The nut design is a key factor to achieve the highest precision of a collet

  • A 45° trapezoidal thread offers less friction between alignment to the center when clamping a collet

  • Since the threads greatly influence accuracy, they are finished after heat treatment. Therefore, bad influence from clamping action is eliminated, which enhances clamping performance.
  • The nut incorporates a thrust bearing with steel balls that prevent stress to the collet and allows a smooth clamping force.
