Thread insert Advantages and representation
Type locking screw sheath is also called the self-locking type screw sheath, type locking screw sheath is made of ordinary steel wire thread sheath evolved from a kind of fastener products, is in the midst of flexible screw sheath increased once or several times made from poly thread sheath called type locking screw sheath.Type locking screw sheath after screwing in the screw hole, in addition to rely on their own elastic should be fixed to the screw hole, also using the polygon edges and the friction between the screw thread matching to screw up the locking function.When the screw into the hole type locking screw sheath.Screw before enter the polygon clamp ring is loose, screw through the locking ring will open the side of the polygon when make the bending deformation of the side of the polygon, which hold the friction screw, screw, the friction force makes the screw will not automatically loosening due to vibration of, don't need to take other measures for locking.
