​​​​​​High Performance Anti-Loosening Bolt

  • Achieve powerful anti-loosening performance by applying normal tightening
  • Accomplish downsizing with enhanced axial force and increased fatigue strength
  • Dramatically cut costs through a streamlined design without the need for additional loosening prevention measures
Our team of experts is ready to support you.


  1. Contact with internal screw occurs gradually from thread top of external screw.
  2. Axis is raised toward seat surface side (upward) as tightening torque is applied.
  3. External screw and internal screw contact each other at flat surfaces.
  4. Repulsive forces act on seat surface and thread surfaces, thereby generating high anti-loosening force.
