This is true.

A banjo bolt with a different pitch wont screw in too far, maybe one thread before it stops....where as the correct pitch bolt will screw in very easily.

The VF series banjo is the same as TD04 though, so no problems there..

MY FP TD06 had a different pitch banjo fitting to the VF series, and I ended up buying a 13 dollar Earls banjo bolt in the correct pitch....BLING BLING
