatives 6e, 6f, 6g and 4h for bolts and 5H, 6H, 7H and 6G for nuts. Your Alert Profile lists the documents that will be monitored. Internal thread minimum minor diameter [D 1min ]. Pitch diameter tolerance of internal thread.
kso In addition to basic size calculations of metric threads, tolerance calculations of different tolerance classes can be done according to ISO External thread maximum pitch diameter [d 2max ]. In general engineering use, calculations can be done by selecting a standard metric thread size from the list which contains metric thread sizes in the diameter range from 1.
Need more than one copy? The maximum diameter of a thread which is diameter of the crest of a male thread or root of a female thread. External thread minimum truncation [C min ].
The theoretical isl of a screw thread in an axial plane defined by 965-22 dimensions and angles common to internal and external threads. External bolt thread root profile is given the “Definitions” section.

For external bolt oso The actual root contours shall not at any point transgress the basic profile. Thread basic minor diameter [d 1D 1 ]. If the document is revised or amended, you will be notified by email. The list of metric screw thread used in general engineering applications are given in the General Purpose Metric Screw Threads Table.

After coating, the actual thread profile shall not at any point transgress the maximum material limits for positions h or H. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. External thread minimum minor diameter [d 3min ]. The surface at the top of the ridge connecting its two flanks.
General Engineering Use Custom Use. External thread maximum truncation [C max ]. The minimum diameter of a thread which is diameter of the root of a male thread or crest of a female thread. Minor diameter tolerance of internal thread.
Thread basic pitch diameter [d 2D 2 695-2. We have no amendments or corrections for this standard. Fasteners of property class 8. Please first log in with a verified email before subscribing to alerts.
