SEALED RIVET (Aluminium, steel, stainless steel and copper).

Fastener element available in a wide range of materials that ensures both water and air tightness. Bralo Sealed Rivet is synonymous with safety and confidence


The sealed rivets are break mandrel blind rivets that guarantee a solid and high quality fastening. The joints are completely sealed to fluids, avoiding leakage of liquids or vapors due to the locking of the mandrel inside the rivet body.

Bralo Sealed Rivet is available in a wide range of diameters, from 3.2 mm to 6.4 mm., covering a wide grip range (0.5 mm to 20 mm).

Along the same line, the materials variety is huge and so are the finishes options: from lacquering to the different protective coatings, the customisation possibilities for this rivet are endless.


  Features and benefits.  

  • Single-side access (blind rivet).
  • Great tightness. The joints are completely sealed to fluids, avoiding leakage of liquids or vapors
  • It covers a wide range of thickness to be riveted, from 0.5 mm to 20 mm.
  • It can fasten different materials with different types of manufacturing.
  • Diversity. It is available in a wide range of materials: aluminum, steel, stainless steel, copper, etc. , with three different types of head: dome, countersunk and large heads.
  • Wide rangeof diameters from 3.2 mm to 6.4 mm.
  • The mandrel is completely locked within the head, avoiding electrical problems or pounding.
  • It does not deform surfacesafter the riveting process is finished (painted, glazed, etc.).
  • Good performance with temperature variations.
  • It does not come loose from dynamic stress (vibrations in general)
  • Available with rings or neoprene gaskets for an even better sealing.
  • Fast, simple and great quality assembly.
  • It requires simple, fast and lightweight tools.

Technical characteristics.

Materials:Aluminium, steel, stainless steel and copper.

Diameters:3.2 mm., 4.0 mm., 4.8 mm., 5.0 mm. and 6.4 mm.

Heads: Flat, countersunk and large heads

Dome Head
It is the most versatile type of head. It provides enough bearing surface to retain all kinds of materials, except those extremely smooth and brittle.
Countersunk Head
This type of head allows the riveting of a bigger thickness and it is designed to obtain a flat surface, free of projections.
Large Head
It provides double the bearing area compared to the dome head one and offers a great resistance. They are designed for applications where a soft or brittle material must be assembled to a rigid support material.

Bralo have no limits when it comes to variety. Our intensive search for materials and our constant use of innovative technology have established the widest range of finishes in the market.

Bralo Sealed Rivets are available in an infinity of lacquering with liquid epoxy painting. From black to white, we have a range of over 50 RAL colours and we can make special lacquering under request.

For a maximum corrosion resistance and durability of our steel rivet, we can apply different protective coatings, whether zincating or organic coatings such as Delta or Delta-Seal Protekt. For the aluminium rivet , apart from the organic coating, we also have the anodising, which protects the rivet from abrasionand corrosion and allows it to be tinted in a wide variety of colours.
