緊固件解決方案專家
產(chǎn)品介紹：
由于在航空航天結(jié)構(gòu)中使用復合材料越來越多，NAS1900鉚釘已成為許多設(shè)計中選擇的緊固件。 Cherry®1900使用可用的Cherry Shift Washer進一步改進了此設(shè)計，可以實現(xiàn)更一致的緊固件安裝和延長刀具壽命。 這種緊固件還利用了Cherry“One Tool Concept”來允許使用現(xiàn)有的工具，Cherry 1900形成了一個大的盲區(qū)足跡，使其適用于復合結(jié)構(gòu)，沖洗能力消除了剃須的需求，Cherry 1900 制造符合NAS1919和NAS1921規(guī)格，并提供各種尺寸和材料。
