STAINLESS STEEL DOME RIVETS ISO 15983

Dome Rivets ISO 15983 — A dome-head blind rivet is a two-part fastener - a hollow body and a mandrel running through its centre - that forms a permanent, non-threaded joint from one side of the work only, making it the standard choice wherever the back of the joint is inaccessible, such as closed box sections, cladding, or enclosures. Pulling the mandrel through the body draws the far end outward into a second head, clamping both sheets together; once set, the joint can't be taken apart without drilling the rivet out, so it's suited to permanent assembly rather than anything needing future disassembly. The dome head itself sits proud once installed, giving a larger bearing surface and generally a stronger grip against pull-through than a countersunk equivalent of the same shank diameter, which makes it the more robust option wherever head profile isn't a constraint. Sizing a blind rivet comes down to two things: shank diameter, chosen for the shear and tensile load the joint needs to carry, and grip range, which has to span the full combined thickness of the materials being joined - too short a grip range and the mandrel snaps before the far head has fully formed, leaving a weak or loose joint. On grade, both body and mandrel material matter: A2 stainless is generally adequate for general engineering, automotive, and construction use indoors or in typical outdoor exposure, while A4 is worth specifying for marine environments, coastal buildings, or where the joint will see regular washdown or chloride exposure, since A4's molybdenum content resists pitting corrosion considerably longer than A2. It's also worth matching rivet grade to the parent material where dissimilar metals are being joined - a stainless rivet set into aluminium or galvanised steel in a damp environment can set up galvanic corrosion at the joint if the combination isn't considered. ISO 15983 governs the body and mandrel dimensions, head form, and grip range for this dome-head pattern, keeping rivets from different manufacturers interchangeable within a given size.

FAQs
How does this compare to the countersunk rivet, ISO 15984?
A dome rivet leaves a raised, rounded head on the visible face; a countersunk rivet finishes flush, requiring a countersunk hole.

Can a dome rivet joint be disassembled for maintenance?
No - like all blind and solid rivets, the joint is permanent once set and has to be drilled out to separate the parts, so a bolted or nutsert-based fixing is the better choice wherever the joint may need to come apart again.

Does the mandrel material need to match the rivet body grade?
Not always - check whether the mandrel is stainless or plated steel, since a steel mandrel snapped off close to flush can leave a small corrosion-prone point at the centre of an otherwise fully stainless joint.
