M4 thread stud. Used in the Brasilia Club and Lady models, as well as the Gaggia Carezza, Classic and Evolution for brewing temperature regulation. KSD301-P. Gaggia #DM1168. Take care to not over-tighten!

(or “grease” - not included) aids heat transfer between the thermostat and contact surface by filling in microscopic imperfections in the metal surfaces. It is especially useful for pipe mount applications.

A key characteristic of this synthetic thermal grease is it’s long-term material stability. That means it won’t harden, dry out, or melt in normal industrial use.

Smear some paste on the sensing head of the thermostat switch prior to threading it down. (Not to be used as a glue.)
