Recently, Bossard Berzon Innovation has launched the ecosyn®-SEF multi-functional fastener. This product integrates self-locking nuts, conical spring washers and large contact surface washers into one piece. With just one part, it can meet multiple requirements, helping you easily overcome connection challenges in high-pressure conductive and vibration environments!
Solve all three major problems - anti-loosening, electrical connection and mechanical assembly - with just one component!
The ecosyn®-SEF combines self-locking nuts with conical spring washers and large contact surface washers, perfectly integrating the anti-loosening feature of the self-locking nuts, the elastic preload of the conical spring washers, and the pressure equalization advantage of the large contact surface washers:
01 Outstanding anti-vibration and anti-loosening performance Special thread design:
Effectively prevents loosening caused by vibration or external loads, ensuring the long-term stability of contact screws.Conical spring washers: Continuously provide elastic preload, compensating for relaxation caused by temperature changes or material settlement.
02 Reliable electrical connection guarantee Large contact surface washers:
Reduce surface pressure, avoid indentation of soft materials (such as aluminum, copper), and perfectly adapt to power transmission through long slots.Anti-surface damage: The washers reduce wear on the contact surface during repeated assembly, ensuring efficient and stable current transmission.
03 Wide applicability High-voltage conductive scenarios:
Electric vehicle batteries, transformers, power electronic equipment.
Mechanical connection scenarios: Slot screws, thermal expansion materials (such as composite materials), vibration environment fastening.
The ecosyn®-SEF breaks through traditional fastening solutions through functional integration design, bringing significant value to users:
Procurement and logistics simplification: Reduces the number of parts, lowers management costs
Assembly efficiency improvement: Shortens preparation and installation time, accelerates production rhythm
Error-proof design: Integrated structure avoids missing washers or springs
Automation-friendly: Higher process reliability, suitable for modern production lines
Connection is safer: Anti-vibration, anti-loosening, ensuring long-term stability
Reusability: Economical and environmentally friendly, reducing maintenance costs
ecosyn® - SEF nuts are particularly suitable for electrical connections, slot-type screw connections, and connections in vibrating environments.
