  Acupoint®

Overview

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.

Features

  • 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

Benefits

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

Design Guidelines

  • Sizes: M2.5 thru M12 #2, #5, #10, 1/4"
  • Thread Design: Machine screw; others as specified
  • Head Design: Can be used with all external head designs; also available in studs
  • Drive System: Can be used with all fastener drive systems, including TORX PLUS® Drive
