Fasteners

The screws an owner meets

Rancilio's parts list gives a size for one fastener only, the boiler screw. Everything else is from its drawings, retailers or owners, as marked. No source gives a cross-head size, and none mentions Torx on any Silvia.

Inside: boiler, valves and pump

No torque figures are published for any fastener. Spanner sizes come from single videos, most of older Silvias, as marked.
