PSTD-028

Pack: F_OVERLAY Severity: major

Metric thread callouts must include tolerance class/position when ISO 965-1 is applied

Rule Card

Field	Value
Pack	F_OVERLAY — Industry Overlay and Compliance
Title	Metric thread callouts must include tolerance class/position when ISO 965-1 is applied
Severity	major
Check logic	Deterministic
Applies to	Compliance overlay
Inputs required	thread_callouts
Fix template	Update thread callouts to include tolerance class (e.g., 'M10x1-6H' internal, 'M10x1-6g' external) consistent with ISO 965-1 and the intended fit/function.

Short Description

Ensures metric thread specifications include tolerance class/position (e.g., internal 6H, external 6g) so manufacturing and gaging are unambiguous.

When It Applies

This rule runs only when an overlay activates F_OVERLAY. It targets Compliance overlay.
