Non-structural blind rivets

Hardvex rivet


description benefits materials technical characteristics combinations finishes download




HARVEX Rivet is a high-strength fastener system and can be used to replace several standard grip fasteners.



Our Hardvex rivet is synonymous with versatility. It is a fastener element made of an aluminium alloy that allows working with a great variety of grip ranges.

Due to its fastening feature of wide expansion on the blind side, the load and torque forces are well distributed. It is, therefore, especially suitable for working with plastics and thin metal sheets and it is often used for repairing.

Bralo Hardvex Rivet ensures a homogeneous fastening, a firm and high quality joint that is resistant to all kinds of vibrations. Furthermore, when properly fastened, it provides a tight seal against weather conditions.



Features and benefits

  • Multigrip feature. It allows working with a great variety of grip ranges. With just two sizes a wide grip range of 1 to 16 mm. is covered, reducing thus the rivet inventory.
  • Single-side access.
  • Mandrel locking feature, avoiding electric problems or pounding.
  • Good hole fill. It allows to compensate uneven, misaligned, oversized or grooved drills.
  • Versatility. Just one size replaces the grip range of several standard items.
  • Wide bearing area on the blind side, making it especially suitable to be used for applications with thin sheets and for repairing.
  • Solid and high quality fastening, resistant to all kinds of vibrations.
  • It requires simple, fast and lightweight tools.

Technical characteristics

Materials: Steel.

Diameters: 4.8 mm.

Heads: Dome 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.
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.

To avoid the effects of external agents, the most appropriate finishes for the Bralo Hardvex rivet are: zincating or an organic coating. 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 zincating, 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.

For a maximum corrosion resistance and durability of our steel rivet, we can apply different protective coatings, including organic coatings like Delta-Seal.


Steel Zincating

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