When a rotating fastener is misaligned with a tapped hole, a no-start condition or cross threading can occur. The Acupoint® screw was developed by Acument® Global Technologies to overcome both of these assembly problems. As the fastener is driven, the Acupoint feature locates the tapped hole and provides proper alignment to ensure positive thread engagement.


  • Truncated spherical point
  • Point length and diameter designed to avoid thread engagement in misaligned conditions
  • Compact design reduces overall length of fastener
  • Economical design, since point is roll-formed


  • Compensates for off-angle and off-center conditions
  • Resists cross-threading and no-start conditions
  • Reduces scrap, rework and in-place costs
