One of the challenges in heavy machinery is optimizing machine output and reliable equipment. Working in an industry such as trucking, railroad, mining, construction and manufacturing can be high demand, so it is critical your equipment is safe and can perform at its best in harsh conditions and outdoor environments.
That’s why so many businesses trust Huck® fasteners for their feeders, trucks, truck trailers, buses, railcars, mining screens and other equipment. Backed by over a century of experience creating innovative fastener solutions, Huck® fasteners are precision engineered to provide permanent, vibration-resistant joining solutions for industrial applications.
A clean and safe alternative to welding and a more efficient fastening method compared to standard nuts and bolts, the shear strength of Huck® fasteners makes them reliable in situations where a joint is integral to the durability of your equipment’s structure.
What are the benefits of Huck® fasteners?
Huck® fasteners offer multiple benefits that other fastening methods cannot – they are the tough solution to most fastening problems.
Quick and easy installation using simple tools can reduce production time by up to 75%. It also means you don’t need to invest in specialists for installation.
The reliability of the fastener means that you don’t need to re-check or replace it, which reduces overall costs to your equipment.
Each Huck® bolt and structural rivet has its own characteristics, so there are products available for each unique application and need.
Huck® fasteners will not loosen, even under extreme vibration.
Welding can pose a potential risk to workers due to random sparks and the safety hazard of spent rods and remnants on the assembly floor. Huck® fasteners offer a safer, cleaner alternative.
Once the Huck® fasteners are installed, they can’t be removed without specialist tools.
Huck’s fasteners solve the problem of any fasteners or bolts loosening over time by creating a tight fit and local system that can withstand rugged conditions.
Minimal training is required for operators installing the fasteners, eliminating the dependency on an operator’s skillset. The need to torque or apply a specified rotation to a threaded fastener has been eliminated and, as such, lessens the degree of skill required to effect proper installation. Unskilled operators with minimal training can quickly achieve consistently high-quality structural connections from first installation.
Quality control measures are simple to implement, as operators can easily visually inspect the fastener for the correct locking collar swaging during installation.
You will experience less downtime caused by bolt loosening and equipment failure.
Equipment performance is directly affected by weight – saving weight in your equipment is essential. Huck® fasteners can help lighten the load by offering a higher strength solution, meaning you can use less fasteners or a smaller diameter Huck®. They also allow for the use of lighter weight aluminum instead of steel in the joining process.
How do Huck fasteners work?
High strength fastening systems are installed with either manual, pneumatic or hydraulic installation equipment, making it user-friendly for operators. Using the most advanced fastening technology to date with a unique lock-bolt design, the strength of the fasteners comes from the shear resistance of the collar material and the number of grooves it fills.
What industries do Huck® fasteners thrive in?
Huck® fasteners thrive in structural applications where the working environment is subject to shock, vibration and dynamic loading. They are relied upon by businesses in many industrial markets including truck, trailer, stock crates, bus, rail, bridge work, automotive, HVAC, green energy (such as wind farms), agriculture, grain silo’s, mining, oil and gas.
Blind Bolt Characteristics
Most blind bolts are designed with a steel pin, a collar, and a sleeve.
There are various characteristics to consider when choosing the right blind bolt. You need to choose the right grip range length and diameter for optimal strength and lasting performance. You usually can find the right blind bolt dimensions by consulting the manufacturer’s range chart. You also have to choose the right material. Most commercial blind bolts are made of steel, but there are alternate materials, such as stainless steel and titanium blind bolts, for specialty applications such as aerospace. Once you select the right blind bolt for the job, you will have an extremely strong and lasting joint.
In addition to being strong, Huck® blind bolts are resistant to vibration. Once installed, they will not work loose over time or weaken under constant shaking. That is why they have become the fastener of choice for airplanes, railway cars, automobiles, factory equipment, mining equipment, ships—any application in which the bond has to maintain a strong connection under ongoing vibration.
Another attractive feature is that blind bolts are tamper-proof. Because they are installed using special equipment and have no screw heads, they can’t be vandalized, making them ideal for use in public transit systems, public restrooms, public buildings, or anywhere vandalism is an issue. The core bolt itself is very hard, which makes it difficult to remove without special equipment from the manufacturer. If you have the right equipment, you can remove a Huck® blind bolt and leave the parent material and the pre-drilled hole undamaged.
A Brief History of Blind Bolts
Wooden planes could no longer meet the needs of aircraft design, so engineers started to design airplanes made of aluminum, a material that was stronger, yet light enough for aircraft design. Initially, these aluminum airplanes were made using solid rivets, which made assembly slow and required two workmen, one on each side of the material being assembled. To address the problem, Jacques Chobert, one of the engineers at Aviation Developments, created a new riveting technology, the Chobert® riveting system, which could be installed from one side by one worker. Installation was still slow because fasteners had to be loaded and installed one at a time, so Aviation Developments created a tool that could hold multiple fasteners, which considerably sped up production.
Since World War II, the blind bolt has evolved to become a mainstay of manufacturing. New materials were adapted, as were new head configurations and designs. New methods were developed to machine the blind bolts so they became virtually invisible when painted. With these improvements, blind bolts became common in making aircraft ailerons and flaps, doors, floors, elevators, and so on. Pneumatic tools also were developed to speed up assembly. Over time, blind bolts were being made to join thin-gauge steel, plastics, fiberglass, and other materials. The automotive and electronics industries standardized Huck® blind fasteners for assembly uses. As new applications in aerospace and transportation emerged, new blind bolts were developed, capable of handling more extreme loads and temperatures. Uniquely designed structural rivets such as the Huck® BOM, Huck® Magnalok, and Huck® Magnabulb were developed for thin sheet materials. Eventually, blind bolts came to be used in place of rivets or bolts because of their ease of installation and superior performance.
Common Applications for Huck® BOM Blind Fasteners
Huck® BOM
The Highest Strength Blind Oversized Fastener Available
Blind bolts are used in almost every industry and application.
Often used as a replacement for welding, Huck® BOM is so strong, one BOM (Blind, Oversized
Mechanically locked) fastener can do the work of up to four conventional fasteners. Its unique push-
and-pull installation design makes it ideal for military vehicles, auto suspensions, rail car assembly,
and much more. BOM’s high fatigue thread form extends the life of any structure. Offering accurate,
easy, quick installation, BOM requires no special training or skills for operators.
The BOM® (Blind, Oversize Mechanically locked) fasteners from Alcoa Fastening Systems are so
strong, one can do the work of up to four ordinary fasteners.
You won’t find a more vibration resistant blind fastener, or one that works harder in so many
different applications. With its unique push-and-pull installation design, the BOM fastening system is
tough enough for military vehicles and equipment, auto suspensions, amusement park rides, rail car
assembly, and automatic storage and retrieval racks of shaft steel construction. Even the most
demanding high-tensile application is no match for the strength of the BOM fastening system.
Quick and Economical to Install and Inspect
Because installing BOM fasteners is so easy, a worker can learn the installation procedure in just 10
minutes, eliminating the need to hire certified welders or specially trained employees. And because
they install from just one side, they can be used in all blind side applications.
Installations are more accurate than other fasteners of the same kind, because the element of
human error is not an issue. In other words, correct installation doesn’t depend on operator skill or
specialized tools. Plus, chances are you can start using BOM fasteners immediately with your current
tools, saving you more money in the long run.

How Bobtail Works
Clamp Force or Pre–Load:
In the initial stages of the installation process, the tool engages and pulls on the tail of the fastener. The joint is pulled together before the anvil portion of the nose assembly is forced down the collar. This progressively locks (swages) it into the grooves of the harder pin. The pin and swaged collar combine to form the installed fastener. The squeezing action reduces the diameter of the collar, increasing its length. This in turn stretches the pin, generating a clamping force over the joint. The shear strength of BobTail fasteners varies according to the material strength and minimum diameter of the fastener. By increasing the diameter or the grade of material, the shear strength of the fastener can be increased. The tensile strength of BobTail Huck bolt fasteners is dependent on the shear resistance of the collar material and the number of grooves it fills.

A Lock Bolt is a two-piece fastener that consists of a hardened metal pin and a metal collar that swages into the grooves of the pin, forming a specific, measured clamp force to hold assembled parts.
The Huck® installation toolgrips the pintail of a Lock Bolt and then pulls to close the gaps in the materials being joined. Inside the nose assembly, a hardened steel conical-shaped anvil is then forced down the collar to progressively squeeze, or swage, the collar material into the grooves.
This direct metal-to-metal contact of the collar swaged into the grooves of the pin eliminates the loosening effects of transverse vibration.

How Do Huck® Bolts Work?
Clamp Force or Pre-Load
In the initial stages of the installation process, the Huck® lock bolt tool engages and pulls on the pintail. The joint is pulled together before the conical-shaped cavity of the nose assembly is forced down the collar. This progressively locks (swages) it into the grooves of the harder pin. The pin and swaged collar combine to form the installed fastener. The squeezing action reduces the diameter of the collar, increasing its length. This in turn stretches the pin, generating a clamp force over the joint.
Shear strength
Varies according to the material strength and minimal diameter of the fastener. By increasing the diameter or the grade of material, the shear strength of the fastener can be increased.
Tensile strength
The tensile strength of Lock Bolts is dependent on the shear resistance of the collar material and the number of grooves it fills.
Installing Huck® Bolts Using Huck Bolt Installation Tools.
Before installation, you need to make sure that you have the right size of Huck® bolts for the process. You would want to go for one that has the right size and strength for your needs.
Put the Huck® bolt in the hole prepared for it. Try to make sure that the bolt is the right fit for the application, or there are chances of lateral movement. This movement can weaken the joint over time.
When you place the Huck® bolt in the cavity, the collar will be over the pinhead. When you use a Huck® lockbolt installation tool for the process, the reliable collar will form a durable connection that lasts for years.
We have many different kinds of hydraulic machines that can help with your installation process. We have hydraulic and pneudraulic powered Huck® bolting machinesthat effectively help you install Huck® bolts in seconds. A few of our best products are the Swage forward Range and Huck® Range Force Battery Installation Tool.
From the wide range of tools available, try to choose the perfect match for your needs. Put the machine’s nosepiece into the collar, over the pintail. Activate the Huck® bolt tooling.
The activation process will put pressure on the collar and brings the pieces of the bolt together. It ensures a sturdy design that cannot become loose over time.
Once the process is complete, the tool breaks from the pintail, and you can remove the machine.
