The M0664 series from RAF Electronic Hardware, Inc., consists of metric round metal spacers and standoffs designed for various mounting applications. These components are essential for creating reliable electrical connections and maintaining proper spacing between components on printed circuit boards (PCBs). If you're working on projects that require precise spacing and mechanical support for components, these spacers and standoffs are a go-to solution.

One thing worth noting is their versatility—they can be used in both through-hole and surface-mount applications. This makes them suitable for a wide range of electronics projects, from hobbyist builds to industrial equipment. Engineers tend to reach for these spacers and standoffs when they need to ensure that components are securely mounted without compromising the overall design or functionality of the system. They help prevent soldering issues and improve the durability of the assembly by providing consistent spacing and support.
