Scope and limits

Shape screening for regular hex nut. Exact dimensions, thread and mechanical properties remain unverified. Selected standard reference: ISO 4032:2023. Profile: nut; head/body form: hex; drive: external; thread series: Coarse. These are selected family attributes; geometry does not identify a product standard. A declared nominal size from 0.5 to 100 mm is required; optional pitch and thread length must be positive, with pitch below nominal size. These are input limits, not normative dimensional tables.

Source scope
Metric regular hex nut. Selected by the user; geometry does not identify a product standard.
Implementation in Prufi
Family shape screening and declared-input consistency only. All dimensional bands are Prufi heuristics, not normative dimensions. Thread geometry, tolerances, material, mechanical properties and complete conformity are not verified.
