Extended washer PW10 E90 /100pcs/ 651044

Enlarged washer – solid support for your installations

The PW10 enlarged washer is an element used to connect components in installation systems. Made of steel with a galvanized surface, it provides a reliable and durable connection. Its design, with a round hole and outer diameter of 30 mm and inner diameter of 10 mm, is adapted to metric screws size 10.

Functionality and safety in one

The PW10 washer meets the requirements of the E90 functional maintenance system according to DIN 4102-12. This means that it ensures at least 90 minutes of functional maintenance of devices in the building in the event of a fire. This is crucial for ensuring the continued operation of fire alarm systems, fire alarm systems and emergency lighting, especially in buildings equipped with water sprinklers.

Constructional and material features

The steel used guarantees strength and resistance to mechanical damage. Galvanic/electrolytic galvanizing protects against corrosion, which extends the life of the washer even in harsh environmental conditions. The lack of edge chamfering ensures uniform pressure distribution and minimizes the risk of damage to the connected elements. This makes the washer universal and can be used by both professional installers and end customers during self-assembly. It is worth remembering that on request a version made of hot-dip galvanized steel (PN-EN ISO 1461:2023-02) or stainless steel is available, which allows you to adapt the product to specific project needs.
