Abstract
Overview
ISO 965-1:2026 defines the tolerance system for ISO general purpose metric screw threads (M), building upon the basic and design thread profiles standardized in and metrics defined in . As Part 1 of the series, this standard introduces the principles and basic data for specifying pitch, crest, and root tolerances crucial for ensuring proper thread fit, function, and interchangeability in mechanical assemblies.
