Abstract
This tubular member thread protector generally comprises an outer member capable of rotation in a first direction about an axis and an inner member coaxially integrated within the first member and capable of rotation in an opposite direction. The inner member comprises a flexible annular sleeve having an outer surface and an interior surface defining an interior annular space capable of receiving the tubular threaded end. One or more camming surfaces are disposed about the inner sleeve outer surface. The outer member comprises a generally annular structure having a closed end, an open end, an outer surface and an inner surface. One or more raised camming members are disposed about the outer member inner surface and are aligned with sleeve camming members during rotation, the outer member camming members press against the inner sleeve camming members to radially compress the sleeve inner surface against the threaded member.
