Abstract

This document specifies fundamental deviations and limits of size for pitch and major diameters of hot dip galvanized metric external threads (M) conforming to ISO 262 (M6 to M68 with coarse pitches and M72 to M100 with pitch 6) having basic and design profiles in accordance with ISO 68-1. This document is applicable to hot dip galvanized metric external threads undersized to tolerance class 6az before galvanizing to mate with internal threads made to tolerance position H or G after galvanizing.
