    Rancilio Silvia shower-head bolt replacement ?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight

    the shower-head bolt on my Silvia is leaving a deep imprint on the puck.
    Has anyone tried to replace it with a flat head (phillips counter-suck head?) shower-head bolt?

    verdict ? does it improve the espresso or not worth the effort ?

    also, assuming its worth-while - what size bolt is it (gauge, length, metric, empirial, etc) and where can i buy it?
    I am in Melbourne.
    I tried a couple of local hardware stores - no luck.

    Hey mate,

    Don't know how much of a difference it has made but I've done the mod and haven't had any problems with it so far. I bought the screw from site sponsors Coffee Parts | Spare Parts and Accessories for Espresso Coffee Machines and Grinders

    Any bolt shop will have one, I got two from my local, stainless 316 cheese head phillips, size and thread, take yours with you. Mind you it is necessary to chamfer the disperser, in a lathe to take the new screw. NOt hard any little engineering shop will do.
