Huck Bolts and Rivets
Huck bolts, Rivets and Huck Guns.
Australia's # 1 Official Huck Bolt Fastener Distributor.
Huck lock bolts & Huck's structural rivets are designed to provide permanent, vibration-resistant solutions, offering a high tensile and shear strength in critical applications where the joint is integral to the structure strength. A clean safe alternative to welding and a more efficient fastening method than standard nuts and bolts.
It's the proven reliable, vibration-resistant locking performance that has made Huck fasteners world famous.
Huck bolts and Huck rivets have their own individual features to suit a your application, offering cost saving benefits that other fasteners or welding options can't match with quick & easy installation as skilled labour is not required and so much more. When its Huck, you know it works!
Each Huck bolt and structural rivet has its own characteristics ensuring that we have the right fastener for every application.
Huck is constantly developing new lock bolts and rivets to meet the diverse and changing customer requirements. The most recent addition to the Huck range is the Bobtail which offers superior performance combined with reduced noise, increased installation speed and elimination of pintails as well as more efficient and lighter tooling.
Huck offers over a century of experience creating innovative fastener products and solutions serving the mining, railway, commercial transportation, automotive, industrial, and construction markets. Huck bolts and Huck rivets and assoviated installation tools are used to assemble everything from mining screens, feeders, ore wagons, trucks and truck trailers, buses, railcars, and automobiles to HVAC equipment, satellite dishes, electronic cabinetry, green energy and shopping carts.

How Huckbolts Works
How does Huck Bolt pin & collar combo work?
Clamp Force or Pre–Load: In the initial stages of the installation process, the 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 of LockBolts vary 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.
The tensile strength of LockBolts is dependent on the shear resistance of the collar material and the number of grooves it fills.
How does Huck structural rivets work?
The shear strength of structural blind fasteners is generated by the combined resistance against failure of the pin and sleeve. This takes place along the joint’s shear line between fastened plates.
The tensile strength of structural blind fasteners differs to that of LockBolts, as they form a blind side positive lock either by bulbing or expanding of the sleeve. The sleeve, assisted by the permanently secured pin, therefore resists failure along its centre line.
The sleeve of the fastener is compressed, causing it to fold outwards to form a bulb. This forms itself tightly against the joint material. Once the pin is permanently locked into place the pintail will break off, completing the installation.
Pulling on the pintail causes the head of the pin to draw into the sleeve. This expansion causes a foot print to form against the joint material.
Note: The pre-load of blind rivets is generally not published, as it varies widely depending on the application.
