Low head socket cap by the look of it..............a search for them should turn up a few in stainless, but if you mean they are the ones that hold the hangers to the frame, they don't look right to me........should be full head socket cap, shorter and no shank IIRC. On the other hand, I suppose they might be the ones that hold the zorsts cans to the hangers......which would explain the low head and the shank (low head sits in the ally cone shaped washer).......... I think they are all M8......... A4 Stainless M8 Socket Low Head Cap Screws (DIN 7984) A2 Stainless M8 Socket Low Head Cap Screws (DIN 7984)
Yep.....they hold the OEM cans on, so they are low head versions.........Just not sure about the thread / size (M8 or M10) because I don't have them on mine.....
