Arconic Fastening Systems and Rings’ pin fastening systems product line stands as one of the most widely known and respected in the aerospace industry. We are experienced in utilizing a variety of materials including titanium, alloy steel, and corrosion-resistant steel, and to produce these parts in both unified and metric sizes. Incorporating design principles of simplicity and utility, the end user is empowered to do more with less. Arconic Fastening Systems and Rings also offers the required installation tools.
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.
Self-locking K-Fast™ nuts
are designed for use on Hi-Lok®, Hi-Tigue®, Veri-Lite®, and Aero-Lite® pins. Tools, also available from Arconic Fastening Systems and Rings, feature precise preload control for automatic installation and help provide the airframe industry with high-speed efficiency and cost effectiveness in production. The low-profile K-Fast™ nut allows for easy installation in limited access areas.
Aero-Lite® pin and Veri-Lite® fastening system
Our unique design of the threads on the Aero-Lite® pin
and Veri-Lite® fastening system
allow the overall length of the pin to be reduced while maintaining the same grip capability and strength level as those of the Hi-Lok® system it is based on. This enhancement reduces the weight of these systems by as much as 15% for applications where weight is critical.
Hi-Lok® two-part frangible fastener
Our Hi-Lok® two-part fastening system
delivers high-fatigue resistance without sacrificing strength in an efficient, dependable, all-purpose fastening system. Installation in difficult access conditions is no problem with Hi-Lok® and a wide range of sizes and material combinations make it a versatile solution for many assembly problems.
Hi-Tigue® pin fastener
In situations where a controlled interference fit is needed, Hi-Tigue® fasteners
offer all of the benefits of the Hi-Lok® fastening system along with a unique bead design that enhances the fatigue performance of the structure.
