The Benefits of Huck Bolts

Huck Bolts, they last forever

Huck Bolts are designed to provide permanent, vibration-resistant solutions for numerous applications. Their high strength properties means they are well suited to applications where a strong joint is integral to the structure. They lower installation cost, whilst being a clean and safe alternative to welding and a better option than a standard bolt and nut combo.    

The Huck bolt was developed to solve the problem associated with loosening fasteners in applications with continuous vibration.  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. 

What is a Huck bolt?

Huck bolts are fundamentally a two-piece threaded pin and a collar combo where the collar fits over the pin and is swaged together via a designated tool. The tool presses the collar into the pin making the two-piece combo a one-piece entity.

Benefits of Huck Bolts

Huck bolts offer numerous benefits over other fastening methods including quick installations, easy inspections, high-durability, and cost savings.

  • Fast installations: Huck bolts are placed in seconds.
  • High shear & tensile strength, making them ideal in critical applications.
  • Vibration resistance solution: Huck bolts will never loosen.
  • Easy to use air, cordless, and hydraulic tools that are rugged and robust.
  • Quick inspections are sufficient to ensure correct installations.

3 Main Huck Bolt Types

Unlike the 1940’s where there was only one Huck bolt, today there are numerous types with many different options for specific applications. Huck Bolts 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 types.

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.  It is 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 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 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. The Hucktainer lock bolt provides increased production rates, better joints and lower installation costs. How clever is Huck!

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 safer than welding. Welding comes with many health issues, including lung cancer, retina damage and asthma. With welding there are also spark risks, with numerous fires having been started by random sparks.
  2. Fast and easy installations that save you money. Huck bolt installation requires minimal training and improves productively compared to welding. Surface preparation is not critical with Huck bolts and human error is significantly reduced.   
  3. Huck bolts are immune to 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.
