The C50L has defined HuckBolt for more than 50 years.

The Huck C50L offers superior vibration resistance and overall durability for heavy-duty fastening jobs and is ideal for use within applications where consistent, uniform high clamp force is required.  Testing has proven that C50L fasteners meet, or exceed the performance or torqued bolts in both shear and tensile strength, as well as fatigue life. For applications ranging from railcar to mining equipment manufacturing, the C50L is the strong, reliable choice. Huck BobTail® provides the next-generation alternative to C50L.
