  • The purpose of this document is to introduce the localized development procedure for socket head cap screw used for satellite application. For localized development and verification of socket head cap screws, manufacturing process was composed of head forming, heat treatment, rolling process and surface treatment to meet aerospace hardware requirements based on MIL-B-7838, ECSS-Q-70-46A and KS W 8168 aerospace specification. In order to verify the quality and performance of localized screw, several kinds of qualification tests are successfully completed. By comparing the quality and performance for the localized screws and the same size oversea-procured screws, we can sure that localized socket head cap screws have good quality performance enough to use for aerospace application.
