HeliCoil Screw Thread Inserts - Features & Benefits
•Retention of Original Thread Size
HeliCoil helically wound inserts allow users to use the original size bolt or screw after repair.
•Stronger Assemblies
Tapped threads are strengthened because the inherent flexibility of HeliCoil screw thread inserts
provides a more balanced distribution of dynamic and static loads throughout the length of
thread engagement.
•No Thread Wear
Thread life is dramatically increased even after repeated assembly and disassembly, because the
hardness and smooth surface finish of HeliCoil inserts practically eliminate erosion of the thread
form due to friction.
•Corrosion Resistance
HeliCoil wire thread inserts minimise galvanic action within the threaded assembly because of
their superior corrosion resistance properties.
•Design Flexibility
Bolt tensile strength can be balanced against parent material shear strength, assuring bolt failure
rather than parent material damage.
•Eliminate Stress
Virtually no stress is introduced into the parent material because there is no staking, locking,
swaging or keying in place — the outward spring-like action of HeliCoil inserts holds them in place.
•Minimise Space & Weight
HeliCoil wire thread inserts allow use of smaller bosses, flanges and fasteners than any other
threaded insert. HeliCoil inserts can be easily incorporated into existing designs.
•Minimise Total Cost
HeliCoil inserts provide design flexibility by allowing usage of 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 HeliCoil screw thread inserts.
•Wide Temperature Range
HeliCoil stainless steel inserts can be used in temperatures ranging from–320ºF to +800ºF.
•Reduction of Costly Machine Operation Downtime
With HeliCoil inserts, quick and effective repair of screw threads is now possible and machine
downtime can be kept to a minimum.
•Quality & Reliability
Stringent quality assurance and engineering standards are rigidly enforced in all phases of the
manufacturing process of HeliCoil screw thread inserts & tools.
