Nas61 | Spacers

Introduction In aerospace and high-performance military applications, the integrity of a bolted joint is only as strong as its weakest component. While bolts and nuts receive the majority of engineering attention, spacers, standoffs, and bushings are critical in managing load paths, maintaining alignment, and preventing galvanic corrosion. Among these, the NAS61 specification stands as a premier standard for precision, close-tolerance spacers.
