AEROSPACE FASTENERS

             The domestic in common use aerospace's buttonning up a piece be an iron casting creation, its machine function should match 《steel pipe scaffold the aerospace button up a piece (GB15831-2006)》the material is no lower than KT330-08.But the aerospace button up a species good people and bad people mixed up, quality on the market currently not even, the factory house for have usage ash iron casting, ground slot steel to creation the aerospace button up a piece, its machine function be not hard to satisfy request according to nation standard produce.Some unit crave for cheapness and make low price the inferior aerospace button up a piece into a construction the spot.Moreover, some unit Shu is at the management, the aerospace button up a screw rust eclipse, slippery silk still usage, cause Ning tight the dint Ju could not reach provision request.
              The aerospace button up a piece is a conjunction steel rail and track Zhen of in the center coupling spare parts.Its function is steel rail fix on the track Zhen, keep gauge and arrestment steel rail opposite at the maneuver of track Zhen to move.At concrete track the orbit of the Zhen up, because of the flexibility of concrete track Zhen more bad, the aerospace button up a piece to still need to be provide enough of flexibility.Is this, the aerospace button up a piece and have to have enough of strength, durable, with certain of flexibility, also the effect keep steel rail and the credibility of the of track Zhen coupling.In addition, also the request aerospace button up a system spare parts little, install simple, easy to dismantle to unload.
