Zusammenfassung:	The utility model relates to a magnetic -type screw thread sheath, include: the piece is inhaled to screw thread pillar and magnetic force. The inside of screw thread pillar sets up the through -hole, and the minimum internal diameter of through -hole is not less than the external diameter of screw thread, magnetic force is inhaled the piece cover and is established outside the screw thread pillar to with screw thread pillar fixed connection. The corrosion and the damage that arouse can effectively be avoided to this screw thread sheath in the screw thread long -term exposure air to can play lubrication action, convenient maintenance, extension screw thread class metal components's life, reduction in production cost and cost of maintenance.
