Products
inserts are precision formed screw thread coils of
stainless steel wire having a diamond shape cross section.
Heli-Coil precision formed wire inserts are readily
recognized and highly regarded products in the industry.
Since its inception in 1938, Heli-Coil has been identified
as an industry leader offering products with superior
performance, reliability and integrity.
Helicoil inserts are used into softer metallic or non
metallic materials to give them steel-like thread
performance. This has enabled industries to use lighter
weight materials such as aluminum, FRP, Nylon etc without
having to give up thread strength of their fasteners.
Heli-Coil strict quality programs ensure to meet the
latest industry standards of QS,ISO,TS and AS
specifications, as is evident in Heli-Coil track record of
consistently passing audits without technical findings.
Heli-Coil SPC and detailed inspection programs elevate the

Helicoil Primer-Free tangles inserts are designed for use
in applications where galvanic corrosion between
dissimilar metals is a concern. Coating not only protects
the base material and provides excellent lubricity, but
more importantly, eliminates the need for liquid chromate
primers. With Primer-Free coated inserts, the inserts are
always evenly coated, providing more accurate bolt
torques.
Spiralock inserts are made of cold-rolled Type 304
stainless steel wire (AS7245), work-hardened to a tensile
strength above 200,000 psi, having a hardness of Rc43-50.
The finished surface (8-16 micro inches) is exceedingly
smooth, virtually eliminating friction-induced thread
erosion.
It is important to select the proper insert length in
order to balance the bolt tensile strength against the
shear strength of the parent material. The insert lengths
are calculated numbers because the inserts cannot be
measured in the free state. The lengths are multiples of
the nominal thread size, or diameter, of the insert.
Please see Table III for insert dimensions. Using the
insert length selection table below, an insert length can
be selected which will produce a thread system strong
enough to fracture a bolt before it will strip or damage
either the parent material or the insert.
Spiralock wire thread inserts are helically coiled
fastening devices that provide permanent, wear-resistant
screw threads that exceed the strength of most parent
material; the inserts are designed to protect tapped holes
against failures due to stripping, seizing, corrosion, and
wear. Spiralock inserts are unlike any other wire thread
insert due to the fact that our inner diameter wire
geometry incorporates our 30° wedge ramp thread form
design. Our wire thread inserts are available in two
styles: tanged and Drive Notch, engineered with no
tang.
Crest of bolt seats against ramp of Spiralock insert
thread profile, preventing transverse movement of bolt
relative to insert, thus resisting loosening due to
vibration. Spiralock insert meets or exceeds the
applicable parts of NASM8846; e.g., the wire tensile
strength, chemical composition, and methods of
inspection.
Spiralock insert is not a prevailing torque-type
screw-locking insert—no risk of galling or seizing of bolt
and insert Similar to NASM1130 inserts Provides proven
superior vibration resistance to standard locking
inserts.

installed insert, grabs the removal notch and threads the
insert out without damaging the internal STI threads or
surface of the casting. Helicoil Tangless removal tool has
ability to back out or adjust an insert that has been
installed too deep; giving operators greater control over
installation depth.
HeliCoil Threading Taps are available in HSS material as
standard product and as specials in HSSE or HSS with High
Cobalt contents. In addition the taps can also be provided
with special wear resistant coatings.
Standard HeliCoil taps are designed and manufactured of
high speed steel to the most rigid specifications in
various types and styles to produce holes for tolerance
class 4H5H and 5H6H in Metric series and of class 2B/3B in
UNC/UNF series for use in the general range of aluminums,
magnesiums, mild steels and alloy steels.
Types of HeliCoil taps:
HeliCoil Gauges are available as Go/No Go thread plug
gauges for inspection of tapped holes prior to HeliCoil
fitment. The gauges are available in 5H & 6H class for
Metric sizes and 2B/3B for UNC/UNF sizes.
Accuracy of the finished thread when the insert is
installed is dependent upon the accuracy of the tapped
hole. If the finished tapped hole gages satisfactorily,
the installed insert will be within the thread tolerance.
It is not necessary to gage the installed insert. After
the insert is installed, the GO thread plug gage may not
enter freely; however, the insert will always seat itself
when the bolt or screw is installed and tightened.
(Reference NASM33537).
Gage handles and all gage nibs are marked with the extreme
product limits for the particular size and class of fit.
When gaging tapped holes which have been thoroughly
cleaned or which have a protective finish applied, the
gage should always be lubricated with light oil. HI nib
may enter provided a definite drag results on or before
3rd turn from entry – Ref. FEDSTD-H28, Screw thread
Standards for Federal Services.
Working gages provide a guaranteed minimum wear allowance
on the pitch diameter of the GO members of two ten
thousandths of an inch (.0002). These gages are
recommended for production in sizes 1/2 inch and
smaller.
Reference gages have pitch diameters on or close to
minimum (basic size). They are essentially laboratory or
master gages and should be used in case of conflict
between two working gages. Conflict can occur when one of
the gages has experienced more use and wear.
The complete gage consists of the GO thread plug gage, the
HI thread plug gage and the appropriately marked gage
handle. Accuracy of the finished thread, when the insert
is installed, is dependent upon the accuracy of the tapped
hole.
