Scope and limits

Shape screening for hex coupling nut. Exact dimensions, thread and mechanical properties remain unverified. Selected standard reference: DIN 6334 (legacy catalog designation) (withdrawn). Profile: nut; head/body form: hex; drive: external; thread series: Either. 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.

Standards and references

DIN 6334 (legacy catalog designation)

Hex coupling nut

Source scope: Metric hex coupling 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.
