Lockbolts, Structural Blind Fasterners and Tooling

When High Performance and Holding Power are Critical Huck Structural Blind Rivets are Howmet’s answer to loosening and vibration challenges. And it’s the reason they are the world’s strongest, most reliable, most consistent blind fastening solution available. In fatigue tests, Huck Structural Blind Rivets outlast alternative forms of fastening. Engineered with a unique locking design, many of these fasteners create an internal lock during installation that virtually eliminates pin push-out by mechanically locking the pin to the sleeve. Each locks permanently into place with little effort. Simple, visual inspections ensure joint integrity. In applications where vibration resistance, reliability, and strong hold are critical, no fastening system is more dependable than Huck. HuckLok’s proprietary solid circle lock ensures maximum strength and vibration resistance. Shear ring at the sheet line provides a consistent clamp. Huck ® Structural Blind Rivets Auto-Bulb ® Bulb forms directly on sheet line. The Competition Bulb forms irregularly above sheet line resulting in lower installed values. Even in minimum-grip applications, Huck fasteners outperform the competition. They’re engineered to form a bulb directly on the sheet line, precisely where it’s needed, to prevent pull-through.
