Huckbolts C6L Series

The classic 6-groove locking fastener built with staying power.

C120L® - 8.8-grade two-piece lockbolt fastener

A result of Huck International innovation a half-century ago, the versatile Alcoa Fastening Systems C6L®/C120L Huck LockBolt remains the number one fastening system for applications that require a strong, vibration-resistant seal today.

Huck C6L/C120L’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, railroads, and transit cars, geodesic structures, and many others.

In addition to offering superior fastening performance, the Huck C6L/C120L system reduces labor and installation costs, along with rework and warranty expenses. For example, using the C6L/C120L 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 Huck C6L/C120L is simply stronger, easier to install, and more durable than welding, adhesives, or conventional threaded fastening systems.

Huck LockBolts designed for consistent installation, easy inspection.
The C6L/C120L’s unique design virtually eliminates installation errors caused by operator or tool variables. The C6L/C120L 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/C120L installation, time after time.

A quick visual inspection, along with an occasional dimensional check, is all that’s required to make sure the C6L/C120L is installed accurately.

Strong support.
Alcoa Fastening Systems’ skilled and knowledgeable technicians – your Huck System Specialists – are ready and waiting with valuable consultation, evaluation, installation assistance, and in-depth staff training capabilities. No other fastening company can match this level of premium, value-added support.
