Eddie-Bolt® 2 Fastening System
The Eddie-Bolt® 2 fastening system provides a permanent, structural, high-performance fastening solution for varied aerospace applications. Unlike conventional threaded systems, its unique free-running Eddie-Bolt® 2 nut design greatly simplifies installation. For installation in clearance fit holes or with sealant, the Spline-Lok® recess provides a higher reaction torque than the more conventional hex recess, further simplifying installation and reducing rework while improving tool life. When a predetermined preload is reached, the lobes on the Eddie-Bolt® 2 nut are deformed into and across the flutes on the Eddie-Bolt® 2 pin, creating a positive mechanical thread lock with no frangible parts that can cause foreign object damage. The system provides superior vibration resistance and high strength levels while offering weight savings over other systems.
