I was looking for hose clips for my silicone hoses, I had some for holding a stainless steel braiding in my old kettle, but I noticed that its rusted, so I'm not getting them from a hardware store again.
I got some from the hbc but they're not the ones they show on the website (open worm drive vs closed) and looking at geterbrewed (http://www.geterbrewed.ie/jubilee-hose-clips-16mm-27mm/) a reverse image shows that they're zinc plated steel and not stainless, but they might just be using that photo.
But it led me to here https://www.hcl-clamping.co.uk/ (https://www.hcl-clamping.co.uk/) and they have these (https://www.hcl-clamping.co.uk/75-worm-drive-9mm-mikalor-304ss) and they're fully stainless steel including the screw. They're more than half the price of any fully stainless steel ones I could find in Ireland http://www.chmarine.com/acatalog/hose-clip.html#SID=43 (http://www.chmarine.com/acatalog/hose-clip.html#SID=43)
