The Key Benefits of Huck Blind Fasteners

  1. Quick & consistent installation

  2. Permanent, vibration resistant joints

  3. Lower lifetime joint cost

What is a Structural Blind Fastener?

A structural blind rivet is a specialised fastener designed to solve manufacturing problems, offering signficant benefits over welding and bolting.

If you're experiencing issues with vibration, long-term fastener performance and maintenance, or simply want to reduce your assembly times then Huck blind rivets can be the solution. Key benefits include:

1) Improved Assembly - strucural blind rivet installations are quick, simple and efficient, reducing assembly time and increasing production throughput
2) Improved Performance - structural blind rivet joints are vibration-resistant, improving your finished product, minimising maintenance and cutting lifetime cost

In addition to the large portfolio of standard blind products the Huck team can engineer a custom structural rivet to specifically fit your application requirements. Contact us to speak to an engineer. 

How do Blind Fasteners Work?

The installation process plays a key in the function of Huck strucural blind rivets. Instead of torque like bolting, blind rivets use specialised tooling systems to achieve a mechanically locked joint. 

This is achieved by pulling the pin from the access side of the joint, deforming the sleeve on the blind side and forcing the joined materials together. This creates an irreversable lock formed by the head on the access side and the expanded/bulbed sleeve on the blind side of the joint. A part of the pin is retained in the sleeve for extra strength. The process is highly repeatable but also delivers extremely consistent results. 

As prolific innovators of the structural blind fastening systems, the Huck team have an unrivalled knowledge of how blind rivets work, and how to design the best peforming fastener for any applications.

Installation Sequence

The installation sequence for Huck structural blind rivets is very simple. The user inserts the fastener into the prepared hole from the front side of the application (the rear-side or 'blind'-side is often inaccessible).

The tool is presented to the application and the nose assembly placed over the pin. Once the trigger is pulled the tool will automatically pull the pin, compress the sleeve, break the pin-tail from the pin and release from the application.

  1. Pin placed into prepared hole, tools is placed over the fastener pin-tail

  2. Tool activated, deforming of blind side begins

  3. Joint tightened, internal locking mechanism formed

  4. Pintail breaks, installation complete

Tooling

A specialised tooling set is required to install Huck structural blind rivets. Installation tools are available in battery, pneumatic (air) and hydraulic (oil) powered versions.

A separate nose assembly is attached to the tool to fit each specific family/diameter of fastener(s). For pneumatic tools an air supply is required, for hydraulic tools a hydraulic powering unit is required.
