Organization: ISO
Publication Date: 22 September 2020
Status: active
Page Count: 8
ICS Code (Metric screw threads): 21.040.10
scope:

This part of document specifies limit deviations and limits of sizes for the pitch and crest diameters of the hot-dip galvanized metric external screw threads conforming to the coarse thread series of ISO 262 (from M10 to M64) having a basic profile according to ISO 68-1.

This part of document is applicable to the hot-dip galvanized metric external screw threads to mate with the internal screw threads tapped with tolerance position H or G after galvanizing.

Products made with thread tolerances in accordance with ISO 965-4 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 ISO 965-4 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.

NOTE After the hot-dip galvanization the external threaded products with the tolerance class 6az shall be centrifuged immediately.
