All HeliCoil Thread Repair Kits including the Professional Thread Repair Kits are used for creating stronger internal threads in all metals, composites, polymers and other materials by repairing damaged or stripped internal threads and regaining the original thread size. HeliCoil Thread Repair Kit creates longer lasting durable threads, avoids thread over-sizing, increases the possibility of higher torque application in weaker metals, significantly reduces the bolt breaking problems & HeliCoil being made of stainless steel protects against atmospheric corrosion. HeliCoil Professional Thread Repair Kits include everything required to do the job right & good number of inserts each of 3 lengths (short, medium & long) for multiple applications, HSS drill bit ,Finishing tap, installation tool and tang breaking tool & all in a rugged new box. These kits are available in metric range from M2 to M12 and in UNC/UNF range
 
     

 
   
HeliCoil standard range is available in Stainless Steel AISI-304/ DTD734, metric series ranges from M1.6, M2 to M56 & in unified series from UNC / UNF 1-64 to 1-1/2 inch. HeliCoil is also available in strip feed or reel mounted form, HeliCoil in strip feed form are best suited for significantly reducing the installation time using power tool for installation of inserts.
HeliCoil Inserts or Wire Thread Inserts are made of cold rolled 18-8 grade Stainless Steel to AS7245 , MIL-I-8846 & DTD734 specifications. 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.
   
 

 
 
HeliCoil Screw Locking Insert as standard is available in Stainless Steel AISI-304/ DTD 734 . Metric series ranges from M2 to M39 & unified series from UNC / UNF 1-64 to 1-1/2 inch. HeliCoil Screw Lock Insert is also available in strip feed or reel mounted form .
HeliCoil Locking Insert provides an exclusive, resilient internal locking thread that grips the bolt and prevents it from loosening under vibration or impact. One or more coils of the HeliCoil insert, having a series of straight segments/ chords, achieve locking action. HeliCoil Locking Insert permits repeated assembly and disassembly and will not relax their grip on the screw even in tough metals such as cast iron, alloy steel, titanium, etc. HeliCoil Locking Insert positively secures threaded members against loosening caused by vibration and shock. HeliCoil Locking Insert has a high reusable factor permitting frequent removal and reassembly of bolt without appreciable loss of torque. It has positive self-locking torque, complying with NASM8846, MA1565 and MIL-N-25027. It eliminates the usage of lock wiring, lock nuts, lock washers, chemical compounds, plastic pellets/ patches and other locking mechanisms. The HeliCoil Locking Inserts are subjected to extensive tests in tension, torque, shear, vibration and fatigue, conducted by the American & European companies. Its applications include sectors like Aviation & Aerospace, Electronics, Industrial, Automotive and Military.
 
     
 
     
The self-tapping threaded inserts are a single ended cylindrical metal bushings with an internal and external thread and are specially designed to cut their own threads as they are being driven into a drilled hole. These inserts are produced in standard and thin wall configurations with either a single slot or multiple holes providing the thread cutting features. These are suitable for installation into a range of metals and non-metals. The inserts are generally available in case hardened steel, austentic or ferritic stainless steels, special alloyed steels with a finish type yellow chromated, zinc and passivated types as standard parts and other coatings and platings are available upon request.
Self Tapping Insert Thread Standards

Metric

Description:

Self-thread tapping / thread cutting action in drilled holes.

Application:

This is a self-tapping insert for the creation of wear-free, vibration resistant screw joints with high load capacity in materials which are having low shearing strength.

Special Feature:

The thread cutting action is performed by the cutting slots on the Inset Self Tapping Insert. By tapping its own thread, the Inset Self Tapping Insert eliminates the need for pre-taped holes.

Size Range:

Internal Thread M2 to M30 and UNC /UNF 4-40 up to 5/8 inch
