Wear resistant connection (3) for joining lenghts of casing tubulars (2, 4) into assemblies referred to as strings. The wear resistant connection (3) provides a means to substantially prevent loss of material from the exterior surface of the tube wall, in the region of the connection, caused by rotating wear mechanisms present where such strings are placed in boreholes and rotated. In one embodiment, this wear resistant connection (3) provides resistance to eccentric rotating wear mechanisms arising from the bend angle either accidentally or deliberately present in casing connections.
