Abstract: A device for protecting external threads on the pin or male end of a tubular member such as drill pipe, tubing, casing, and the like (collectively referred to hereinafter as "pipe"). The thread protector includes a cylindrical inner sleeve including a cylindrical rigid member enclosed on one end by an overlapping end wall and open at the other end thereof, and further including a cylindrical expansible member in intimate contact with the exterior cylindrical surface of the rigid member. A cylindrical thread shield member is disposed concentrically around and outwardly spaced from the inner sleeve such that an annulus is formed to receive the threaded segment of the pipe.
