The construction of the Joint revolves around a 3/8 x 14 stainless steel joint pin. It is set into a black fiber nylon insert and secured by a polished chrome or black implex joint collar depending on model. It would then screw into a corresponding black fiber nylon insert in the shaft also secured by a polished chrome or black implex joint collar depending on model.
Since the original concept of Cuetec was a cue with a coating of fiberglass or graphite the big question was how to prevent moisture from penetrating into the wood causing expansion and the inevitable splitting of the composite coating. The answer was to seal the ends of the cue so moisture could not penetrate to the wood core by using a fiber nylon insert around both ends of the joint.
As it turns out, one of the by-products of this joint construction was excellent transfer of energy from the shaft through the rest of the cue. Low levels of vibration and deflection were a direct result of this efficient transfer of energy allowing for better shot control
When it came to the professional wood R360 series, the need for this type of joint became more of the quality hit and play rather than the original purpose of sealing moisture out of the cue since the R360 is not composite clad.
