China Supplier Spiral-Fluted Taps
China Supplier Spiral-Fluted Taps Description:
1. The diameter of the wire thread in the daily life is slightly larger than the diameter of the threaded hole. When the assembly is made, the wire thread is screwed through the installation of the wrench thread. The guide ring is twisted to make its diameter smaller and screw in the wire In the internal screw hole, after the installation, the wire screw sleeve produces a similar spring expansion effect, so that it firmly fixed in the screw hole, not move with the screw`s movement.
2.Increase the load capacity and fatigue strength of the threaded connection:the wire thread insert forms a flexible connection between the screw and the bottom hole of the internal thread,and this method eliminated the distance between the internal thread and the external thread and the error in half of thread angle.The load on each thread can be evenly distributed on the specified length,thus strengthening the internal thread and damping, so the fatigue strength of the threaded connection can be improved.
3.wear-resistant:the wire thread insert spiraled by the extremely hard cold rolled stainless steel wire,surface hardness can reach HRC43 ~ 50, the surface of the wire diameter (precision can be up to 2 ~ 4 m) to reduce the friction and wear,it can turn the torque decreased by 90%, which is made up by the screws friction,and with minimal tighten screw torque moment and got the biggest preload bolt tension, prevent the screw loose, make all kinds of materials and levels of screw in the best state.
4.Corrosion resistant:Because of the excellent corrosion resistance of the wire thread insert, it can ensure its practicality in the most materials and the usual environment conditions, the parts of wire screw inserts will not rust.
