Abstract
Overview
ISO 12256:2002 - "Aerospace - Drives, internal, cruciform, ribbed - Metric series" - is an international standard that specifies the dimensions and tolerances for metric internal cruciform ribbed drives used in aerospace screws. It covers drive geometries for screws with nominal thread diameters from , provides configuration drawings (Figures 1–4), and tabulates dimensional data (Tables 1–4). Dimensions and tolerances are expressed in and location tolerances follow .
