HeliCoil Free Running Inserts |
|
Description:
|
HeliCoil is a Thread Insert used for creating stronger internal threads in soft metals and also for repairing damaged or stripped internal threads by regaining the original size. HeliCoil Inserts provide positive means for protecting and strengthening all tapped threads. HeliCoil protects tapped threads against wear and damage in all metals and other materials. HeliCoil Inserts develop maximum clamping load and bolt tension through efficient use of applied torque.

Features:
|
HeliCoil standard range is available in Stainless Steel AISI-304/ DTD 734, metric series ranges from M1 .6, M2 to M56 & in unified series from UNC / UNF 1-64 to 1-1/4 inch. HeliCoil Inserts are available as free running and thread locking or screw locking inserts as a standard product in both metric and inch series.
HeliCoil is also available in strip feed or reel mounted form, HeliCoil in strip feed form are best sited for significantly reducing the installation time using power tool for installation of inserts.

Specification:
|
HeliCoil Inserts or Wire Thread Inserts are made of cold rolled 18-8 grade Stainless Steel to AMS 7245 , MIL-I-8846 & DTD 734. This wire is cold rolled to a diamond cross section producing an ultimate tensile strength of approximately 1375-1725 MPa, mirror like surface finish of 2-4 Microns and flank hardness of RC 43-50 which is far in excess of the usual tapped materials and best suited for most of the industrial needs. HeliCoil Inserts can also be supplied in other materials such as SS-316, Inconel X-750, Titanium Alloys , Nimonic 90, Nitronic 60 ,Phosphorus Bronze, Beryllium Copper and with special coating and plating requirements such as Cadmium plating, Silver plating, Zinc plating , Nickel plating and dry film lubricants, Anti- Corrosion / Salt spray resistant coatings. |

Description:
|
In the free state HeliCoil Inserts are greater in diameter than the tapped hole into which they are installed. In the assembly operation the torque applied to the HeliCoil tang reduces the diameter of the leading coil and permits it to enter the tapped thread. When the torque or rotation is stopped, the HeliCoil coils expand with a spring-like action anchoring the HeliCoil insert permanently in place against the tapped hole. No staking, locking, swaging, keying, nor interference fit is required to retain HeliCoil Inserts, thereby eliminating stress concentration in the parent material. The HeliCoil Insert automatically adjusts itself, radially and axially, to any expansion or contraction of the parent material.
