Description:
 Thread Rolling into self Tapping screw (Thread Rolling Tapping Screws) - triangular tooth self Tapping screw is also known as Type (TT Type Tai is still has a patent system developed based on the principle of forming tap Thread Rolling into a self Tapping screw with special design of screw Thread and end the can in the intermittent, , under pressure to roll into a fit of the female thread at the same time around the hole of the material can be more easily fill tapping screw thread and the bottom of the tooth space, due to its thread forming self tapping screw friction force is small, so you can use on the thicker material of rotation required torque control better, and after the combination intensity of higher screw thread rolling into a self tapping screw its engineering standard definition than molding or cutting self-tapping screws in the material, heat treatment, on the strength of the definition of a higher and more clear, make the screw/roll into a self tapping screw become real "structure with" fasteners
