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:
◾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
Compatible with ISO 898-2
HEICO-TEC® Reaction Nuts meet all requirements of ISO 898-2. They therefore have the same strength as conventional hex nuts and can replace them 1:1. However, they must not be used for active pre-tensioning, rather only on the opposite reactive end.
