Abstract
A thread protector consists at least in part of shock-absorbing elastic material and has a complementary thread of which the root and/or flank face exhibits projections. A sealing face of the thread protector can also be provided with projections running around it. In this way easy screwing-on and/or centering of the thread protector is achieved, with better automatic locking against unintentional loosening of the thread protector, and non-uniform displacement of thread grease is avoided.
