ISO metric screw threads - Specification for selected limits of size Ingestion-build-201039 Planning of highly accelerated testsThis British Standard, a part of the BS 3643 series, specifies the fundamental deviations, tolerances and limits of size for the tolerance classes 4H, 5H, 6H and 7H for internal threads (nuts) and 4h, 6g and 8g for external threads (bolts) where appropriate for: coarse pitch series within the range 1 mm to 68 mm diameter fine pitch series within the range 1 mm to 33 mm diameter constant pitch series within the range 8 mm to 300 mm diameter.
