TRILOBE TAPPING SCREW is an ideal forming screw to improve the reliability of screw locking operation while reducing the cost. Because the thread is triangular, when tapping, the bottom hole tapping thread does the metal forming with the vertex of triangle, meantime complete the locking operation.
In the screw locking operation, the cost of screws accounted for only about 15%, and tapping, other supporting parts and locking operation accounted for about 85%, so considering avoiding tapping, reduce the operation torque, prevent screw loose, improve the reliability of screw locking, reduce the cost and other aspects, TRILOBE TAPPING SCREW should be preferred to be chose.
Compared with metric machine screws, TRILOBE TAPPING SCREW have the advantages of: No need to tap the bottom hole in advance; No need to use anti-loose washer with strong anti-loose force, and small diameter screws can be used with good strength.
Compared with general self-tapping screws, TRILOBE TAPPING SCREW have the advantages of small locking torque, large locking torque, large holding force, good anti-loose effect, no chip powder, and small heat value of lock.
