POLYGRIP BLIND RIVET NUT STUDS SPLINED Splined multi-range blind rivet nut studs for improved anti-twist protection in soft materials The new GESIPA splined PolyGrip blind rivet nut studs made from M6 and M8 steel are a further development of the well-proven PolyGrip multi-range blind rivet nuts. They combine the advantages of covering large grip ranges with the knurling for increased anti-twist protection. The long longitudinal knurling ensures uniform setting characteristics over the entire grip range and a large closing head. In the ideal case, the splined PolyGrip blind rivet nut studs can replace up to 5 different standard DIN dimensions. This saves handling and storage costs while also reducing the risk of confusion in the workplace.
