The original Huck lockbolt was developed as an alternative to the conventional bolt and nut combinations, which exhibited some severe weaknesses.
These included loss of preload under service load; setting and relaxation effects in thread; self-loosening effects under vibration load; and relative movement in the
thread bearing area.
The traditional Huck lockbolt was able to combat these problems and consistently provide a secure locking system. For instance, the lockbolt has a special locking
groove design that provides vibration resistance and extreme fatigue life. This is due to a larger cross-sectional area and no stress concentration. When compared,
a 3/4 "lockbolt has 18% more bolt cross sectional area than a 3/4" standard bolt. Lockbolts also have a larger core diameter than regular bolts. Using a nut and screw
there is only 30% – 35% contact and the applications is vibration sensitive.
For more than 60 years, Huck has been bringing new and innovative joining solutions to the marketplace.
No matter what the challenge – assembly line productivity challenges, manufacturing floor safety issues, weight-related equipment performance, tough, vibration
intensive applications, or harsh environments where corrosion can erode joint integrity – Huck has the solution. Read more about how Huck takes on the tough stuff.
Huck vs. Time
These engineered fasteners are installed using a unique direct-tension/swaged-on method, providing for a smooth, jolt-free, quick and easy
installation. In fact, you can install a HuckBolt in 2 seconds or less, saving valuable assembly time while optimizing productivity. Huck helps you save time
because checking your work is quick and easy. HuckBolts were designed with a special symbol on the collar, so a quick visual inspection is all it takes to know
if it has been installed properly.
