The composite thread protectors are made of a threaded low density or  high-density polyethylene bumper, which absorbs the impact shocks and a steel shell rolled over the front edge, which insures a superior protection against hazard.

The accurate threads prevent vibrating and premature release of the protectors from the drilling during the transport. The protectors could be easily screwed and unscrewed with and simple tools, without spoil the threading.
