Designed to overcome inherent weaknesses with standard lockbolts, the BobTail has no pin-tail and as a result of this zero pin-break, no waste material to collect and dispose of or potential corrosion issues post installation. The lightweight, low-noise, low-maintenance tooling, which can be used for both installing and removing fasteners, provides a smooth, shock-free, speedy installation sequence i.e. two seconds for a 16mm diameter fastener - twice as fast as any other large diameter lockbolt on the market. As a result, no torque or impact is transferred to the operator.
BobTail fasteners install in only 2 seconds, up to twice as fast as any other large diameter LockBolt on the market*.
BobTail thread form is shallower than a common bolt thread, so there is a larger cross-sectional area to spread out the service load, and fatigue strength increases.
The thread form also has a much larger root radius than a common bolt thread, so stress concentration at the thread root is also reduced, which increases fatigue strength even more.
