STRUCTURAL RIVET (Steel, Aluminium and Stainless Steel).

Structural high strength fastener, designed to be used in single-sided structural applications with heavy loads. Bralo Structural rivet is synonymous with security and performance.


Bralo Structural Rivet is designed to fix elements where a high resistance to both tensile and shear strengths are required. This fastener has been designed for heavy-duty fastening applications and ensures a quality fastening.

Due to its feature of adaptive expansion, the same size can be used for different thickness. This rivet guarantees a homogeneous riveting whatever the thickness, and ensures the locking of the mandrel inside the head, obtaining thus a great tightness.


  Features and benefits.  

  • High tensile and shear strength.
  • High tightness. The joints are completely watertight.
  • Multi-grip range feature. Being a multigrip rivet, it offers the possibility to work in a big variety of grip ranges. Just two sizes of this rivet covers a grip range from 1 to 16 mm, reducing the number of rivets to be stored.
  • Single-side access.
  • The hole is completely filled through a radial expansion of the rivet. It allows to compensate uneven, misaligned, oversized or grooved drills.
  • Firm and high-quality joint, vibration-resistant due to its internal mandrel locking.
  • High resistance mandrel. It allows rapid assembly of parts with large separations.
  • Versatility. Just one size can be used to replace several rivets with standard grip ranges.
  • Excellence and durability.
  • It requires simple, fast and lightweight tools.

Technical characteristics.

Materials:Aluminium, Steel and Stainless steel

Diameters:4.8 mm, 6.4 mm & 9.7 mm.

Heads:     Dome and Countersunk 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.

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 Structural Rivet is available in an infinity of lacquering and in any kind of colour. From black to white, we have a range of over 50 RAL colours and we can make special lacquering under request.

Bralo aluminium structural rivet can be anodized and it is also available with an organic coating (Delta-Seal, Delta-Protekt, etc.) that achieves a greater strength and durability. Both finishes protect aluminum from abrasion, corrosion, and the anodising allows it also to be tinted in a wide variety of colours.

Another option is the zincating, which is only available for the steel rivets. Zincating is a zinc coating that not only protects steel from oxidation and corrosion, but it also improves the visual aspect of the item. Depending on the required strength in each application, there are various available zincating options: the galvanic one, where the zinc is the only metal that forms the suffering layer and the nickel zincating, with a resistance twice as high as that of the normal zincating, making it suitable for automotive and weather resistant applications. The latter is also available in a transparent, shiny look that can be silver and black.

Aluminium Lacquering, anodising and organic coating.
Stainless steel Passivation and lacquering.


At  Bralo we can make custom designs adapting to the specific needs of every application. Please contact us, should you need more information about special finishes.
