Blind Bolts


Arconic Fastening Systems provides a line of blind bolts that make installation a quick and simple process. These blind bolts are ideally suited for use in structures where access is limited. Their high strength and ease of use make them a great alternative to threaded systems. These fasteners are available in both unified and metric sizes.



Accu-Lok® blind bolt

The Accu-Lok® blind bolt is designed specifically for use in composite structures. It combines high joint preload with a large diameter footprint on the blind side, which provides a wider distribution of the joint preload. The large blind side upset enables the fastener to exert a very high clamping force to the structure without delaminating the composite material. The Accu-Lok® II blind bolt and Accu-Lok® IIa blind bolt are available with a non-threaded Dryv-Cap™ installation mechanism. The Dryv-Cap™ mechanism is a disposable driver that positively engages the driving recess in the fastener and eliminates the wear associated with conventional drivers.



Ergo-Tech® blind bolt

The Ergo-Tech® blind bolt is designed for both metallic and composite structures. It is available with  shear and tension, flush and protruding head styles. The corebolt breaks flush with the top of the sleeve in all grip conditions. The one-piece sleeve configuration and no threads in bearing result in superior structural integrity and high-retained clamp-up. Lightweight ergonomic tools are available to install the system. The Ergo-Tech® blind fastener is also ideal for robotic installation.



MS blind bolt

The MS blind bolt is designed for both metallic and composite structures. It is a high-strength, vibration-resistant, cost-effective blind fastener designed to meet the most challenging applications. This family of blind bolts has been used successfully in many critical areas such as engine inlets and leading edge applications.



Ti-Matic® blind bolt

The Ti-Matic® blind bolt has all of the benefits of the MS Blind Bolt with the added advantage of being lightweight due to its titanium construction. The large bulb that is formed during installation makes this fastener ideal for use in composite structures.



UAB™ blind bolt

The UAB™ blind bolt builds on the proven reliability and performance of the MS blind bolt by simplifying the installation process. One tool installs three different diameters, reducing tooling costs and facilitating robotic installation. The installed fastener provides greater spindle flushness for improved aerodynamic performance. In addition, the blind side bulb of the fastener is enhanced to provide additional grip overlap and superior performance on sloped surfaces.



Visu-Lok® blind bolt

The Visu-Lok® blind bolt is designed specifically for use in metallic structures. It provides versatility and security for numerous applications and assures the highest shear, tensile, fatigue and self-locking capabilities. When installed, it forms a solid, blind side head, with guaranteed minimum preload levels. The Visu-Lok® II fastener utilizes a disposable hex drive nut which remains on the discarded pintail following installation, and eliminates cam-out conditions for the operator. This fastener is primarily used on fixed and rotary-wing, commercial and military aircraft applications.
