  • Rancilio silvia grouphead screw mod where to buy?

    Anyone know were I can buy a M5/12mm stainless steel screw for this mod? Ive looked online and all the screws listed are only #304 grade not #316. It is not the sort of thing bunnings stocks.

      Thanks for the link Mal, have been looking at doing this mod with my Silvia.
      Price of screw- 39c
      Postage- $12.90 (ouch!)
      Might try looking around Brissy to pick one up. At least now know exactly which screw to buy.

        Try looking in a yacht supply shop - they may stock them. I used a flattened mushroom head with a hex socket. Makes it very easy to get off.

          Gday Paul,

          Ive bought small quantities from them before and after talking to them on the phone, they were happy to send in an envelope or what have you, for about $2.00. Still a lot to pay compared to the price of a single screw of course but when you live out in the bush a bit, you get used to having to deal with that sort of thing....

            I got mine from a local stainless steel bolt comp. Try yellow pages, brissy should have one.

              Since when was Warwick "the bush"???? I guess there arent too many hardware stores down that way, but still.

                    Is the button head one better than the countersink one for the mod? Bit worried the countersink will damage the screen with repeated removal. And no it is not because it is 6c cheaper.

                      It will still protrude into the puck but not as bad as the standard one..

                      Get a couple of each ;D

                        The BHSS will work fine Newbie, I replaced the screw in my Silvia with something similar about 8 years ago, made removing the screen a breeze and had no impact on dosing or the quality of shots.

                          Try a specality fastener store. Ask for a 316 button head cap screw.

                          That said, a 304SS will be just fine in this case. The ~2% less nickel content shouldnt affect the anti-rust properties of the screw itself.

                          As for a store in Qld, Blackwoods would be a pretty good bet. In Vic try Fastener King out in Dandy, ACT use Specialty Fasteners (http://www.specfast.com.au/), SA use United Fasteners or Coventries, and in NSW Blackwoods are good as well as there are a ton of smaller joints in the west part of Sydney.

                          Oh and if you are still having issues, im heading out to Coventries later this week, i could pick up 10-50 of them and post them to people for a minimal donation to a charity or something.

                            ummm...i saw this thread and may be a little late- i have a silvia and also dug up some m5x12mm recessed screws which were in my bike bits box. i tried to do the swap over but 12mm seemed a little too short as the screw needs to reach past the water distributer of the silvia - i measured the screw in there and i think it stands at 16mm - so an m5x16 might be the go? -or i might of just stuffed up - how did you guys go on the 12?

                              Depends if its countersunk or not. A M5x12 countersunk bolt will be the same as a M5x16 button or hex head. The length is the length of the thread.
