Space Exploration

The Special Fasteners requirement for the Space Exploration and Satellite sector are precise with strict adherence to specifications and the recording of dimensional data with high quality workmanship. Full material traceability is usually specified from materials originating within the European Union. A prompt delivery is usually required and in some cases prototypes are requested prior to delivery of the bulk. Non-disclosure agreements are also quite common.

The materials selected are those that offer some strength over weight advantage and therefore production methods such as thread rolling is utilised. In addition, like Formula 1 any residual swarf or loose metal chippings are of concern therefore wire or spark eroding operations are sometimes used. Alloys usually range from strain hardened austenitic, super austenitic or duplex stainless steels. Aged hardened titanium alloys are also regularly specified with some nickel alloys in certain circumstances.
