Huck 360

The goal was simple: to design a high-strength bolting system that resists vibration loosening, no matter how extreme the environment. This system should offer quick installation and removal with conventional tools, deliver superior fatigue strength, and hold tight under high spike loads.

The result is the Huck 360 ®, the most advanced nut-and-bolt fastening system you’ll find on the market today. Easy to install, the Huck 360 fastening system is engineered to be virtually maintenance-free and resistant to vibration, even under extreme conditions.

Huck 360 stays tight under severe vibration loading by eliminating the “gap” around the crest of the bolt. When tightened, the Huck 360 fastening system fills this gap, which prevents transverse motion between the 360 nut and bolt, keeping the assembly in place.

Because the Huck 360 vibration-resistant bolt was designed with shallow, low-notch factor bolt threads (the grooves aren’t rolled as deep as a conventional bolt), the effective area of the fastener itself is widened by as much as 20%, increasing tensile and fatigue strength. In fact, the Huck 360 thread delivers 5 times the fatigue life of a standard thread bolt.

Finite Element Analysis (FEA) reveals that the shallow thread form of the Huck 360 results in 27% less axial stress in the root than conventional bolt threads. Stress concentration is the primary contributing factor leading to fatigue failures.
