Eddie-Bolt® 2 Fastening System
Our Eddie-Bolt® 2 fastener is a high-performance aerospace fastening system that’s ideal for aerospace composite structures. It’s state-of-the-art, free-running nut provides exceptional clamping power.
The Eddie-Bolt® 2 pin is designed with five flutes in the upper portion of the threaded area. This feature allows a positive mechanical lock to be made during installation by using the free-running Eddie-Bolt® 2 nut™. Eddie-Bolt® pins and nuts are available in various diameters, materials and finishes. The free-running nut and superior mechanical lock provide many significant benefits as well. During installation, the Delta-Rad™ driver fits over the three external lobes of the Eddie-Bolt® 2 nut. Torque is applied, and upon reaching the required clamp load, the lobes automatically deform into the flutes of the Eddie-Bolt® 2 pin. As a result, they form a positive mechanical lock and complete the installation without any foreign object debris (FOD).
The free-running nut simplifies and speeds installation by allowing the nut to be installed up to the sheet line with no prevailing torque.
The potential for galling at high installation speeds is eliminated because of minimal friction between the pin and nut. In addition, the new Spline-Lok® recess option provides increased torque-reaction capability, substantially reducing tool wear and breakage.
Enhanced limited access capability:
The Eddie-Bolt® 2 fastener can be used where other systems cannot because it has a lower profile pin and nut, allowing for easy installation and making limited access tooling possible.
High vibration resistance:
The true mechanical lock provides significantly superior vibration resistance compared to other fastening systems that rely on friction locks.
Enhanced joint performance:
Its high, consistent clamp-up provides superb static and fatigue strengths.
The FOD associated with frangible collars is eliminated.
The Eddie-Bolt® 2 system eliminates the need for torque-controlled tooling, reducing manufacturing costs and enhancing reliability.
