New High Strength in Steel: G-Bulb Structural Blind Rivets GESIPA has developed a new range of high strength structural blind rivets called G-Bulb with diameters of 4,8 and 6.4mm, to fit grip ranges from 1.5 up to 8.0 and 10.5mm. The G-Bulb rivet features a wide grip range, together with high shear and tensile strengths generated by the rivet function and the mechanical lock of the rest mandrel in the eyelet. In combination with the patented function crimping on the rivet body the G-Bulb provides tight and sealed joints in a large variation of hole sizes. The G-Bulb rivet generates a large closing head which transfers high strain and clamping load to the application. With a mandrel breakload of 14kN, the G-Bulb rivets can be installed with standard tooling.
Main Features
- Excellent hole filling capability - Highest clamp force - Highest tensile through large closing head - Highest shear through rest mandrel locking - Setting with standard tooling - Process control compatible with Taurus C - Fully ROHS compliant
