When to choose TAPTITE II® screw?

TAPTITE II® thread rolling screws create a high-performance nut into steel and light alloys and offer great opportunities to reduce costs, since it eliminates the need to pre-tap and its associated cost.

TAPTITE II® screws are the solution for: 

  • Assemblies that require a low threading torque.
  • Assemblies that require pull-out and vibration loosening resistance.

How does it work?

Only 15% of all assembly costs corresponds to the screws. TAPTITE II® screws are specially designed to reduce the remaining 85%.

  • TAPTITE II® screws create a resistant and uniform thread into untapped holes with the tolerance of a machine thread.
  • During thread forming process, TRILOBULAR® design reduces friction and allows for more ergonomic assembly torque.
  • Progressive point allows for excellent axial alignment, requiring very low end load.
  • Thread forming by material lamination avoids chips creation.
  • Material displaced during threading flows to fill the space between the lobes and eliminates the tolerance between the screw and the nut member.

Benefits

  • It reduces assemblies’ overall costs. It eliminates the need to pre-tap and all the associated costs when using machine screws.
  • Thread is formed by lamination to avoid chips and ensure a high pull-out and stripping resistance.
  • Low threading torque and perfect axial alignment.
  • High prevailing torque ensures clamping and vibration loosening resistance.
  • The nut created is compatible with machine screws.

Pilot hole diameter guidelines

In order to ensure a safe installation and stable clamping force, it's relevant to pay attention to the pilot hole diameter.

The recommended dimensions for core hole diameter and length of engagement are available at Design Guidelines.
