Re: Silvia shower screen bolt
If Im right - and I checked what Coffee Parts has for the screw, then you need a...
M5X12 Button head socket screw (stainless - preferably 316 Marine)
Thats just for the screw out/screw in approach, not a true countersunk.

Re: Silvia shower screen bolt
Yep straight swap.. although I had to trim the length of the bolt a smidge. The local bolt supplies didnt have the exact same length in stainless steelOriginally posted by 636661677B686F090 link=1244028153/18#18 date=1244201768Was that just a straight out swap Gronk? No drilling etc?

Re: Silvia shower screen bolt
I used to get a fair bit of channelling when I first got my Silvia and decided to swap the giant Frankenstein bolt to a domed one with a lower profile and the channelling ceased instantly.
No more fractured pucks

Re: Silvia shower screen bolt
The screw only needs to be done up finger tight using a screw driver and the tips of your fingers. Do up till it just nips.

Re: Silvia shower screen bolt
I read somewhere (I wish I could remember!) that the screw should only be a little more than finger tight. This is how tight I did mine up and found no issue with that. It probably is a good idea to do it that loose as it is much easier to get off and should reduce the chance of stripping.Originally posted by 253A30213C323E3621530 link=1244028153/14#14 date=1244148579I think so but there is no need to have it that tight, and if the shower screen is removed for cleaning it wont gunk up.
For me I found it reduced Channeling and the transition to blonding was easier to pick.
For me it didnt reduce channeling or anything else. I still would highly recommend the mod as it is easy, cheap and the parts to reverse the process are cheap and easy to get. Also others have found a positive effect.
It do one thing for me, it took out a variable in my mind. In other words I didnt have to question whether the bolt was causing channeling or not.

Re: Silvia shower screen bolt
Yes there is how to link is HereI thought some drilling or pressing was also involved
I think so but there is no need to have it that tight, and if the shower screen is removed for cleaning it wont gunk up.Maybe they use the hex head so it can be removed easier if you cant get to it with the screwdriver due to stripping

Re: Silvia shower screen bolt
My new Silvia 09 has the hex head bolt on the shower screen. Noticing slight impression on the puck but not enough to bug me yet because the shots that come out of this thing are heavennn. Maybe they use the hex head so it can be removed easier if you cant get to it with the screwdriver due to stripping. My Gaggia Deluxe had a flat philips screw for the showerscreen and needed a philips head. Result is I stripped it bad once trying to remove it and that shower screen never came off
. Maybe that was a good thing otherwise I wouldnt have the Silvia now ;D

Re: Silvia shower screen bolt
take bolt out, take to bolt shop. find a suitable screw and buy with money or steal. go home and fit and enjoy unprinted pucks.

Re: Silvia shower screen bolt
If not just buy a s/s cheese or button head screw from your local bolt shop.I hope mine will have the flat screw
I have had the c/sunk screw fitted for a while. A very effective mod at a minimal cost, a mod I regard as being right up there a with PIDs and commercial baskets.

Re: Silvia shower screen bolt
hi
as chris said
some of the silvias came with a flat head screw. this screw has been used for years in their commercial machines.
i prefer the flat head opposed to the bolt style
