BS Fixings can supply rivets with a stainless steel body and steel mandrel or formed completely from stainless steel, each with a generous grip range of between 6mm and 15mm. We use Grade A2 (304) stainless steel to fabricate our dome head blind rivets and a full range of sizes - from 3.2mm to 4mm - is now available for immediate despatch from BS Fixings in convenient boxes of 100 stainless steel rivets.
