These diamond crusted washers add copious amounts of friction to avoid loosening of critical engine components found on many Ford and Mazda engines.  Typically one between the crank pulley and the cam timing chain drive pulley and one between the crank pulley and crank bolt, but also another on the multi piece mazdaspeed engine timing gears.  Mazda engine also typically use them on the cam gear bolt position.  

A better solution is to key your crankshaft and timing chain drive gear
