The Benefits of Huck Bolts

Huck Bolts - They Last Forever

What is a Huck bolt? Understanding Huck bolts and their benefits. 

Huck bolts are fundamentally a two-piece grooved pin and a collar combo where the collar sits over the pin and is compressed together via a designated tool. The tool presses the collar into the pin's grooves making the two-piece combo an integrated one-piece entity. See How Huck works here. 

Huck Bolts are designed to provide a permanent, vibration-resistant solution for numerous applications. Their high strength means they are well suited to applications where the joint is important to the success of the structure. They assist in lowering production costs by faster installations, whilst being a clean and safe alternative to welding and a better more permanent option than a standard bolt and nut combo.

The Huck bolt was developed to solve the problem associated with loosening fasteners in continuous vibration application.  This was cleverly resolved in 1944, when Louis C. Huck sketched the first vibration-resistant lock bolt, which went on to become the famous Huck bolt. Read the History of Huck. 

What are the benefits of Huck Bolts?

Huck bolt offer numerous benefits over other fastening methods including quick installs, easy inspections, good appearances and high-durability. 

  • Improved productivity with faster installations: Huck bolts are placed in seconds.
  • High shear & tensile strength, making them ideal in critical applications.
  • Vibration & weather resistance solution, once swaged they will never loosen.
  • Easy to use Huck guns, that come in a choice of air, cordless, or hydraulics.  
  • Quick inspections are sufficient to ensure correct installations.

What are the 3 main Huck bolt categories?

Unlike the 1940’s where there was only one Huck bolt, today there are numerous categories with many different options for specific applications. Huck Bolt fasteners are often used in trucks, truck trailers, steel bridges, railway tracks and trains, mining and agricultural equipment and many other structural applications where vibration is present. Here we present the 3 main Huck bolt categories.

Huck Bolt Magna-Grip

The standard diameter Huck Bolt. In applications where material thicknesses can vary, the Huck Bolt "Magna-Grip®" with its flexible material grip range is the ideal fastener. This Huck bolt is renowned for its superior vibration resistance and neat appearance. Magna-Grips®  have a starting pin diameter of 4.8 mm (3/16") through 9.5 mm (3/8"), click here if you want to convert imperial to metric. Huck Bolt MG are often used in the fabrication of trucks, truck trailers, ute trays, ute canopy bodies, emergency vehicles and numerous other fabricated products, where a vibration resistance fastener is critical to the application. 

Huckbolt C50L

The C50L is a large diameter bolt that has defined Huck for over 50 years. It is a heavy-duty lock bolt that has faithfully served Australia's heavy engineering sector with its great clamping power in numerous critical applications including Sydney’s Harbour Bridge. The C50L fastener has a starting diameter size of 12.7mm (1/2") through to 28.57mm (1-1/8"), making it the perfect large diameter lock bolt for mining equipment, truck chassis, steel bridges, and railway track applications. 

Hucktainer Lock Bolt

The Hucktainer was designed for fiberglass reinforced plywood (FRP). It is a specialty lock bolt fastener that avoids crushing FRP panels and provides a low-profile fastener on both sides of the application. Hucktainers feature a heavy zinc plating that resists corrosion and rust stains, making them ideal for attaching highly used components such as hinges, latches, and locks on truck doors. 

3 Key Things to Know About Huck Bolts

  1. Superior and permanent alternative to welding and nuts & bolts. 
  2. Extremely high vibration resistance with no follow-up maintenance required.
  3. Fast & easy installations. Minimal training & faster installation than nuts & bolts and welding.

5 Reasons to Use Huck Bolts Over Welding

For many years, welding was the only way to ensure the integrity of joints in demanding load-bearing or high-vibration applications. However, the lack of regulation covering steel manufacturing and fabrication has become a quality issue as the government has eradicated the regulations that mandated compliance to Australian Standards. Huck bolts overcome numerous quality issues associated with welding and the reasons to use Huck bolts over welding are many.

  1. Huck bolts are safe compared to welding. Welding comes with many health issues, along with spark risks, as numerous fires have been started by random sparks.
  2. Fast and easy installations that save you money. Installing Huck bolts  requires minimal training, unlike welding. Surface preparation is not critical with Huck bolts and human error is reduced.   
  3. Huck bolts are immune from the issues of heat-affected zones (HAZ). This can cause material strength issues whereas Huck bolts avoid thermal expansion issues.
  4. Regular Inspections. Huck bolts allow for quick inspection, whereas welds are difficult to inspect and the inspections often require expensive equipment.
  5. Easier to modify. Unlike welding, you can easily remove and rework a Huck bolt. Welding on the other hand is extremely difficult and requires a trained operator to rework once the weld is set.
