Extended washer PW8 650944

Enlarged washers – solidity and connection safety

Enlarged washers PW8 are fastening elements widely used in construction, electrical and mechanical installations. Made of steel, with a galvanized surface, they provide durable and reliable connections. Their role is crucial where stability and corrosion resistance are required.

These washers are particularly important in systems maintaining the functionality of E90, in accordance with DIN 4102-12. This means that in the event of a fire, structural elements and installations secured with these washers will maintain their functionality for at least 90 minutes – crucial for evacuation and rescue operations. Therefore, they are indispensable in buildings equipped with fire alarm systems, fire alarm systems and sprinkler systems.

Features and application

The PW8 washer is characterized by an outer diameter of 24 mm and an inner diameter of 8 mm, making it compatible with metric screws size M8. Galvanic coating provides protection against corrosion, which is particularly important in environments exposed to moisture or atmospheric factors. The lack of edge chamfering ensures uniform load distribution on the joined elements. The round hole precisely fits the screw, minimizing the risk of loosening the connection.

These washers are used for:

• Assembly of steel structures
• Joining machine and equipment elements
• Electrical installations (especially in fire protection systems)
• General construction
• Mounting interior fittings

Product advantages
