Thread technology SPREDLOC®

Precision threads in modern lightweight structures — efficient expansion anchoring with one-sided accessibility

Your benefits at a glance:

- Pre-installed, one-piece fastener
- Stable stud threads according to property class 8.8
- Thread creation in formed and drilled tap holes — no holding thread required
- “Blind” setting method (one-sided accessibility)
- Suited for a wide range of lightweight materials*

*Not suitable for polymer materials susceptible to stress cracking, such as PC or PMMA.

Precision meets efficiency: The SPREDLOC® expansion stud in combination with the RIVKLE® Automation E

With SPREDLOC® and the RIVKLE® Automation E, Boellhoff presents two perfectly matched solutions for modern lightweight design and production requirements.

SPREDLOC® extends the Boellhoff portfolio with a threaded stud developed specifically for use in high-quality lightweight structures. This expansion stud creates wear-free and load-bearing threads and is suitable for a wide range of lightweight materials – including various polymers, aluminium and magnesium. The new joining solution is therefore of particular interest for structural components across various industrial sectors, such as the automotive and commercial vehicle industries.

True to the 360° Joining Technology approach, Boellhoff also pursues a consistent system approach with SPREDLOC®: upon request, customers receive the appropriate setting tool directly alongside the fastener. The elements are installed using proven RIVKLE® setting tools – from manual setting tools through to fully automated systems.

For demanding high-volume applications, the RIVKLE® Automation E provides a powerful automation solution. With its new drive concept, it combines performance and efficiency.
It is robust, cost-effective and, with its new web-based HMI software, provides reliable process monitoring. The low energy consumption and straightforward maintenance contribute to a sustainable reduction in operating costs.
