A TUBTARA® blind rivet
nut is a mechanical fastener that ensures
a strong thread in a thin sheet and is used
in applications where there is little or
no access at the rear.
It can be used to clinch separate sheets
together (acting as a rivet) and allows
you to assemble another component with a
bolt or screw.

Cold Forming Division
In 1954 Dejond launched its first Tubtara® blind
rivet nuts, machined on a lathe. Only 10 years
later the production started specializing in cold
forming technology. Today Dejond offers one of
the widest, cold formed ranges of high quality
blind rivet nuts in the world, all manufactured
in its ISO 9001/2000 certified production facility
in Wilrijk (Belgium).
The Tubtara® programme includes standard and
special products in stainless steel 304 &
316, steel and aluminium.
The entire cold forming team is more than ever
committed to meet the challenges that lie ahead.
By manufacturing in an environmentally friendly
way, it tries to minimalize the influence of its
activities on the environment and create a balance
between economical, social and environmental aspects.
Together with its focus on R&D, Dejond wants
to reach the highest quality ever.
In that respect Dejond's management decided to
further uplevel the Tubtara® range by investing
in a new advanced machine-unit. New developments
and more difficult parts will gradually be introduced
as from 2010.
Dejond has the ambition to stay at the
forefront of the design and manufacture of blind
rivet nuts.
Through short delivery times and a strong technical
& commercial support, Dejond tries to give its
partners-distributors the opportunity to gain
new applications worldwide. Thanks to its flexible
stock availability & central location near the
port of Antwerp & Brussels airport, customers
of all continents receive their Tubtara® blind
rivet nuts at short notice.

| Installation |
|
|
 |
 |
|
|
Introduce the Tubtara® mounted on the setting
tool, into the hole
of the workpiece from one side. |
Set the Tubtara®. The deformation chamber
of the Tubtara® is now forming the counterhead
on the underside of the workpiece (bulb).
Unscrew the mandrel from the Tubtara®. |
The Tubtara® is set. Now you can easily
insert your bolt or screw to assemble another
component. |

Anti-rotation
solutions
There are different solutions to avoid the risk
on rotation and increase the torque-to-turn resistance:
| |
-
If you have an application in soft
material such as plastics or soft aluminium,
use our splined Tubtara®
versions. When the splines protrude
into the material during setting, your
Tubtara® won't turn into
the hole.
