A threaded joint (13) is provided with a locking mechanism for resisting loosening and over torquing. The joint has splines that are alignable with axially directed fingers (100), and shear plates (88) that are movable into the spaces between the splines (30) and fingers (100). The shear plates (88) may be supported by a shear ring (86). A lock ring (34) may be provided for maintaining the shear plates (88) between the respective spaces. Another embodiment of the joint has a knurled portion (216) that is alignable with axially directed fingers (100). The joint also includes a clamp ring (206) engageable with the fingers (100).
