New Huck-brand BOBTAIL lockbolt fastening system offers increased vibration resistance and fatigue
Comprised of Huck’s BOBTAIL lockbolt and its lightweight installation tooling, the fastening system provides very high vibration resistance and fatigue strength. Utilizing a swaging process, the BOBTAIL’s collar is pressed onto the hardened threads of the lockbolt is forced into the grooves of the pin — forming a permanent, vibration-proof connection. “Unlike conventional threaded fasteners, this technique ensures full metal-to-metal contact between the collar and the lockbolt, providing vibration resistance even in the most severe environments,” it’s reported.
With BOBTAIL’s shallow thread and large root radius, it offers 5 to 10 times the fatigue strength of conventional nuts and bolts. Its fastening system is offered in Grades 2, 5, and 8 and comes in a variety of standard and metric sizes.
