HARD GRIP RIVET (Steel and Stainless Steel).

Tight and high resistance fastener, designed for use in single-sided applications. Its large bearing area on the blind side makes this Hard Grip Rivet ideal for applications with hard plastics and thin sheets.

Description

Bralo Hard Grip Rivet is designed for the most demanding applications that require a great clamping force and high tensile and shear strengths.

Due to its feature of a wide expansion on the blind side, both the torquing and the load forces are well distributed. It is therefore particularly suitable for the work with hard plastics and thin sheets of metal.

Its unique grooved mandrel design allows the head of the rivet to be completely held inside the body due to a mechanical locking, avoiding thus any kind of electrical problems and noises. It allows a homogeneous riveting, a solid and high quality joint that resists all kinds of vibrations.

Finishes

One of Bralo’s commitments is to find different ways of meeting our customers needs. With this goal, we offer the widest range of finishes and coatings for this rivet in the market place.

To avoid the effects of external agents, the most appropriate finishes for the Bralo Hard Grip 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.

Bralo Hard Grip Rivet is also available, in any kind of material, 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.
