HELICOIL CATALOGUE PDF

As to the Free Running version, thread by thread it is a completely free running coarse thread. To screw in the thread insert, all you need is the Smart installation mandrel of similar size as a tap. Very special is the blade position control. Simply place it and screw it in like a screw using an installation mandrel with similar dimensions to those of a tap. Existing tools from the previous model can still be used. The innovative coil of the insert allows installation from both ends with identical quality.

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 They are both available in Tanged and Tangless; Inch and Metric series. Note: Inch series Screw-Locking inserts are dyed red for identification.

Free Running Insert Screw-Locking Insert Heli-Coil inserts are precision formed coils of extremely hard, diamond shaped stainless steel. 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 Contact Heli-Coil Applications Engineering to determine the correct material for your application.

The values shown conform metric series requirement. In lieu of coatings, Heli-Coil Gall Resistant inserts are highly recommended.

Open the catalog to page 10 design data HcNCQil Assembly Strength Heli-Coil offers maximum design flexibility while adhering to conservative engineering practice allowing use of Heli-Coil inserts in virtually any application or material.

Five lengths of inserts are available. In this design manual, the lengths are listed as multiples of the nominal thread diameter of the screw; 1, VVi, 2,2-Vi, and 3. This choice of insert length balances the bolt tensile strength against the shear strength of the parent material. This allows for the design of assemblies where the bolt will fail before the parent material.

Even today, the screw is the most widely used fastening element for detachable joints. Optimised tightening methods and high-strength screws allow constant improvement. Considerably higher forces can be transmitted so that the dimension or total number of required screws can be reduced. However, only highly sustainable nut threads permit high-strength screw joints.
