Industrial Distribution Group C6L ® The original vibration-resistant HuckBolt ® Locking groove design Simple installation Consistent clamp force 3/16"-3/8" The Huck C6L ® The classic 6-groove locking fastener built with staying power. A result of Huck International innovation a half-century ago, the versatile Alcoa Fastening Systems & Rings C6L® HuckBolt® remains the number one fastening system for applications that require a strong, vibration-resistant seal today. C6L’s exclusive locking groove design ensures a permanent fit that resists loosening. That means it’s ideal for applications from general manufacturing to such high-vibration applications as HVAC, trailer and container assembly, rotary and rotating equipment, shopping carts, railroad and transit cars, geodesic structures, and many others. In addition to offering superior fastening performance, the C6L system reduces labor and installation costs, along with rework and warranty expenses. For example, using the C6L eliminates the need to hire certified welders or specially trained employees, because workers can be instructed to install these foolproof fasteners in a matter of minutes. The C6L is simply stronger, easier to install, and more durable than welding, adhesives, or conventional threaded fastening systems. 2 Installation Sequence The C6L’s unique design virtually eliminates installation errors caused by operator or tool variables. The C6L ensures that once the collar swage is complete, the pintail breaks off and the fastener is tightly installed. No rework required. And you can count on consistent, high-uniform clamp force with every C6L installation, time after time. 1 The pin is inserted into the prepared hole and the smooth bore collar is placed on the pin. 2 The installation tool is applied to the pintail. When the tool is activated, the jaws in the nose assembly pull on the pintail and the nose anvil pushes on the collar to remove any gap. 3 4 The nose anvil starts to swage the collar into the lockgrooves on the pin. Continued swaging causes the collar to lengthen and develop clamp. When swaging of the collar into the lockgrooves is complete, the pintail separates from the pin which completes the installation cycle.
