10 sets M3 * 30 hexagonal standoffs mounting kit

A 10-pack of M3 × 30mm hexagonal standoffs with matching screws and nuts. Use them to mount circuit boards, sensors, and other components with consistent 30mm spacing and secure mechanical support.

The male/female design allows standoffs to be stacked for even greater clearance. At 30mm height, they provide generous room for taller components, heat sinks, or multi-level board configurations such as robot chassis builds.
