Screw -Lock Inserts

We have expertise in manufacturing and supplying an extensive range of Screw – Lock Inserts. These inserts have a polygonal central coil, which assists in exerting a prevailing and resilient torque on the bolt. This ensures to prevent the bolts or screw from loosening under vibrations and extreme impacts. These bolts and screws can be fitted and removed several times as per the requirement without any considerable loss of torque. Further, when these Screw-lock inserts are fitted into nuts provide what is probably the best kind of self-locking nuts, known as nuts.

HELI-FORM Screw-Lock Thread Inserts

HELI-FORM Screw-Lock Thread Inserts

HELI-FORM Screw - Lock Thread Inserts offer all the above benefits as Standard Thread Inserts.

In addition HELI-FORM Screw - Lock Thread Inserts provide :-

a) Positive self locking torque.

b) A resilient locking mechanism that grips the bo;t and prevents it from loosening during vibration or impact.

c) Repeated assembly and disassembly without appreciable loss of self locking torque.

d) Saves space, weight and money by eleminating lock wiring, lock nuts,lock washers, chemical compounds and other locking mechanism.


HELI-FORM Screw-Lock Inserts Locking Principle

The locking action is achieved by one or more coil having a series of straight segments or 'CHORDS' called the GRIP coils. When the bolt enters the grip coil these segments flex outward, exerting a pressure between the flanks of the bolt thread to establish an extensive contact area which provides a positive and consistant self locking torque for more cycles than any other torque mechanism.
