PolyGrip (blind rivets)

The PolyGrip® blind rivet nuts Die PolyGrip® blind rivet nuts are the logical further development of many years of experience with our PolyGrip® multi-range blind rivets. Thanks to the benefi ts of its large drilling hole tolerance and the option of covering various grip ranges with just one fastener, the PolyGrip® blind rivet nut has become a fi rst-choice connector in many industrial applications and in trade. PolyGrip® blind rivet nuts – The GESIPA® blind rivet nuts with large grip range Bringing together multiple dimensions saves handling and storage costs while also permanently reducing the risk of confusion in the workplace and the quality problems this can result in. Large grip range: Ideally, the one PolyGrip® blind rivet nut can replace up to fi ve different dimensions of DIN standard blind rivet nuts thanks to the large grip range.

GESIPA® blind rivets are also available in colour to match the application. To guarantee the best possible durability the hollow rivets are painted using a two-component epoxy resin paint in a stow enamelling process. In addition to the visual benefi ts, the painted blind rivet also has added protection against corrosion. Aluminium blind rivets are best suited for this procedure. In the long-term they achieve the desired visual effect when joining coloured parts. GESIPA® blind rivets are available in the standard RAL colours. On request, steel blind rivets are also available in RAL colours or even special colours. Another method for colouring blind rivets and for protecting them against corrosion is to anodize them. The Eloxal method is more complex but is the most durable process for coloured blind rivets.

A closed end rivet The rivet body of the GESIPA CAP ® blind rivet is absolutely air and watertight. Liquids cannot seep through, could however seep around the set rivet, if the setting hole is too large. Therefore great care must be brought to fullfi lling the hole tolerances. The GESIPA CAP ® blind rivet – The structure For technical reasons, the rivet mandrel of the GESIPA CAP ® blind rivet must be fi xed in the rivet body. However this means that the rivet body can only deform slightly during the setting process. As a result, the cap blind rivet only has marginal hole fi lling capability. However this is necessary to be able to compensate large bore-hole tolerances. The GESIPA CAP ® blind rivet – Tight connections with care The above-mentioned technical situations make careful preparation of the application imperative. The hole diameter should be as tight as possible to ensure a fl awless function in the application for a long period.

Main features • Excellent hole fi lling capability • High clamping force • Excellent tensile strength through large closing head • Excellent shear strength through mandrel locking • Processing with standard setting tools • Process control compatible with the TAURUS® C • RoHS compliant
