Heli-Coil Inserts have evolved since their inception in the 1930’s and now
include the complete range of both tanged and tangless free running and
screw-locking wire insert systems.
Today Heli-Coil delivers a vast array of high quality inserts and installation tools designed to meet
the needs of the industry’s ever demanding designers and manufacturers. Inserts are available in
a variety of materials and special coatings. With Heli-Coil threads, tapped holes are strengthened
and thread life is dramatically increased.
Heli-Coil Inserts are The Original.
Manual Tools
Heli-Coil offers a complete line of tooling together with a
full array of STI taps, gages and tang break-off tools.
For production runs, prototype work, salvage and repair, Heli-Coil offers a range
of installation and extraction tools for both tanged and tangless inserts to
complete the needs of your application.
Power Tools
For higher volume production, we offer both electronic and
pneumatic power inserting tools.
Heli-Coil power tools can be adapted to assembly stations, rotary tables and
transfer lines for rapid installation. Our application engineers are always
available to assist in installation techniques and special tooling.
Quality
Our strict quality programs ensure that we meet the latest
industry standards of ISO/TS 16949:2002, ISO 14001:2004,
AS/EN/JISQ9100 Rev C and ISO 9001:2008. A comprehensive
Business Management System elevates our quality levels well
above our competitors.
Features & Benefits
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 frictional wear.
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 in place – the outward spring-like action of the insert holds it in place.
Minimize Space & Weight
Heli-Coil inserts allow the use of smaller bosses and flanges than any other insert.
Heli-Coil inserts can generally be incorporated into existing designs, where no other 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.
High Volume Production
Heli-Coil inserts are available mounted
on plastic strips and wound onto reels
(500 or 1000 inserts per reel). With power
installation tooling, use of strip feed inserts
will substantially increase installation rates
by minimizing handling.
Universal Acceptance
Heli-Coil Standard and Screw-Locking Inserts are the original – and have an extensive background of tension, torque, shear,
vibration and fatigue tests conducted by American industry’s leading companies as well as the U.S. Military. Successful
applications in the fields of aviation, electronics, industrial, automotive and military equipment provide a wealth
of experience and confidence in the performance and reliability of Heli-Coil inserts.
Custom Design Services
In addition to the benefits listed above,
Heli-Coil provides a wide range of support
to solve fastening problems. This design
catalog is one of them. The following pages
are presented in a manner to make it easy
to “design-in” Heli-Coil inserts to take
advantage of the extraordinary benefits
they provide.
Additionally, our Sales Engineers,
Applications Engineers and Design
Engineers are available for consultation
for specific designs. When the product gets
to the manufacturing phase, our extensive
experience in production tooling and
installation techniques ensures that you
can indeed make your product better
with Heli-Coil inserts.
