ISO general purpose metric screw threads - Tolerances - Part 5: Limits of sizes for internal threads to mate with hot-dip galvanized external threads with maximum size of tolerance position h before galvanizing (ISO 965-5:2025)
Abstract
This document specifies fundamental deviations and limits of sizes for pitch and minor diameters of ISO general purpose metric internal 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 metric internal threads oversized to tolerance class 6AZ or 6AX to mate with hot dip galvanized external threads with maximum size of tolerance position h before galvanizing. This document is not applicable to internal threads with coating on thread surface. The limits of sizes before coating are decided by agreement between manufacturer and purchaser.
