where

es is expressed in micrometers;

P is expressed in millimeters.

Products made with thread tolerances in accordance with this part of ISO 965 may show failure at lower ultimate tensile loads than those specified in ISO 898-1 due to reduction of the stress area.

External screw threads with thread tolerances according to this part of ISO 965 must not be mated with internal screw threads with thread tolerances according to ISO 965-5 because such combinations will create severe risk for thread stripping.

The limits of sizes for the tolerance quality specified are derived from tolerances specified in ISO 965-1.

The fundamental deviations for internal screw threads with a tolerance position AZ have been calculated according to the following formula:

EIAZ = + (300 + 20P)

Where

EI is expressed in micrometers.

P is expressed in millimeters.

The fundamental deviations for internal screw threads with a tolerance position AX have been calculated according to the following formula:

EIAX = + (220P - 20)

Where

EI is expressed in micrometers;

P is expressed in millimeters.

Products made with thread tolerances according to this part of ISO 965 may show load failure when tested in accordance with ISO 898-2 without adjustment of the other mechanical properties.

Internal screw threads with thread tolerances according to this part of ISO 965 must not be mated with external screw threads having thread tolerances according to ISO 965-4 because such combinations will create severe risk of thread stripping.

NOTE Internal screw threads with tolerance class 6AZ are primarily intended to mate with external screw threads centrifuged after hot-dip galvanizing.

Internal screw threads with tolerance class 6AX are primarily intended to mate with hot-dip galvanized external screw threads with heavy coating not centrifuged.
