Bibliography

Describes the fundamental deviations, tolerances and limits of size for the tolerance classes 4H, 5H, 6H and 7H for internal threads and 4h, 6g and 8g for external threads.

This part of this BS3643 specifies the fundamental deviations, tolerances and limits of size for the tolerance classes 4H, 5H, 6H and 7H for internal threads and 4h, 6g and 8g for external threads where appropriate for:

a coarse pitch series with the range 1mm to 68mm diameter;
a fine pitch series with the range 1mm to 33mm diameter;
a constant pitch series with the range 8mm to 300mm diameter.

For certain diameter/pitch combinations, the fundamental deviations, tolerances and limits of size for tolerance class 4H for internal threads and tolerance classes 6h and 4g for external threads, primarily for aerospace use, are specified in AnnexA.
