Abstract
A winder for a threaded connection of two axially aligned bodies where a first body comprises a male portion at an end connection portion and a second body has a female portion at an end connection portion. The female portion comprises a sleeve with a threaded portion on an internal face. The winder includes a winder ring encircling the male portion. The winder ring forms an internal surface and an external surface having a threaded portion. The internal surface of the winder ring includes a number of parallel grooves that are perpendicular to a rotational axis of the winder ring. A further male portion comprises external, circular grooves complementary to internal, circular ridges of the winder, and a threaded connection between two axially aligned bodies where the connection comprises the winder and the male portion.
