Clamps are an integral part of the coupling and cannot be removed. All screws are hex socket, steel with black oxide finish. For stainless steel screws. Screw torques are the screw manufacturer’s maximum ratings. Coupling material is 2024-T3.51. QQA225/6 aluminum with MIL-A8625 Type II black anodize. Static torque is the maximum coupling torque rating. Torque and torsional stiffness rating are at a maximum misalignment, not in a straight line. The expanding shaft torque holding force is dependent on the pilot hole finish and the expander screw’s tightness. Mass and inertia are calculated without the G10 insert. E & F have thru bores only.
