Description

Everywhere, where it is required to record mobile details at extreme loadings presently, - it is impossible to do without the well-known self-stopped nuts of "Flaig+Hommel". Zapatentirovannye around the world, they are the best proof of high innovative potential of "Flaig+Hommel" today.

Lack of reliable constructive decisions for the threaded connections which are exposed to big dynamic loadings led to development of FS® - all-metal self-stopped nuts. The springing element supplied with a full round of a carving is built strongly in in the case of a nut and thus provides double fixing at the highest level.

In difference from the lock nuts existing earlier in the market, FS® - the all-metal self-stopped nut has universal application. Thanks to the patented design it meets all requirements of a safe threaded connection, it as recurrence of use, resistance to thermal loadings, protection of the interfaced carving and insignificant dispersion of the lock moment.

FS® - the all-metal self-stopped nuts are intended for repeated use without considerable loss of the lock moment which values even after the 15th navinchivaniye and screwing together considerably surpass standard indicators according to the state standard specifications P ISO standards 2320, DIN EN ISO 2320.

The Flaig+Hommel company is known as the manufacturer of FS® worldwide - the all-metal self-stopped nuts and for decades is a reliable partner of the largest world companies in various industries.


Main benefit

FS® - the all-metal self-stopped nuts provide:

- double fixing, i.e. a lock element works in the axial and radial direction

- uniform lock effect of a nut energized a preliminary inhaling at all length of a circle (360 °) the carving courses of a bolt.

The elastic element displaced on a step, supplied with a standard carving interferes with damage of the interfaced carving.

More favorable warehousing thanks to universal application.


Advantages of installation

  • The inexpensive, compact and automated installation instead of a koronchaty nut with the forelock, a glued tightening nut, a lock-nut, etc.




Technical advantages

  • The lock moment can be regulated in the narrow range of the admission depending on requirement.
  • FS® - the all-metal self-stopped nut maintains thermal loadings to 1000 °C. At a temperature above 300 °C heat resisting materials according to concrete loading are applied.
  • High durability on moving as the bearing carving rounds meet standard of DIN EN ISO 2320 is guaranteed.
  • FS® - nuts conform to requirements of standards of the Russian and foreign standards:
  • GOST P ISO 7042 DIN EN ISO 7042
    GOST P ISO 10513 DIN EN ISO 10513
    GOST P ISO 7044 DIN EN ISO 1667
    GOST P ISO 12126 DIN EN ISO 1664
    GOST P ISO 2320 DIN EN ISO 2320

DIN EN ISO 7042/DIN EN ISO 10513, DIN 6925, M and DIN DIN 980 6927/DIN EN ISO 1667/DIN EN ISO 1664 (a nut with a flange).

Production of special especially flat nuts is possible.


Benefit primeneiya

  • The best recommendations when using in the most difficult bolted connections, for example, on turbocompressors, final collectors, catalytic converters, drives with extreme loading, compressors and the vibrating details of cars.
  • Having proved in the best way for many years, the product gives opportunities of new decisions for connections of the increased complexity.
  • Thanks to the most modern technology of heat treatment higher corrosion stability is reached, than at electroplated coating, thanks to an exception of hydrogen fragility.
