As manufacturing heats up and the demand for energy continues to rise, producers and manufacturers of equipment face increasing pressure to build faster – in an environment where safety is non-negotiable and skilled labor hard to find. The solution may be finding alternatives to traditional joining methods.
Extend Product Lifespan and Reduce Maintenance
For joints requiring high strength or controlled mechanical values, Huckbolts® (also known as lockbolts) are viable alternatives to both welding and conventional threaded fasteners.
Unlike conventional torque-type fasteners, Huckbolts® install with direct tension. The technology works by re-forming a collar (similar to a nut) into the lock grooves of the pin. The consistent mechanical values generated create secure joints throughout the platform.
This installation process produces a consistent and predictable bolt stretch load every time. In oil and gas applications—where structural integrity is critical—the consistent tightness this stretch creates will ensure reliable joints and reduce the risk of fastener failure.
Another benefit of direct tension fastening is that re-forming the collar into the lock grooves eliminates gaps that allow conventional fasteners to loosen under transverse vibration. Not only are the connections durable and vibration resistant, Huckbolts® never need retightening.
Benefits of Huckbolts in Critical Joints
The greatest advantage of Huckbolts® is their resistance to vibration. Once installed, they form a strong, reliable connection that typically requires zero maintenance, reducing service and warranty costs.
Lockbolts provide consistent bolt stretch, high shear resistance, and exceptional tensile strength, making them ideal for heavy-duty structures. In oil and gas operations, they are ideal for structures such as offshore platforms, drilling rigs, pipeline support structures, storage tanks, and processing equipment. Their strength allows them to handle large loads while maintaining joint integrity over long periods.
Addressing the Skills Gap
Huck® fasteners were invented to address a skills gap in World War II, replacing buck rivets on B-24 Liberator bombers with a fastener that installed significantly fastener and didn’t require skilled labor. Every iteration of that original design has delivered on that promise.
Today, Huck® fasteners can be installed with a variety of ergonomic tools ranging from full hydraulic tools that deliver unmatched installation speed to the new battery lineup for optimum flexibility.
Every tool in the lineup is easy-to-learn, with intuitive controls that that allow operators to get trained and on the job quickly – with no special skills or certifications. And quality checks can be performed visually, without special equipment or destructive testing needed to ensure consistent, strong joints.
In addition, fastening with Huckbolts® improves employee health and safety. Huck® tooling operates with a single trigger press, eliminating repetitive strain injuries from torque-type tooling like tendonitis and white finger. Battery tools remove trip hazards from cords and hoses, and there is a wide variety of options and accessories to address tool weight issues.
The Future of Fastening
Great for tamper-resistant applications, traditional Huckbolts® prove difficult to remove for service or repair without specialized tools or destructive methods.
The newest innovation, Huck® Bobtail® R, was designed to solve this long-standing problem. It provides the same vibration -resistant, maintenance free strength expected from Huckbolts® but introduces an important improvement: it can be removed using standard torque tools.
Built to solve problems that couldn’t wait, Huck® fasteners have been used for generations in applications ranging from bridges to locomotives to ocean-going vessels. Newer variants of Huckbolts® and Huck® structural blind fasteners can be found in a variety of military platforms, Class 8 trucks, and modular buildings.
Trusted, tested, and proven, traditional and removable Huckbolts® are ideally suited for drilling rigs, pumps, compressors, and pipeline systems that experience constant vibration and dynamic loads. They are also ideal solutions for remote or offshore environments where maintenance access can be difficult and expensive. By maintaining secure joints under extreme conditions, lockbolts help reduce operational risks and improve overall safety.
The oil & gas industry demands speed, safety, and reliability – qualities that traditional joining methods struggle to deliver simultaneously. Huckbolts® and their latest evolution, Huck® Bobtail® R, offer a compelling alternative: they combine the strength and vibration resistance of conventional lockbolts with a maintenance free, direct tension installation that eliminates the need for retightening. By ensuring consistent bolt stretch, preventing loosening under vibration, and enabling quick, ergonomic assembly, these fasteners reduce labor costs, shorten production cycles, and extend the service life of critical structures.
Looking ahead, Huck® fasteners will continue to evolve and adapt to the assemblies that need them, balancing tamper resistance with serviceability. As industries such as oil and gas, offshore platforms, and heavy equipment manufacturing push the boundaries of performance, the next generation of Huckbolts® will provide the same unmatched strength while offering easier removal with standard torque tools. In short, rethinking fastening with Huckbolts® means building faster, safer, and more reliably – today and into the future.
