HEICO-TEC® Reaction Nuts

HEICO-TEC® Reaction Nuts are the ideal complement to the HEICO-TEC® Tension Nut for use with through-bolted connections.

If you already enjoy the advantages of HEICO-TEC® Tension Nuts for active pre-tensioning, you need an equivalent reactive nut on the opposite end. Due to their special shape, HEICO-TEC® Reaction Nuts can flex elastically. And the more elastic a bolted joint is, the more durable and secure it is against untightening and loosening.

Advantages of the HEICO-TEC® Reaction Nut:
* Compatible with ISO 898-2
* Even load distribution through concave contact surface
* Preload losses are effectively reduced
* No additional space is required, tension nuts and reaction nuts have
the same dimensions
