5401-8 Helicoil Thread Repair Kit 1/2-13

• 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
  place.

• 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.
