POLYGRIP® – A MOST VERSATILE SMALL FELLOW
The GESIPA® PolyGrip® range of blind rivets, originally
meant to be only a multigrip rivet has meanwhile shown
other multiple talents. This makes it a favourite choice for
difficult and demanding applications in industrial
environment. Whether in aluminium, steel or stainless
steel, outdoor or indoor, with hard or soft application
materials, critical hole diameters and tolerances, when
nothing seems to work properly, GESIPA® PolyGrip® will
usually save the day.
MAIN FEATURES
• Large grip range:
One single PolyGrip® blind
rivet can replace up to five
different sizes of standard
DIN blind rivets
Your benefits:
> Type simplification
> Limited type variety
for reduced stocks
> Lower risk of confusion
therefore fewer mistakes
in production
• Outstanding hole filling capability: The rivet
body expands radially during the setting process and
compensates hole tolerances, centering deviations
and differences in diameter, thus always building up
a playfree and tight joint.
• Safe rest mandrel locking: PolyGrip® blind rivets
neither generate rattling noises due to free moving
rest mandrels nor do they allow the risk of loss of the
rest mandrel.
• Splash waterproof are the PolyGrip® blind rivets
under certain conditions too. Hole filling and rest
mandrel locking make of them a real alternative to
closed end rivets when it is essential to prevent water
flowing through the whole joint and not only through
the rivet body.
• A large closing head: for a high tensile and
unbuttoning resistance.

What Is A Blind Rivet?
A blind rivet consists of two parts: the hollow rivet and the mandrel body. The hollow rivet has a setting head and a rivet body. The setting head is located on the processing side and is available with a range of diameters and in different forms. The head variants are as follows: dome head, countersunk and large flange. The rivet body comes in different lengths that will depend on the thickness of the material to be riveted. The job of the mandrel body is to deform the rivet body. It has a predetermined breaking point, at which the mandrel body breaks off once the rivet has been deformed sufficiently. The filling section is the portion of the mandrel body that is left behind in the hollow rivet. The spent mandrel is the portion of the mandrel body that is removed from the set rivet using the blind riveting tool and disposed of.
How To Installing?
During the setting process, the mandrel body is moved using the setting tool jaws, deforming the hollow rivet until it is firmly positioned in the component as predefined. In the end, the mandrel body breaks off at the specified point (the predetermined breaking point) and can be disposed of via the recycling system. The rest mandrel is the spent mandrel left behind in the hollow rivet and can provide an additional locking function depending on the application in question.
