TAPTITE II® trilobular screws with hexagonal head and TORX recess.


Product overview
TAPTITE II® thread rolling screws create a high performance nut into steel and light alloys and offer great opportunities for cost reduction as it eliminates the need of pre-tap and all associated cost. Only 15% of all assembly costs corresponds to the screw. TAPTITE II® screws are specially design to reduce the remaining 85%. Apart from the references available in stock, we produce customised screws to fit your exact requirements. To improve their functionality, TAPTITE II® screws can be produced under different head styles, recess, dimensions and coating configuration.

Further specifications
Key features:
- TAPTITE II® screws are the solution to applications on steel that require a low threading torque and assemblies that require pull-out and vibration loosening resistance.
- In-place fastening cost reduction by eliminating the need for additional locking elements
- Eliminates the need of pre-tap and all associated costs when using machine screws
- Forming thread by lamination avoids chips creation and ensures a high pull-out and stripping resistance
- The perfect axial alignment of the screw in the base implies a minimum effort to start the threading and reduces the torque
- High tightening torque that maintains compression of the joint
