The "M in a square" logo is the official manufacturer's stamp of Marussia F1 Team (later Manor Marussia), confirming that your red wheel nut belonged to one of their cars between 2012 and 2015. It would have been used, removed during a pit stop, cleaned, subjected to crack-testing (Non-Destructive Testing), and thrown right back into the active rotation pool for the next session or race.
