7、t of patent rights. DIN and/or DKE shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN 13-51:2005-08 as follows: a) additional items “thread pitch” have been added to Tables 2 and 4; b) the designation in Clause 5 has been slightly c
8、hanged; c) Annex A has been withdrawn and “interference fit” has been added to the scope; d) the standard has been editorially revised. Previous editions DIN 13 and DIN 14 Suppl. 14:1944x-03 DIN 13 and DIN 14 Suppl. 15:1944xx-03 DIN 13-51:1988-12; 2005-08 4 1 Scope This standard specifies the tolera
9、nce classes for external threads to be paired with internal threads of tolerance class “fine” (4H and 4H5H) as in DIN ISO 965-1. This pairing of threads aims to achieve an “interference fit”. NOTE Depending on the actual size of external and internal threads “interference fit” is often not achieved.
10、 If “inter-ference fit” is essential, application of DIN 8141-1 “ISO-metric screw threads; coarse pitch threads and fine pitch threads for interference fits in aluminium cast alloys; nominal diameter from 5 mm to 16 mm; nominal sizes, tolerances and limits of sizes” is recommended. 2 Normative refer
