Thin castellated nut

Scope and limits

Shape screening for thin castellated nut. Exact dimensions, thread and mechanical properties remain unverified. Selected standard reference: DIN 937:1983-12 (withdrawn).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 937:1983-12

Thin castellated nut

Source scope
Metric thin castellated 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.
