Those aluminium spacers and their screws and nuts will hold your modules and plates together.
The spacers come in packs of four, so that each pack will let you mount one module. We provide four screws and four nuts to go with the spacers so this is a complete mounting kit for one module.
The screws, nuts and spacers use standard 4-40 threading. The spacers are 5/16" long.
