Huck Bolts and Rivets

Huck bolts, Blind Rivets and Huck Guns 

Huck Bolt Authorised Distributor 

Huck bolts & high strength Huck structural rivets are designed to provide permanent, vibration-resistant fasteners for numerous industrial applications.  Huck bolt fasteners offer relatively high tensile and shear strength that are suited to applications where the joint is integral to the structure. Offering a clean and safe alternative to welding and a more efficient fastening method than standard nuts and bolts, Huck bolts and Huck rivets include many renowned many fasteners with their own individual feature to suit a your application and offer benefits which other fastening methods cannot, including quick and easy installation, elimination of re-checking / replacement, and ultimately cost reductions. When its Huck, you know it works!

Each Huck bolt and Huck Blind Rivet has its own characteristics ensuring that we have the right fastener for every application.

Huck is constantly developing new lock bolt 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 Huck Bolts 2 piece fasteners 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 Huck 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.

1. Bulbing

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.

2. Expanding

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.
