The thread conditioning device is for rotational movement about a threaded bolt to remove corrosion and debris and to otherwise condition the bolt threads for further use. The device or chaser includes a body having an opened and generally C-shaped configuration when viewed cross sectionally to its axis of rotation. The body of the device includes an interior threaded surface to engage the threads of the bolt to be conditioned, an exterior surface to mechanically engage, grasp and rotate the device, and two generally opposing end surfaces. The open portion of the C-shaped body is defined by two lateral surfaces which extend between the opposing end surfaces from the interior surface to the exterior surface of the device. The two lateral surfaces preferably form positive, acute angles relative to the interior surface of the body when viewed cross sectionally. The intersections of the lateral surfaces and the interior threaded surface form two generally spacially opposing plowing edges of the device. The body is of a deformable and resilient construction to allow the plowing edges to be brought in closer proximity when mechanical forces are applied to the exterior surface of the device. The rotational movement of the device about a threaded bolt allows the plowing edges to condition the bolt threads, allows the resultant debris to egress thru the open portion of the body, which, additionally, allows controlled plowing action forces to be applied on the plowing edges by the user of the device.
