are high-precision electronic hardware components manufactured strictly to National Aerospace Standards (NAS) developed by the Aerospace Industries Association (AIA) . They function primarily as structural separators in stacked Printed Circuit Board (PCB) sub-assemblies, avionics enclosures, and aluminum panels. Unlike standard threaded spacers that require independent mating hardware on both ends, swage standoffs feature an unthreaded cylindrical shank. This shank is permanently deformed or flared directly into a pre-drilled panel. This design prevents fastener loss, reduces component count, and ensures robust resistance to high vibrations. 🛠️ The Mechanics of a Swage Standoff

NAS swage standoffs are high-precision, permanent fasteners designed for aerospace and defense applications. These components are used to create fixed distances between stacked printed circuit boards (PCBs) or panels, preventing components from touching while ensuring stability under vibration. Unlike standard standoffs, swage versions are permanently attached to a board through mechanical deformation, which prevents them from being lost or dropped during later assembly stages.
