Description.

The ELLIP-NUT™ system is the smartest solution to install a structural thread in a composite or metallic airframe element. This technology is particularly suitable where the fatigue criticality of the sub-structure does not allow holes to be drilled for the installation of conventional nut plates.

Features.

• Provides an elliptical head for torque resistance
• Large bulb for installation without damage, even on composite
• High strength self-locking thread
• Sealed version available

Tools.

Technical support and tooling solutions for elliptical countersunk preparations are provided by LISI AEROSPACE as well as hydraulic tooling to install the ELLIP-NUT™ fasteners onto the sub structure.
