Huck Blind Rivets
Huck Rivet Guide. The original vibration resistant structural rivet.
Aerobolt has the complete Huck's rivet range including the original multi-grip rivet "Magna-Lok", the Huck "Magna-Bulb" with its superior strength and the hybrid "Huckloc" which combines key features of both the Magna-Lok and Magna Bulb. In challenging applications you can rely on the on the world's strongest, most reliable, most consistent blind fastening solution available.
Huck blind rivets are ideal when seeking a permanent joining solution in applications where vibration is an issue, due to their superior strength. In fact, Magna-Lok has been lab tested against their nearest competitor product and outlasted them by almost 20 to 1. In laboratory settings, Huck structural rivets lasted 2 million cycles whilst the other lasted 100,000. Huck rivets are the smart option that have engineered with an internal locking system that mechanically interlocks the pin into the sleeve during installation, whilst embracing the material - how clever is that?
Here we list below an overview of the main Huck rivets however there is a comprehensive selection at structural rivets.
Huck Rivet "Magna-Lok"
Huck Rivet Magna-Lok is a high performing locking rivet with extended material grip range, along with Huck's unique 360 degrees internal locking mechanism ensuring great resistance to vibration and moisture. A high performing structural blind pop rivet that will reduce inventory, cost, and labour.
Magna-Bulb Huck RivetsHuck Blind Rivet (MB) are renowned for their excellent shear & tensile strength among most other structural rivets on the market. When installed they produce a wide blind side footprint designed to spread the load, this is ideal in thin sheet fabrication.
The "Hucklok" Structural Rivet
Huck Rivet Huckloc is a double locking wide-grip range locking rivet, combining the extended grip range of the original Huck Magna-Lok and the strength of the Huck MB rivet has resulted in a rivet like no other, a rivet that locks material from both sides with excellent shear and pull-up force.
"Huck-Tite" Aluminium Structural Rivet
Huck Rivet Huck-Tite is an aluminium super strong rivet that pulls up into a propeller shape configuration making them ideal for lightweight materials plus a sealant for weatherproofing the joint.
Huck Rivet "BOM"
Huck BOM Rivets are often used as a replacement for welding, Huck BOM rivets are so strong that one BOM fastener does the work of up to four conventional fasteners. Ideal for military vehicles, high security fencing, and so much more.
How do Huck Structural rivets work?
Huck rivets work differently to standard rivets, as there is an internal mechanism that locks a portion of the pin (mandrel) inside the rivet's body. This creates an additional layer of material that assists in increasing the rivets strength.
When a Huck structural rivet is installed, the body changes in one of the following ways as it interlocks itself into place.
1. Broadening of the Body
Body widens when the cap of the pin is pulled up, resulting in the body expanding against the material.
2. Body Compresses & Bulges
Rivet's body is compressed by the pin cap, causing it to bulge and form a bulb against the material.
3. Body Splits & Folds
The slotted body folds and splits into a propeller shape blind–side anchor, ideal for lightweight material.
How do you install a Huck structural rivet?
Installation of a structural rivet is similar to the standard rivet, the difference being the tool, as a structural rivet requires a Huck gun or a structural rivet gun, because a standard rivet gun is not equipped to install structural rivets.
To install a structural rivet, pre drilling of holes is required. Load rivet’s pin tail section into rivet gun. Insert rivets body into hole and activate gun. Upon activation the head of the rivet is pushed against the nose of the tool, whilst the tool pulls up the central pin. As a result, the body compresses, and expands on the blind side until it maxes out to approximately one and a half times the size of the original diameter. Resulting in a larger surface in which the two materials are effectively fastened together.
Which is the best structural rivet gun?
Selecting the correct rivet gun depends on the nature of the project + your specific requirements, below we cover the main rivet gun categories, along with their pros. & cons. At Aerobolt, we stock a wide range of popular brand rivet guns plus a few alternative options that we have benchmarked for quality and value. Our site has extensive information covering most tools for you to review. To discuss further, simply contact us.
Structural rivets guns are broken down to two main types
- Huck guns that install both structural rivets and Huck bolts (pin & collar).
- Rivet guns that install structural and or standard rivets. Note that not all rivet guns are capable of installing structural rivets. Here at Aerobolt, we have both options.
These tools are suitable for the installation of both Huck bolts and Huck structural rivets with the simple changeover of a nose assembly (priced separately).
Air Huck Guns: For frequent installation, an air-powered Huck gun is the easiest choice for the job. Air powered Huck guns offer fast installations with consistent results. Some of the pros include: Easy to use, economical (cost saving compared to cordless), and no physical exertion required. They will also install to a set pressure / stroke. Cons: Requires an air source such as a compressor, possibly limiting mobility and making remote use impractical.
Cordless Battery Huck guns: Cordless Huck guns run on battery power and provide incredible versatility, allowing you to install Huck fasteners from practically anywhere. Like air tools, battery-powered tools are basically point-and-shoot. Pros: Mobility, speed. Cons: Batteries have limited charge before needing to be plugged in again, cost.
These guns are suitable for the installation of both structural and standard rivets, i.e. they do not install pin and collar Huck Bolts. They do not require a separate nose assembly and are generally an economical alternative to a Huck guns.

For the occasional installation of structural rivets, manual tools are your most cost-effective option, subject to purchasing a quality tool. They work by adding the rivet to the end of the tool, squeezing the handles, and retracting the tool from the now applied rivet. Some of the pros include: Inexpensive, easy to use, great for the handy person. Cons: They require physical force.
What are the advantages of Huck structural rivets?
Huck structural rivets are renowned for their strength and are the superior option compared to most other fasteners, key advantages include:
- One side assembly for fast installations as access to the rear is not required.
- Super strong, forming a mechanically activated permanent joining solution.
- Vibration and weather resistant. Offering high shear & tensile strength.
- Easy to use air, cordless, air and manual tools that are rugged & robust.
- Design flexibility, wide range of types, material, etc. to suit most applications.
- Easy inspection and maintenance, no expensive equipment for quality control.
What's the difference between Monobolt® and Magna-Lok®?
These popular brands of structural rivets may have many physical similarities however their strength is the key difference. Magna-Lok® rivet is a much stronger rivet, in lab tests it has outlasted the Monobolt® 20 to 1. Another key difference is Magna-Lok does not require a special nose tip to be installed correctly, unlike the Monobolt® which requires a special nose tip. Huck’s locking mechanism has been engineered into the rivet to eliminate tooling and operator error (subject to using the correct installation gun). Read more about the differences.
How do I select the right Huck structural rivet?
When considering selection you will need to look at; materials, diameter (size), grip range, head style, and strength. Here we look into the important criteria to consider prior to making a final decision.
Ensure the rivet material is compatible with the material being joined to avoid galvanic corrosion. As a rule, avoid using aluminium and stainless steel together, we recommend keeping the metal material like for like for maximum life. Stainless with stainless, aluminium with aluminium, etc.
* Above table is a guide only
x Incompatible, must not be in contact
Compatible in rural & mild environments (some corrossion may occur in marine/industrial environments. Painting both metals will reduce reaction)
Diameters & Hole Sizes
The size of the rivet diameter & the drill hole size is critical for success. If the rivets diameter is too small for its hole, then the gap may cause installation failure. Referring to the hole diameters before drilling is an easy way to avoid issues later.
Material Grip Range
The material grip range refers to the material thickness or the depth the rivet can be effectively installed. For example, if two 1.5 mm plates/items need to be riveted, a blind rivet with a material grip range between 2- 5 mm is required. Best practice dictates that the middle grip range of a rivet should be used and not the minimum/maximum sizes. This assists in achieving correct shear and tensile strength whilst ensuring the longevity of the rivet. Please note that the grip range is not the length of the rivet as many people mistakenly believe the length is the amount of material the rivet will pull up.
The rivet head type assists in holding the material together and enhancing its appearances. Dome heads sit proudly above the material, whilst large flange or truss head is a shallower broader head profile & suited for thin or soft material items like thin steel sheeting. The countersunk option provides a flush neat finish subject to countersinking the hole, allowing the head to sit level with the surrounding material.
Frequently Asked Structural Rivet Questions.
How do I install rivets?
To install a rivet, pre drilling of hole is required. Load rivet’s pin mandrel into rivet gun. Insert rivets body into hole and activate gun. Upon activation the head of the rivet is pushed against the outer surface of the tool, whilst the tool pulls up the central pin (mandrel). As a result, the bottom portion of the rivet compresses, and expands on the blind side. This expansion maxes out when it reaches approximately one and a half times the size of the original diameter. Resulting in a larger surface in which the two materials are effectively fastened together.
How does a rivet work?
Below we illustrate how a rivet works. Essentially a rivet is a metal tube with a pin (mandrel) through it, upon installation the pin's head is shaped to expand the tube & lock up the material.
What is the difference between the pop rivet and blind rivet?
Many customers ask this question and the short answer is there is no difference. They are two labels for the same item, a blind rivet means you do not need access to the other side of the material, or you can't see the other side of the material. Also known as Pop® rivets because it is the brand name of the original rivet company.
Why are rivets used on airplanes?
Rivets are the preferred choice of fasteners in the construction of airplanes because they can withstand extreme stress without breaking, whilst barely succumbing to damage. They are used in aerospace manufacturing because it simplifies both production and the maintenance of the aircraft.
Can I get coloured structural rivets?
Yes, Aerobolt offers painted structural rivets. They cost a little extra compared to the mill (raw) finish and are available in a wide range of colours. Refer to the Colorbond ® colour chart for selection.
