  • Earth bolt :

    With its male screw whose outer thread has a polygonal
    shape, this ground bolt is used to ensure the current
    flowing and fastening performance.
  • Cambolt forming product and the method of
    producing the cambolt :

    As a component of the automotive suspension system,
    this bolt is used to connect the lower control arm to the
    main body to adjust the alignment of vehicle wheels.
  • Vision inspector of the hourglass worm gear.

  • Instrument for measuring the backlash and
    concentricity of the hourglass worm gear.

  • Bolt automatic transfer system and control
    method.

  • Apparatus for testing the performance of the
    worm gear reducer.

  • Method for manufacturing the fastener having
    a low amount of occurrence of the gray veil,
    white rust and red rust.

Licenses

  • TAPTITE® & TAPTITE 2000®

    This bolt is a high-efficiency fastener that allows for the self-thread forming for female thread​, providing an excellent
    anti-loosening performance, electrical grounding​ and significantly reduces assembly costs.​
  • MAThread®

    This functional bolt is capable of preventing any operational failure caused by cross-threading on its own. Its
    MAThread design fundamentally prevents cross threading with its P-point guide and the rounded tip of the thread.
    When fastened, this bolt prevents any fastening failure resulting from cross-threading while ensuring easier fastening.
  • TORX® & TORX Plus®

    As an improved version of a star-shaped (★) TORX, this TORX has a special structure capable of delivering a
    higher assembly torque compared to the existing products while reducing the risk of CAMOUT, in which the tool
    bits slip​ out of the recess while​ fastening. Note:​ Fastening tool bits for TORX and TORX PLUS are not interchangeable.​​
  • PT® & Delta PT® Screw

    This screw is intended for use in plastic materials only (with a threading angle of 30º) and provides excellent
    assemblability because it is designed to sit on the target object in the most efficient manner when fastened.
