    Helicoil Thread Repair Kit

    • Heli-Coil inserts are available in thread repair kits and sets for repairing tapped holes which have been stripped or damaged due to wear, corrosion and over-torque. They are available in inch, metric, spark plug and pipe thread series.
    • All kits have a quantity of inserts, the proper size drill, high speed steel Heli-Coil tap and an installation tool. Also included in smaller size kits a tang removal tool and quantities of three lengths of inserts.


    Heli-coil Inserts provide a
    positive means for protecting and
    strengthening tapped threads in any
    material. The unique design features
    of the insert offer many benefits.

    • Stronger Assemblies
      Tapped threads are strengthened
      because the inherent flexibility
      of the insert provides a more
      balanced distribution of dynamic
      and static loads throughout the
      length of thread engagement.
      This flexibility also compensates
      for variation in lead and angle
      error allowing each coil to carry
      its share of the load.
    • No Thread Wear
      Thread life is dramatically
      increased even after repeated
      assembly and disassembly
      because the insert hardness
      and surface finish practically
      eliminate erosion of the
      thread form due to friction
    • Corrosion Resistance
      Under normal environmental
      conditions, Heli-Coil inserts
      minimize galvanic action
      within the threaded assembly
      because of their superior
      corrosion resistance.
    • Design Flexibility
      Bolt tensile strength can be
      balanced against parent material
      shear strength, assuring bolt
      failure rather than parent
      material damage. Five insert
      lengths are available in each
      thread size.
    • Eliminate Stress
      Virtually no stress is introduced
      into the parent material
      because there is no staking,
      locking, swaging or keying inplace – the outward spring-like
      action of the insert holds it in
    • Minimize Space & Weight
      Heli-Coil inserts allow use of
      smaller bosses, flanges and
      fasteners than any other insert.
      Heli-Coil inserts can generally
      be incorporated in existing
      designs, where no provision
      has been made for an insert,
      without increasing boss size.
    • Minimize Total Cost
      Cost savings abound. Lower
      insert cost, lower installation
      cost and Heli-Coil inserts
      provide design flexibility by
      allowing a wide choice of
      parent materials while
      maintaining maximum
      threaded assembly strength.
    • True Clamping Torque
      Maximum clamping action and
      bolt tension are assured with
      minimum wrench torque because
      of the mirror-smooth surface
      finish of Heli-Coil inserts.
    • Wide Temperature Range
      Heli-Coil stainless steel inserts
      can be used in temperatures
      ranging from –320°F to +800°F.
    • Quality & Reliability
      Stringent Quality Assurance
      and Engineering Standards are
      rigidly enforced in all phases of
      the manufacturing process.
      This assures integrity of your
      product design.
