The Fixed grip lockbolt is a large diameter solution with incredible strength. It 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 fixed grip lockbolt 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 fixed grip lockbolt is the strong, reliable choice.
