is a performance specification under the National Aerospace Standard (NAS) for a blind, self-plugging mechanical lock rivet with a protruding head . It is designed for high-strength, fatigue-resistant applications where only one side of the structure is accessible. The rivet provides a positive mechanical lock between the pin and collar, ensuring consistent clamp-up and vibration resistance.
While specific details about NAS-1830 are scarce, its mention often relates to the early adoption and utilization of UNIVAC I systems. The project or contract likely involved the implementation of UNIVAC I for specific applications, possibly within government or large corporations, given the nature of early computing and the significance of the UNIVAC I. nas1830
The defining feature of the NAS1830 is its . During installation, this shank is pressed into a pre-drilled hole in a panel or circuit board and then flared or "swaged" to lock it in place. This creates a permanent, high-strength attachment that eliminates the risk of hardware falling into sensitive electronics. Key Specifications is a performance specification under the National Aerospace
