ECSS-Q-ST-70-46C – Requirements for manufacturing and procurement of threaded fasteners (31 July 2008)

This Standard has been cancelled and replaced by ECSS-Q-ST-70-46C Rev.1 (6 March 2009).


This Standard defines the requirements for manufacturing, provision, inspection and quality control of high­quality threaded fastening devices (bolts, nuts, studs and screws) hereafter referred to as threaded fasteners or fasteners, used in space hardware.

This Standard does not include a complete review of the factors relevant to the fabrication of high quality threaded fasteners. It provides the definition of the technical requirements and quality control procedures to be applied in the fabrication and supply of threaded fasteners for spacecraft applications.

Fasteners for spacecraft applications are those aerospace standard fasteners (i.e. in conformance with LN, DIN or other national or international aerospace standards), or those fasteners meeting or exceeding the requirements in ISO.
