Product Name:
|
Screw Locking Inserts |
|
Description:
|
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. |
|
Features:
|
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 MIL-I-8846 & 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. |

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.
