Application Summary AI generated

This standard specifies the dimensions, technical requirements, and testing methods for self-locking single lug anchor nuts with counterbore and MJ threads, used in aerospace applications. It is applied in the assembly of aircraft and spacecraft structures where reliable, vibration-resistant fastening is required in confined spaces, such as in fuselage panels, wing attachments, and engine mounting systems. The standard ensures compatibility with MJ-threaded bolts and provides consistent locking performance under extreme temperature and load conditions typical of aerospace environments.
