DeLOCK Standoff M4 x M3, hexagon, inside / outside, 20 mm black 4 pcs

These standoff spacers by Delock can be used for secure mounting of PCBs to create a fixed distance between a printed circuit board and other components. By separating the PCBs from other components, the spacers allow a better ventilation and offer an optimal resistance to high temperatures, e.g. inside of a PC case.
