They just confer with the dimensions on the threads relative into the screw diameter.
Screw thread, employed to transform torque into the linear power within the flood gate. The operator rotates the smaller vertical bevel equipment in the center. Via mechanical edge this results in the horizontal bevel gears (at much still left and far suitable, with threaded Centre holes) to rotate. Their rotation raises or lowers the two lengthy vertical threaded shafts - as they are not free of charge to rotate.
