Retainer Screw for Rotax Max Evo Kart Engine thermostat mechanisms. This screw is designed to hold the retention bracket in place during operation of the thermostat and the engine.

Each screw is a 'taptite' type screw, meaning that it is not removable / replaceable multiple times- a new screw must be used to replace the screw each time the thermostat mechanism is exchanged.
