Discuss your requirements with our dedicated systems team to find the optimum solution to suit your need. To install BobTail the basic tooling requirement is: H Installation Tool – Either pneumatic or hydraulic Nose Assembly – To match with the fastener and tool Powerig® – To supply power to hydraulic tools Additional Hose Set – Sometimes...

HOW IT WORKS How BobTail Works Installation Sequence Clamp Force or Pre–Load: In the initial stages of the installation process, the tool engages and pulls on the tail of the fastener. The joint is pulled together before the anvil portion of the nose assembly is forced down the collar. This progressively locks (swages) it into the grooves of the harder pin. The pin and swaged collar combine to form the installed fastener. The squeezing action reduces the diameter of the collar, increasing its length. This in turn stretches the pin, generating a clamp force over the joint. Shear strength of BobTail...
